Cern Definition and 153 Threads

hello, I open this thread to ask some questions about SPS, it seems it is mounted 33 TeV, but how he has been able to reach him such energy? Is not it supposed to go up "only" 450 Gev Env? Good week

Hi! Does anyone know the most fundamental experiments that CERN did involving the discover of anything related to quarks? What is the most recent and important discover of CERN about quarks (heavy quarks)? Thank you.

Hey! So I found this ( http://home.web.cern.ch/about/updates/2014/11/beamline-schools-competition-2015-launches-today ) and my high school's physics teachers liked the concept! So I've created a team to participate in this years contest. We were thinking to do something relevant with antimatter...

I am thinking of places to do summer work placements in the high-energy physics field between each year of my degree. I have thought of CERN (of course) and Fermilab as the two definites. However I am struggling to think of a third. Also, I would prefer Europe/US so this rules out T2K. Any...

Due to the blogs being removed, I thought it might be worthwhile posting a few in the forums-The Large Hadron Collider has produced collisions at 7 TeV. For collisions at 7 TeV, protons need to be ‘ramped’ to 3.5 TeV, the proton has a mass of 1.6726e−27 kg which, according to mass–energy...

I have recently visited CERN, and in the Globe they showed an equation from string theory. My knowledge about it goes only as far as 'The elegant universe', so no mathematics, but i would say that the sketch beneath is about the string coupling constant. Could anyone please explain the...

So I've done some research, but to no avail. Can anyone link me to some reasonably detailed information regarding the Higgs experiment at CERN? I'm kind of new when it comes to this sort of thing. So a walkthrough of the experiment would be great (What they were looking for and why they were...

Hi guys, I have the idea of putting together a model collider that fires two smashable objects (eggs or whatever) at each other and show a high speed camera footage of the objects hitting each other - this is all as an analogy of what the hadron collider does at CERN. Any ideas what I...

Wikipedia says CERN has isolated about 38 atoms of antihydrogen and maintained them for over 15 minutes? ... Do you think that is possible? http://en.wikipedia.org/wiki/CERN

I want to ask someone here with a good practical background about the intrinsic quantum mechanical chirality (not helicty)...of say, a beta particle...Namely, What is the experimental proof of the existence of two distinct chiralities (not helicities) of the electron? IOWs, how can it be it...

I am interested in getting a PhD in Physics, but I do not want to teach. However, I do want to conduct research, is there anyway, I can have a job as a theoretical physicist working to participate in researches, maybe work in CERN, for the large haldron collider or something, without teaching in...

Hi everyone, I have studied QFT, the SM and the Higgs mechanism when I was in university and after reading an article from CMS (CERN) about the spin-parity measurement of the HZZ channel, which shows that J^{P}=0^+ is favoured versus J^{P}=0^-, I went back to the theory of the Higgs boson...

https://www.sciencenews.org/blog/context/it%E2%80%99s-too-soon-declare-supersymmetry-tragedy I have just been reading this and it seems to me another layer of complexion is needed to keep the theory alive. http://arxiv.org/ftp/arxiv/papers/1308/1308.4768.pdf Abstract The first three...

I'm double majoring in Chemistry / Materials Science & Engineering undergrad and I'm wandering yes it has engineering in the title but it also has Science as well. Is this engineering say more theory based than others? I read descriptions saying it designs metal alloys and everything like...

Hi, I'm a graduate in Mechanical Engineering (BEng 1st). The idea of further study has interested me for many years but I have never acted on it. Currently after working for a year and a half in the oil and gas industry I have the further education bug again, but I would love to follow it this...

I am currently confused... I read that we don't know yet where does the proton spin come from. But I wonder... 1) Doesn't the proton have effectively 3 quarks of spin 1/2 (I said effectively to leave out the quark-gluon sea within the proton)? In that case, 3 spin 1/2 particles can't be added...

I'm an undergrad at IPFW and I just got on this project setting up an optical trap. Our (my professors) main goal is to find out at what intensity (he keeps saying temperature) of light the objects behave as free particles. I see where this could be of interest, but aren't there bigger things...

I have, across the board, been rejected from all ten REUs that I applied to. A lot of them (CERN, Perimeter, SULI) make sense because of how prestigious they are, but I also failed to get into lesser know programs such as DAAD-RISE, Baylor, Columbia, Cornell, Indiana, Will&Mary, and Duke. I'd...

Hello, I am working in an experiment proposal for a contest at CERN, and I need reliable data about the Polar Aurora. The experiment consist in using a T9 beam to produce radiation similar to the Sun's radiation and irradiate with it a capsule with gas in conditions as close as possible to...

hi, i was just wondering does anyone know whether, now that Switzerland is pulling out of Schengen it could have any repercussions on people working in CERN and/or the research center itself?

Hi What is a positron? Is it a electron that moves faster? Why has it positive charge (has it anything to do with its speed?) When scientists at Cern do these "measurements", what can they use as evidence that a "positron" isn't just a electron? How do they know what positron is? How...

Is there any possibility that CERN has discovered a particle that appears like a Higgs, but simply could be some other particle that has a different function?

I am a young physics student currently attaining my A Levels, therefore my knowledge of this higher quantum physics is very limited. However, I have been given the oppotunity to possibly visit Cern, and conduct an experiment using the Proton beam (proton synchroton) and I must plan said...

Hi all, There is a CMS (Cern) program in which can display similar to the attached figures, do any one know what is it and how can I download ? S.

I would appreciate views on the following understanding of length and distance in SR, restricted here to inertial movement. This is the beginning of a follow up to the thread: https://www.physicsforums.com/showthread.php?t=724025 1. The spatial length of an object is the spatial separation...

Hi, I have been reading about CERN for a while and found amazing - amongst many other things - the fact that hadrons in the LHC turn some of their energy to mass after having reached the maximum possible speed. However this statement was not clear enough. I was wondering whether the mass they...

Hey guys, I'm in the middle of writing a lab report and I'm having trouble with my abstract. I know as a 3rd year uni student I should know how to write one by now. I feel it's a bit long, what do you think? How could I improve? I'm not asking you to write it for me just some hints. The...

Hi, I am currently a junior majoring physics/math and I am looking to get into a reasonably good REU for this coming summer. However, my gpa is EXACTLY 3.5 (from NYU-poly), and I have no way of knowing if this is considered high or low on the spectrum. I have applied to CERN and SULI, which are...

Hello everybody. I am going to propose an experiment with a proton beam at CERN for a contest. http://home.web.cern.ch/students-educators/spotlight/2013/competition-beam-line-schools. Also...

Hi all, I'd like to know what is the integrated luminosity of CMS exp. Cern ? S.

What is Antimatter -- really? I've been trying to get a grasp of what they ideal of antimatter is exactly. I do understand that it's the 'opposite' of 'matter'. Electronics, Neutrons, Protons, all have an 'opposite', and I've seen where the folks over at CERN have been smashing atoms together...

Hello! Next year I'm going to be freshman at Czech Technical University, in degree of Experimental Nuclear and Particle physics, oriented on Accelerator Hardware and Detectors. If i look at my past, i find myself always interested in accelerators. I would like to get my Bc. degree here, in...

Where would you use our new radiation detector? We are a student team from the Vienna University of Economics and Business. Currently we are working on project with the research center CERN and try to find different application possibilities for an innovative technology by interviewing...

Hi, experts I got a very naive question. I read the following sentence in a paper: "New results on the production of charged pions in p+p interactions are presented. The data come from a sample of 4.8 million inelastic events obtained with the NA49 detector at the CERN SPS at 158 GeV/c beam...

The charts at CERN show calculations that a 126 GeV Higgs boson is expected to decay to a bottom/anti-bottom quark combination 56% of the time. Do they mean as an Upsilon Meson which decays in a certain pattern according to the wiki meson decay charts? Or, do they mean independent bottom and...

Peter Higgs is going to get a Nobel prize for physics, since Higgs boson's existence was confirmed in the experiments in CERN. But I do have some questions: I read the following, but I'm not qualified to say if this is true or not, so I'm asking you for help, and if the following statement is...

Homework Statement This is not really homework, I am trying to understand relativity and I suppose my question is too simple to post in other forums. I took the following data from the Cern site when they reached 7TeV: 2. Relevant data Ek = 7 Tev (1.6926*1027 Hz) B = 8.33 T RLch = 4243 00 cm...

(I am going to attempt a 2nd, little thread before I finish my earlier thread. I want to see if I can practice using PF Rules & Guidelines and FAQ before I wrap up my thread on Autism in Medical Sciences.) In my humble opinion, the current budget crisis in the news likely augurs deep cuts -...

Hi, I'm new around here and I have a little bit of a problem. I'm a year 10 student (I know it's a little early) and I love the sciences, especially Physics. I really want to do a science at university but my parents don't want me to be a scientist. They want me to be a lawyer or a doctor or...

Greetings friendly physics folks, I could use some advice and/or general suggestions regarding a data visualization project I'm looking to get started on. If this looks like too much reading, please skip to the TL;DR below. The basic project components are: (1) A GUI of some kind...

Hi guys, I am ready to apply for PhD and one of my targets is STONY Brook (actually the only one in the USA since it won't require me to take any tests). Background: a) Undergrad at Lancaster University, BSc Theo. Physics b) Master's degree in Theo. Physics UAM/IFT in Madrid under...

This is quite an entertaining 15 minute video that provides a high level discussion for a general public audience. [A physics teacher and childhood friend uses the video in her advanced placement HS physics classes in New York. Her students are one group of US kids that I know get a good...

http://arxiv.org/abs/1303.1812 It seems that the recently discovered particle is indeed Higgs, as has been suspected.

Summary slide at the end (thanks to Peter Woit for flagging this talk as interesting): ==quote Lykken== Summary • There is no SUSY • There is no naturalness problem • There is no input Higgs potential: EWSB is generated radiatively • All masses come from dimensional transmutation and whatever...

BBC News reported this http://www.bbc.co.uk/news/science-environment-20300100 Here's the actual paper https://cdsweb.cern.ch/record/1493302/files/PAPER-2012-043.pdf What does this actually mean for Susy etc?

Hi, I was at a presentation re there recent anouncement by CERN, and the distinction between matter / dark matter / dark eneregy (matter versus the 96% of the universe that we don't know about) was repeatedly made. Given the findings relate to a particle with mass / properties not previously...

I was reading many articles last week about the Higgs Boson discovery and I noticed a passage in one of the articles saying that the accelarator at CERN has been operating at half power since it was put on line. Is that a true statement? Anybody? Do they ever intend on running at full...

Hi PF. I was wondering, if the newly observed particle @ CERN, could be a massive tensor boson, like a massive graviton. I have not been able to find out, whether ATLAS or CMS have determined if the new particle is a scalar, vector or tensor boson, so I thought it would be intersting, if the...
