Higgs Definition and 684 Threads

okay, i am totally confused (again). i ihave a general understanding that the higgs mechanism is the effect which gives particles mass. the higgs mechanism is determined by the higgs field and mediated by the higgs boson. is that correct so far? now the HLC indicates that it has somehwat...

If the vacuum contains all these Higgs bosons, at expectation of <246> GeV in vacuum, why isn't there a cosmological constant, given the vacuum an energy density of 246 GeV^4 , instead we see dark energy at a few meV^4. Could just say that the graviton doesn't couple to the Higgs at all, but...

The Higgs bosons has no mass before it travels through the Higgs field. So is this the point where energy becomes mass?

Firstly, an open statement to everyone in this forum. I am in search of some answers to questions I have so that I may have a better understanding of this research. For this reason I have posted this so that through all of you my lack of education or some may refer to ignorance I may be...

Would electromagnetic coupling between an electron with charge e and an electromagnetic field with scalar potential V_em add to its mass in the same way as its coupling to the scalar Higgs field? i.e. mass_electron = g V_Higgs + e V_em Somewhere I got the picture that a left-handed...

From http://arxiv.org/abs/1112.2415, "Planck scale Boundary Conditions and the Higgs Mass", I learn of http://arxiv.org/abs/0912.0208, "Asymptotic safety of gravity and the Higgs boson mass", which predicts a Higgs mass of 127 GeV as a consequence of the vanishing of the Higgs self-interaction...

I understand that the the Higgs field has a vacuum expectation value of 246 GeV. I think that means that the expectation of the Hamiltonian energy operator applied to the vacuum state is 246 GeV. What does this imply for the energy density of the Higgs field in the vacuum (i.e. in Joules /...

Four days later there will be a CERN live broadcast of the seminar discussing the latest result in Higgs search with about 5 inverse femtobarn of data from both CMS and ATLAS. However, it starts at 5am Eastern Time! Do you know whether the video can be watched again in the afternoon?

There seem to be a number of news stories coming out about the possibility of an imminent find of the Higgs Boson @ 125-126GeV: http://www.bbc.co.uk/news/science-environment-16074411 So what if the elusive Higgs Boson is finally found? Could this somehow enable us to conquer and manipulate...

I did a search before posting. Posted yesterday, The Register, Rumours of Higgs sightings precede latest results seminar Form this link correct me if I am wrong, 3.5 sigma would be equal to: and 5 sigma, 233 parts per million would be enough confidence that the Higgs had been cornered...

I was wondering, if there was a hint or a strong signal of a Higgs particle existing around the 125 GeV region whether the possible future International Linear Collider would be able to probe that energy and produce Higgs to study? Also, if this is true, is it also true that the linear collider...

Refer page-24 in http://arxiv.org/abs/1010.0443v3 Eq-6.19 is supposed to be the Lagrangian of Abelian-Higgs models. Eg-6.19 is clearly a conserved current of U(1) symmetry. But I can't show how eq-6.21 is a conserved vortex current. Note: The last term in the Lagrangian is not the usual F_{\mu...

Higgs Confusion (The Higgs "Era") I thought I understood the basic concepts behind the Higgs mechanism (spontaneous symmetry breaking and such). But I've read a couple of sources that talk about the "Higgs Era" - the period shortly after the BB when the U was still hot/dense enough for the...

If the Higgs gives mass, wouldn't the Higgs give gravity too? If it exists that is.

Do you believe in the news that by December if no Higgs were found. It is like there are really no Higgs because the search windows have been narrowed down already to no more gap by December 31? If there were no Higgs. What other tests or results can the LHC design to see that can explain...

Just curious. As Space expands in our universe, does the space between Higgs particles expand or are more particles created to full the void?

Thought some people here might enjoy a little video we made: For context: Everybody involved in this project, in front of and behind the camera, is actually a theoretical physicist. This should obviously be taken as tongue in cheek, and it is not directed against string theory in...

Our universe apparently has a positive cosmological constant so it will look more and more like de Sitter spacetime, expanding at at exponentially increasing rate. So eventually it seems that subatomic spacetime would be affected by this. Eventually even something a Planck distance away would...

I was wondering if Higgs theory offers an explanation for why the Koide formula gives such precise masses for the leptons? I would assume that any theory of mass would be able to predict the masses of particles, especially for ones where precise relations have been found between them like the...

Where can get the Higgs equation for his model?

Hi to all, I am an electrical engineer so my knowledge about "heavy" physics is somewhat limited. I like reading about ( only superficially ) this "heavy" physics so I am puzzled about something and I need your help. Is Higgs boson strongly related with Higgs mechanism? We all know that...

This is an extremely speculative post. I came to know through a friend of mine, that his professor told him that CERN is going to announce by spring 2012 the closure of all Higgs and Supersymmetry related programs. I do not have any citation for this claim. More knowledgeable people can tell me...

Do we already know enough about the Higgs to be certain that we cannot interact with it(i.e. exert any type of control over it, like we can with electrons) or is there room for discovery there? I was just pondering some implications of such an ability, and realized that I don't know if the...

Somehow stumbled across this website Can't tell if it's made by a real physicist as a joke/parody or by someone who was dropped a few too many times. It looks like a lot of effort went into those diagrams though...

The standard model predicts, and relies on, the higgs boson. We have not witnessed it yet, because the energies required to do so were beyond us in the past. Current models predict, however, that (if the Higgs Boson exists) CERN WILL see it. I know its still early, but CERN hasn't turned up...

I can't resist voicing this idea. You can see its genesis http://johncostella.wordpress.com/2011/09/28/could-the-opera-tachyon-be-the-unbroken-higgs/" also contributed. The "logic" is as follows: The unbroken Higgs is a tachyonic object already found in the standard model. OPERA's FTL...

I read an interesting article http://www.scientificamerican.com/article.cfm?id=how-does-the-higgs-boson which says that string theory seems to require our world to have a property called supersymmetry and also, I have heard that the supersymmetry requires the eexistence of at least 5 Higgs...

Has a very light (less than 1eV) Higgs mass been excluded by theory and/or experiment?

..what then? What the are possible alternative theories then? thanks

If the Higgs is not discovered with the present generation of machines then would that really be an important discovery in its own right and could the tax paying public be convinced that their money had been well spent?

What were so strong arguments, that they go to such measurement? Why it is wrong to say simply, that Higgs does not exist? Why it is necessary?

I've had people explain this to me and I've watched a few videos but I'm still confused. Particles interacting with the 'Higgs field' gives them mass, but how much they interact with the field is determined by the mass of the particle in the first place. That doesn't seem to make sense so...

Why must it be a particle? I mean, if sub-atomic particles act as a wave and a particle why can't the higgs? Maybe the only reason we can't detect it is because we're looking for the particle and not the wave? Can someone please elaborate on this.

The Big Bang is seen by Alan Guth as having been produced by a relatively short burst of negative pressure, as a result of a high energy state that is temporarily trapped on some sort of non-zero plateau in the vacuum. I have a quote here from a popular science book by Green to clarify things...

http://arxiv.org/abs/1104.4642 Abstract "The newly found \cite{CDFnew} dijet peak in the 120 GeV to 160 GeV mass region produced in co-production with W IS actually a Higgs Boson in spite of the expectation of a different decay pattern for most Higgses. Our point, however, is that the bound...

I vaguely know the Higgs boson and how it possibly explains how mass doesn't dissipate. However, I need a more in-depth explanation, preferably not Wikipedia's, about it. Thank you!

I've read a couple articles about the recent incident at fermilab last week about them overlooking something. The Dzero team found something they missed. Well in the end it is said that the odds of the "god particle" being real have significantly gone down due to the results of this last...

Is the field of the theorized Higgs particle totally distinct from those fields which give rise to fleeting virtual particles? Would the latter also have some kind of 'drag' effect on elementary particles like the Higgs is thought to do? IH

If the postulated Higgs field has a non-zero vacuum expectation, shouldn't the typical black hole be ingesting Higgs particles at an alarming rate?

I apologize if this is a nonsensical suggestion/question. I would also like to apologize if this has been placed in the wrong forum. While surfing the Internet I suddenly had a thought. Could the Higgs field (HF after this) be interchangeable or combined with Space-Time? (to be called "ST"...

Hello, I am searching for information about the higgs mass before and after the symetry breaking. Does it depend on the temperature? I know other particles are not expected to have a mass before symetry breaking, but I suppose the higgs itself does. I don't find much informations about and I...

I'm trying to get a basic picture in my head of particles having mass. I always seem to come across the ridiculously vague statement that "the Higgs mechanism gives particles mass", and a passing mention of "spontaneous symmetry breaking". There is a lot of stuff confusing me at the minute so...

Hi guy's, this is my first thread at Physics-forums. I am currently working on GUT's and try to learn the Higgs mechanism. Therefore my supervisor gave me a toy model. This model is a SU(4) gauge theory with a infinite series of 4+ \bar 4 as Matter fields (fermions) and a Higgs sector which...

This might be a bit of a naive question but I am only just starting to learn the very basics of this stuff. I'm hearing about being able to account for the mass of, well, massive particles, by saying that in our cool universe, there is this field pervading all of space that certain...

http://science.discovery.com/tv/through-the-wormhole/episodes/what-are-we-made-of/ Discovery channel is running a very excellent episode on particle physics & the LHC hosted by Morgan Freeman and they mentioned something which I want to inquire further. It is mentioned in the program that...

How does moving at near the speed of light affect the geometry of space-time? How does an object increase in mass in relation to its speed? Does this have to with more collisions with the theoretical Higgs boson?

Is the Higgs boson and the Graviton two descriptions of the same thing?

The graviton (spin 2) and the Higgs boson (spin 0) are both involved in gravity. The Higgs carrying mass, and the graviton carrying the gravitational interaction. On the internet I red that a lot of people wonder if there is a connection. In electroweak interaction the forces are carried by...
