Boson Definition and 371 Threads

This question is regarding the boson statistics and it’s relation to the uncertainty principle. Consider we have a vacuum state and we apply a field operator on it to create a particle at position x, we end up with state like \begin{array}{l} \left| \psi \right\rangle = {\psi ^\dag...

I'm not very good at physics but please forgive me. What will hapen now when we found the higgs boson: I have a proposition i don't know if it is posible but if someone can help and explain to me i will be greatiful. Is it possible that now when thay found the higgs to do the same like the...

why without the higgs boson, would particle physics be nonsense. why does this particle have such an important impact on particle physics. is this why it was called the god particle? its existence is unquestionably but no one had ever seen it. I bet when they discovered it the pa's were like...

Hi there, Just a quick question which I'm sure I'm over complicating in my head.:confused: I've read that Helium 4 is a Boson because it has 0 spin and that Helium 3 is a Fermion because it has 1/2 spin. Is this right? I don't see how whole atoms can be associated with fundamental particle...

Homework Statement Fermions and bosons combine through the reaction F + F + ΔE = B (so the creation of a single boson requires 2 fermions and some positive energy). What is the ratio of fermions to bosons at T = 0? Homework Equations 2[nF]/[nB] = K(T), where [nF] is the...

I don't understand these sentences from Peskin: "At long wavelength (*why long wavelength?*), the Goldstone bosons become infinitesimal symmetry rotations of the vacuum, ##Q^a|0 \rangle##, where ##Q^a## is the global charge associated with ##J^{\mu a}##. Thus, the operators ##J^{\mu a}## have...

So if W bosons decay so quickly from what are new W boson made? Is it made of an electron and anti-electron neutrino (which is what they decay into) but then again this wouldn't make sense since it is an "elementary" particle. Please clear my confusion.

Could someone please tell me what the symbols in the Zee.csv file mean on the CERN webpage (https://cms-docdb.cern.ch/cgi-bin/PublicDocDB/ShowDocument?docid=11581)? I am doing a project for my statistics class and that information would be useful. I'll appreciate any and all help.

I admit I am pretty much completely baffled by the concept of an additional particle being required to "give" other particles mass, but I would like to ask a simple question. given the extremely large amount of energy required to generate a higgs boson, how can such a particle come into play...

How come Higgs Bosons have mass if Higgs field itself gives other thin How come Higgs Bosons have mass if Higgs field itself gives other thing their mass?

i was just reading a article that said that if the higgs boson is proven for fact, then the concept of the mass effect (spacetime pressure and curvature) would be obsolete. Is this true? i spent so much time teaching my self about SR and GR.

This was released today so I'm not sure if most have seen it yet. It appears that "a" Higgs Boson is confirmed. http://home.web.cern.ch/about/updates/2013/03/new-results-indicate-new-particle-higgs-boson

Hi guys, Let us consider this thought experiment of having say Avogadro number of bosons in a box. According to statistical mechanics, it is equally probable to find every distribution of bosons in the box. But, say we wait really long enough to find that at one point of time, we find all the...

Firstly, thank you all for creating this forum, thank you all for tolerating my questions. As an expert in another subject, I know it's not easy to take time out of one's schedule to answer the questions of non-experts, and I am grateful that you guys have. That said, this question is a...

What are the accepted numbers for the decay rate and lifetime of Z-> mu+mu- and Z-> e+e- decays? also what is the unit for the decay rate? thank you!

Is Higgs boson a form of energy ? Hello all . We know Higgs boson or Higgs particle is a theoretical elementary particle and in the Standard Model, the Higgs particle is a boson with no spin, electric charge, or color charge and it just has mass . So what's the problem when we say they are...

http://cosmiclog.nbcnews.com/_news/2013/02/18/17006552-will-our-universe-end-in-a-big-slurp-higgs-like-particle-suggests-it-might?lite There are several news sites saying the discovery of the higgs boson indicates that the universe is a 'false vacuum' but they're very light on the details...

Hello all . If there is not higgs boson that mean all elementary particle travel velocity of light through space ?

These are things about the higgs boson that am confused with: 1: how does particle physics explain the weakness of gravity, since higgs is just another force carrier like any other, why is it so weak? 2: how do virtual bosons, popping in and out of existence, exchange between two particles...

How can we propose the existence of a massless graviton when the recent discovery of the higgs boson means that there is a Higgs field that endows everything with mass? Doesn't the higgs field disprove the graviton? In that case, we would now have no idea where gravity fundamentally comes from...

Why does the Z boson only decay to fermion-antifermion pairs? I'd just like to understand the basic reason why something like Z --> anti-down, strange wouldn't work. This would conserve charge. It obviously wouldn't conserve strangeness, but the weak interaction doesn't, so I'm just wondering...

Hi everyone and happy New Year. The Standard Model shows very specific and measurable couplings of the Higgs boson with the W and Z fields. What QUANTITATIVE measurements have been done to verify that these couplings are as predicted? Thanks and looking forward to your replies. A lot of...

1. The Problem I am trying to find the feynman rule which corresponds to the addition of an interaction term to the QED lagrangian which couples the electromagnetic field to a neutral massive vector boson field. In this problem, $$k^\mu$$ corresponds to the photon 4-momentum and $$q^\mu$$...

Hey, I have the following equation for the renormalised mass of some scalar particle (i.e. Higgs boson) m_{r}^{2}=m_{0}^{2}+\frac{\lambda}{32\pi^{2}}( \Lambda ^{2}-m_{0}^{2}ln(1+\frac{\Lambda^{2}}{\mu^{2}})) Where I have the first order correction to the mass of the loop in a two point...

Hi, a simple question on W boson vertices (and I guess field theory in general). If I have a W boson vertex for incoming particles, i.e. W^+ ubar d and W^- u dbar how do I change this for outgoing W's. The first interaction contains a CKM matrix element Vud and the second a Vud^*, and...

How is it possible that the Higgs boson interacts with itself? Now that it is almost certainly discovered, how can a particle that gives mass to other particles, give mass to itself? Does it make a 'loop' with other Higgs bosons? How can the Higgs boson interact with other particles in such...

Hi guys, I've read up things on the Higgs field and boson, including the analogy provided by the CERN website. However, what I don't understand is what exactly happens as the Higgs field interact with particles. And for particles, do they mean elementary ones like quarks? Or do they mean more...

I am reading the paper "Covariant Action for a D=11 Five-Brane with the Chiral Field" and want to make an analog for the chiral field in 2 dimensions. But I don't know at the starting point, for if I take the local coordinates of the worldvolume to be ##x^m (m=0,1)##, the dual field strength...

What does this mean? " spin +1 ("triplet") and is thus a boson." Hey, Can anyone explain the best they can what the following means? Its in response to a question I asked about a certain substance. " spin +1 ("triplet") and is thus a boson."

I ran into the following article by Varma, Higgs Boson in Superconductors http://arxiv.org/abs/cond-mat/0109409 Varma compares the Gross-Pitaevskii equation with the Higgs Lagrangian and calculates the elementary excitations. He shows that although symmetry is broken in both cases, Higgs...

Could a Fermion be Entangled with a Boson ?

Hi; Forgive me if this topic has been covered elsewhere; I'm new here and didn't find an answer to my question by searching the Higgs. With the potential discovery of the Higgs as announced this past July by CMS and ATLAS the one thing that I'm not understanding is why isn't the Higgs...

It is said that is there already n bosons in a particular quantum state, the probability of another boson joining them is (n+1) times larger than it would have been otherwise. But if we apply this rule to calculate probability for one horizontally (H) polarized photon to join a bunch of n=99...

The top quark has mass around 173GeV. The Higgs boson (probably) has only 125GeV. Why the top quark has been discovered earlier despite it has larger mass? Why did we need more powerful accelerator to detect a lighter particle? Is it possible that there are some other light particles within our...

Why in the standard model doesn't charge need a boson like mass needs the Higgs boson?

Can anybody throw light on the following doubts? 1.what is the implication of the recent discovery of the higgs boson in the quantum physics? Does it support the quantum nature of matter and wave and the uncertainty principle? 2. It is said that Einstein did not accept the quantum theory...

Why does the standard model have a higgs boson quadratic and a cuartic term but it does not have a cubic term? is there any problem if it happens to have a cubic term? Thanks!

Hi all. I have recently read an article that summarizes our knowledge about Higgs boson and the consequences of its existence and of the value of its mass. The author says that our universe could be stable, unstable or metastable and that the discrimination between this three options is give by...

I was thinking, because of the relationship between energy and mass and the mathematics, would it (theoretically speaking, of course) be possible to accelerate the Higgs Boson to the speed of light, reducing its mass value to 0 and converting that mass into energy? I was also wondering if this...

I know that the Higgs boson gives particles their mass. I know that there are two kinds of mass: inertial mass and gravitational mass. I know that the Higgs boson gives the inertial mass, but is there a relationship between it and gravity? If so, what is that relationship? As far as I know...

Hi If the Higgs field is present everywhere then so should be the Higgs Boson right? Then why is a particle accelerator required. Cant it be just detected from around us? Salil

Is the Higgs boson only a particle of pure mass? It has no charge, no spin, no color, no flavor, etc. Does it have any other non-zero characteristic besides just mass?

Real or fake? Since we still know so little about particle physics and related applications the question remains out there. I am curious to know what others think?

I am wondering why all force carriers we know are boson. Is there any special reason that fermion cannot be force carrier? or All known force carriers happen to be boson?

what particles?

I know they have been very close to it and seen something similar to the boson but did they actually find it? it's like the media has been blowing it up and saying they found it, but there was not official claim, it was just yeah we spend a garbageload of energy and time trying to find it, we...

If there is not a conservation of mass, then what happens to higgs-bosons? Are they destroyed, or decay into something else (if that is even possible...)?

Hi everybody, let's assume the Higg's boson exists. If I understand String theory correctly (and I understand very little of it), then Higg's particle - just as any other particle - can be expressed as a particular vibration state of a string. If I understand Higg's theory correctly, then...

I don't know much physics so it's not that easy to understand what a Higgs Boson or a Higgs field is. According to Wikipedia, a Higgs field is theorized to be the mechanism for giving elementary particles mass. For a lay-person, this makes me think that a Higgs field is something to do with...

From introductory QM class, my understanding is that one can consider any number of "fundamental" particles as a composite system and pretend it is a particle. When 2 fermions are considered as a single composite system/particle, it becomes a boson. When 1 fermion and 1 boson are considered...
