Boson Definition and 371 Threads

The Higgs boson was proposed to provide a mechanism for mass and is posited, as a field, to extend throughout the Universe. But this was before we started thinking the neutrino, which is also (almost) omnipresent, must have a mass. Could the neutrino substitute for the Higgs in this role?

Why is the (mass)^2 term of the Higgs Boson negative in the Standard Model Lagrangian to start with? I understand that along with the H^4 term, it gives rise to dynamical symmetry breaking, which explains a bunch of stuff (and eventually gives us a physical mass term for the Higgs). But I find...

Hey, If we use the Friedman Equation form to find time(excpected) for a given particle's Rest Mass energy as our input value, does it mean that the most energetic particles were 'born' first and the lighter particles 'born' later on in time in a linear, sequential order? eg. T quark...

I have searched in a lot of books and online resources, and none of them shed any light on why phonons are bosons. Can someone here help me?

[SOLVED] Slave Boson method I am currently writing a term paper for my many-body QM course about the slave boson method in strongly correlated electronic systems. Can someone perhaps point me to a paper to start with and move on from? I can't seem to find the paper that introduces the concept...

I'd like to ask some questions about the following example of broken symmetry and non-invariant vaccum. The basic argument goes as follows: \Cal L= \partial^\mu \phi \partial_\mu \phi \: - \: \mu^2 \phi^* \phi \: - \: \lambda (\phi^*\phi)^2 \frac{\partial V} {\partial \phi}=0...

Hi. I hope I'm posting in the right place. I was just wondering, what is the difference between the graviton and the higgs boson. I'm not quite sure, I think I sort of understand it... but not really. Also, since I don't want to make a new thread for such a small question, is there...

In thinking about Bose-Einstein condensation, an apparent contradiction came to mind ... Take the usual "particle in a box" potential and start filling it with identical spin-1/2 particles, two at a time. Also impose the rule that each pair of particles added must have opposite spin, i.e...

I'm wondering about the higgs boson, or "god particle". If it is said that it turned energy into matter, that has to be false, because it is matter itself. :cool:

an atom consists of an electron (spin 1/2) and a positively charged spin 2 particle at the nucleus (in place of the proton). is this 'atom' a boson or a fermion?

The decay rate of the Zo boson depends on the number of kinds of neutrino.Does each kind of neutrino contribute to the decay rate equally? Are there more electron neutrinos than muon or tau neutrinos?

In recent experiment about higgs boson, scientists use niobium. Why did they choose it then? Could the reason be the easiness of picking [or something like that, i don't know the exact word for it (:] electron?

Did that make any sense at all? The problem goes, and I do my best to translate from Enlish from Swedish: The mass of the intermediate vector boson Z is 97,1 times the mass of a protone, whos energy "at rest" is 938 MeV. a) Calculate the threshold temperature of Z. b) Calculate how long...

What is the estimate of the gravitron size and can someone explain why it must be spin 2 also what is the higgs boson it is expected to be massive, electrically neutral, and spinless. why. Cheers Woody

My friend is wondering if its possible to use the energy of a higgs boson to use in a turbine generator. Is that possible?

Is it possible that boson fields "absorb" matter the same way electrons "absorb" photons, thus explaining why we cannot detect them?

neutron => proton + W- => proton + electron + electron anti-neutrino What're the quarks composing W-? To convert a neutron to a proton, there would need to be the expulsion of a down anti-up pair. That would mean a tad bit of mass loss, how does this work?

Hi, I don't really know much about string theory, but I was wondering whether the discovery of the Higgs boson would back up string theory, or contradict it? Thanks.

Cern's Accelerator and Brookhaven's Relativistic Heavy Ion Collider labs are now capable of generating and detecting the Higgs Boson resonance. The nuclear reaction is as follows: Pu244(39 Tev) + Au197 -> CMS(39 Tev) -> H115.6 GeV(1 Tev) + E Ecms = (160 GeV/nucleon)* 244 nucleons = 39 Tev...

Hope some of the resident experts in particle physics can respond to it, because I'm unable to find a response to the question: Is a Goldstone boson the same thing that a Nambu-Goldstone boson? I suspect that is true because both particles are referred as massless, but I prefer the...
