Ok, newb question. I understand that the Higgs mediates 'mass'. But the graviton (if it exists) mediates gravitation, right? So I assume this means mass is being treated separately, with the Higgs mediating inertial mass and the graviton mediating active gravitational mass, right? So what about...
So now CERN have announced a 4.9 sigma discovery of a new Boson most likely the Higgs does this make the existence of the inlaton more pluasible , less plausible or make no difference whatsoever?
News just came out from a press conference, that the "god particle", a.k.a, the Higgs Boson has been affirmatively discovered. Analyzing the results of trillions of high energy collisions that took place in particle accelerators, physicists concluded that the higgs boson particle (or a particle...
The Higgs is supposed to couple to fermions but not photons. Nevertheless, photons add mass to systems in SR. Also kinetic energy (KE) of fermion motion adds inertia and mass to systems in SR theory. So, how does the Higgs field "tell" that this type of mass from photons and KE IS mass, and give...

For some reason the Higgs Boson has become famous well beyond those interested in physics. There is a schedule press conference at 9am Geneva at the site of the Large Hadron Collider and it seems that the only discovery warranting...

This is a graph from an article from last November on the search for the Higgs with the Atlas detector.
It shows the cross section for a Higgs process relative to the standard model prediction.
And then the upper limit of this, at the 95% confidence level. And this for different Higgs...
I have just watched a video by Professor Brian Cox. In it he describes the proposed Higgs field. If it exists, it is thought that this field permeates all space among other attributes.
When I heard this, it struck a familiar chord. It sounded almost identicle to the description of the aether...
If the Higgs field is responsible for embuing particles with mass, and mass is responsible for gravity, is it possible that the Higgs field will provide the missing link between general relativity and quantum mechanics ie could the Higgs field be the basis of a quantum theory of gravity?

Hi there. I have a question. Different QFT books usually introduce de Simmetry Breaking mechanism something like this:
1) We have a local gauge theory.
2) The theory has a parameter which is usually positive but can be negative
3) If this parameter is, let's say, negative then the vacuum is...
Soon, I believe on 4 July 2012, CERN is due to make an important announcement regarding the discovery (or not) of the Higgs particle at the LHC. This announcement is likely to be an important milestone in physics. It comes after a long drought of significant fundamental physics discoveries...

Homework Statement
I have decay of Higgs to fermion and antifermion and I need to find out the invariant, averaged amplitude.
And I wrote down the Feynman diagram, and calculated everything and I came to this part:

Layman, I have a problem to understand the Higgs' motivation back then at 1964.
The Higgs as I understand was postulated to explain how spontaneous breaking of gauge symmetry takes place in nature, which in turn explains why other elementary particles have mass.
This all make perfect sense...
I've been bugged by a question for some time.Everyone talks about the Higgs boson, although no one discovered it yet.My question is how do we know it's a particle?I mean, to me it'd make more sense if it were a wave created at the same time with the Big Bang that gave everything mass or if it...
Hello,
This is my first post and I'm by no means a professional, but I am trying to sort out my understanding of the Higgs field theory. As I understand it, particles acquire mass through their interaction with the Higgs field, an electron being the "lightest" and a Top Quark being the...
This is several questions crammed together because they overlap in my mind. Thanks!
Is the Higgs Field something that occupies the complete void of space, or is it thought to be a property of space itself?
Was the Higgs Field caught up in the mass of the pre-big bang singularity, or would...
So how will CERN's LHC produce a Higgs boson
I saw a video where a professor said
"So you do it by ... using e=mc^{2} ... you collide some protons at huge energies, so that's giving you energy, and that energy gets converted into the mass of all possible new particles that there can be"...
In blog discussions of the possible gamma-ray signal at 130 GeV (which is being interpreted as resulting from annihilation of dark matter particles), it's often asked whether this could have anything to do with a 125 GeV Higgs. And now I'm wondering: is it possible that the mass-splitting...
from the little info i have found it i gather we are still looking. where can i find more info? google just brings up wiki and some crap from cnn. i don't know much about it, however i would like to. if it gives other particles mass how can we find it in a particle collider? wouldn't it already...
The title says it all.
I've seen an example worked out, and there mass was given to a gauge boson specifically. Also, I wouldn't know why the Higgs boson would want to give mass to the fermions, since they already have mass in the Yang-Mills theories; it's only the gauge bosons that initially...
F=GM1M2/r^2
The force of gravity without mass is 0. Wouldn't this imply that gravitons and higgs bosons come in pairs? Is there any evidence of gravitons and higgs bosons existing only in pairs?
What is the current state of things? Are they fairly confident that the Higgs exist despite more data being needed for the 5-sigma confidence level? Could it still (realistically) turn out to not exist?
I am trying to do some plots for determining the range of higgs mass. Can somebody tell me how to plot higgs mass 'm_h' versus tan β ? or 'm_h' versus spectral index 'n_s' ?
In what sense is the higgs particle expected to be discovered at the LHC?
I mean, the Higgs field has a non-vanishing vacuum expectation value, so it costs no energy to absorb or emit a higgs boson.Hence what is meant when saying that the expected mass is about 126 GeV?
I suppose one is...
Please teach me this:
Does ''Higgs sector'' mean there are many Higgs particle types?Does custodial SU(2) symmetry using mean maybe there is a theory of electroweak interaction more complex than theory of single Higgs scalar?
Thank you in advance.
How can the Higgs boson induce mass?
How can it interact with itself? Is it the only particle able to do so, if yes, why, and if no, what other particles can interact with themselves?
As a side thought, is Young's Double Slit Experiment evidence of particles interacting with themselves (the...
I might misunderstand the higgs mechanism. And I have a puzzle.
Consider an electron in an accelerater. It is massive at low energy and its speed is something lower than the speed of light. However when it is accelerated to the electroweak scale, su(2) becomes unbroken and the electron turns...
Alberto Palma's recent paper Arxiv:1202.0217 says in its conclusions part: "The ATLAS collaboration presents first results of the direct search for the SM Higgs boson decaying to b\bar b. No evidence of the Higgs boson was found in a pp collision data sample of \mathcal L=1.04\ \mathrm f\mathrm...

I am trying to figure out how fast the Higgs decays and how far it travels in a detector at the LHC. Figure 2.5 in http://www.hep.lu.se/atlas/thesis/egede/thesis-node14.html gives decay widths of the Higgs as a function of its mass.
For a Higgs of 125 GeV, it is 0.002 GeV. Using the...
Hi all,
I have few questions regarding Higgs boson and ether model. I wanted to know :-
1.What if "ether" == Higgs Boson?
2.The experiment done earlier to detect ether around the Earth failed because we don't know how to detect that medium?
3. On the question of "Drag" , Please...
With so much coverage in the press over the seemingly imminent discovery of the Higgs particle, there's one question that never seems to get raised - which more than likely means I've missed something fundamentally simple; so this may be a very short thread!
Higgs Boson / Graviton - it may be...
I've recently been told about the higgs boson or "god particle" I've heard it somehow endows particles with their mass, it interacts with the 'larger' (ones with more mass) more than the smaller particles and basically tells them how much mass to have, I am wondering how it does this and also I...
I usually visit this forum as a guest. I am not a physicist but these visits always teach me something and keep me somewhat informed of what goes on in the world of physics. But now I have a question which will probably seem stupid to you all. It is apparent that the Higgs boson plays a most...
Is this the correct form for a Dirac electron in a Higgs field with scalar potential \phi and an electromagnetic field with vector potential A_\mu
i \gamma^\mu \partial_\mu \psi = g \phi \psi + e \gamma_\mu A^\mu \psi
where g is the coupling constant to the Higgs field and e is the...
If most of the mass/energy of a proton is due to the kinetic energy of its quarks and gluons, rather than interaction with the Higgs field, then how can we explain its inertial mass, i.e. its resistance to acceleration, as being due to a drag induced by the Higgs field?
Alternatively imagine...
So I'm trying to understand how the Higgs field and Higgs boson are different from the EM field and the photon. Firstly how I understand the photon is that It is the quanta of energy that an electromagnetic field oscillating at a certain frequency can give to some other system. The photon is the...
In another thread I asked the question if my mass is comprised of "Higgs Mass" and "Kinetic mass".
Drakkith was nice enough to reply best he could, but wasn't certain.
So yea, that's what I am wondering. Is my mass comprised of higgs and kinetic?
125 GeV Higgs and "Vacuum Instability"
So the Higgs has been http://press.web.cern.ch/press/pressreleases/Releases2011/PR25.11E.html (maybe). Nothing "beyond the standard model" about that of course; the Higgs is standard model. Except-- in the leadup to the LHC announcement, I repeatedly saw...
I was thinking if the Higgs part would be found next year, is it true if it could be removed from materials, that you could build spaceships from such materials, you could travel with speeds close to the lightspeed, so Star Track would be a real possibility in the future ?
Or do I forget...
"a sort of cosmic molasses pervading space is what gives particles their heft. Particles trying to wade through it gather mass the way a bill moving though Congress gains riders and amendments, becoming more and more ponderous."
