Higgs boson Definition and 272 Threads

Am i correct when i say that the fermions get a mass and interaction term with the Higgs from the SU(2)_{L}\times U(1)_{Y} invariant Yukawa interaction -g_{y}\bar\psi_{L}\phi\psi_{R} - g_{y}\bar\psi_{R}\bar\phi\psi_{L} where \psi is the fermion field and \phi the Higgs field. My...

We know that - mass bends space-time - this is known as gravity We also know that - (interaction with) Higgs fields gives mass to particles Does mass/gravity bend the Higgs field as well?

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...

Hi all, Has anyone know how to calculate the loop function of Higgs decay to photons/ gluons by t quark , or a useful reference. Cheers, Safinaz

Hello all, How is it that super symmetry accounts for the Higgs having a mass and what would the 4 remaining Higgs bosons account for?

In Zee's "Nutshell QFT" (chapter V.7) or Shifman's book "Avanced Topics in QFT" (section 10) when they talk about vortices, they claim: if \phi(r,\theta) goes to \nuexp( i\theta) as r goes to infinity then \partial_{i}\phi becomes \nu(1/r) I do not see how? Is the phase equal to 1/r if r...

Does the shape of the Higgs potential change if the energy of the vacuum changes? According to Wikipedia, If a more stable vacuum state were able to arise, then existing particles and forces would no longer arise as they presently do. Different particles or forces would arise from (and be...

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?

Hi, I was searching for some example of a theory where all the components of the higgs field are "eaten" by the vector gauge fields and no Higgs boson is left. I have just checked Georgi-Glashow SO(3) --> U(1), but they use a triplet Higgs so at the end again a Higgs Boson does appear. Is it...

[Mentor's note: Several related threads have been combined into this thread.] --------------------------- I read that Electron is mainly energy so it can easily travel through the higgs field. Muon has a bit more mass than Electron so it experiences friction when it goes past the higgs...

Hi, I wonder if a theory like 2HDM has a new triple Higgs coupling, like ##g_{hH^+H^-}##, what governs how much is this coupling ? For example a paper as : arXiv:1405.3584v1 [hep-ph], they normalize ##g_{hH^+H^-}## by the SM ##g_{hWW}##, they plotted at fig. 3 (f)...

Now we are presumably creating (?) Higgs Bosons in the collider. But the universe is permeated already by the Higgs field and Higgs bosons. When the colliders make an "artificial" Higgs, what conservation laws (in addition to energy, momentum, charge, isospin, baryon number etc.)are obeyed? In...

Homework Statement A Higgs boson has mass 125 GeV/c2, decaying into a pair of Z bosons, mass 91 GeV/c2. In the lab frame, one of the Z bosons is at rest. Determine the kinetic energy for the other Z boson in this laboratory frame. Homework Equations E = γmc2 γ=1/√(1-β2) The Attempt at a...

I am looking for the famous CMS and ATLAS papers which announced the discovery of a new boson particle... Could someone help me by posting the link here?

I understand that Higgs mechanism “gives” mass to particles in QM sense. My first question is, why it also gives mass in GR sense, bending space-time? Of course, I don’t expect an answer now as it is definitely a TOE/Quantum gravity territory. However, let me rephrase my question in a narrower...

If the Higgs boson is an excitation in the Higgs field, does that mean that it is exceedingly rare? Do they exist only on earth, or are they also created in high energy places such as quasars? Are the number of Higgs bosons that have existed in the universe on the order of hundreds, billions, or...

http://arxiv.org/abs/1409.0492 Is the Standard Model saved asymptotically by conformal symmetry? A.Gorsky, A.Mironov, A.Morozov, T.N.Tomaras (Submitted on 1 Sep 2014) It is pointed out that the top-quark and Higgs masses and the Higgs VEV satisfy with great accuracy the relations...

Hello. I am an amateur. Is a Higgs boson to the Higgs field the same as an Electron(oops boson)to the electric field? Thx SC

Hi all, I wonder if I study new Higgs scalars, How the data of the LHC for searching for heavier scalars in h-> WW->lvlv and h -> ZZ-> 4 l channels like in [arXiv:1304.0213] can make constrain on my study for the new Higgs? How a figure like figure 2 can give constrains on my model free...

Hello. Since the Higgs Boson is responsible for giving sub-atomic particles mass..or any particles there mass..is there a present understanding of the mechanism by which the field actually does this? And if there is...is there any artificial way of controlling it? My thinking is that if you...

I am not well versed in the idea of Higgs mechanism. However, I was wondering if it does explain the problem of equivalence of gravitational and inertial mass. Also, what is the modern accepted definition of mass?

Hi all, I try to find the detailed calculations of the couplings of sfermions to the lightest h Higgs boson in MSSM, I want to reach Equ. (1.109) in [arXiv:hep-ph/0503173], Do you know any useful reference ? Bests, S.S.

Just as particles move through the theoretical Higgs field and gain energy which gives them mass, do the strings in String theory get their energy to vibrate from the Higgs Field as well? And does that mean that the Strings have mass?

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...

I had an argument at my university about it, since experiments at LHC aren't 100% confirmed. I mean, gauge theories are.. theories and Goldstone bosons are theorems. Someone share some light plese?

In the standard model gravitron is a particle but Higgs boson is not. The Higgs field causes particles to acquire mass. Mass generates a gravitation field. Is gravitron is in any way related to Higgs boson? Is the Higgs field any way related to gravitation field?

Is the Higgs field 4 dimensional?

Reading around gives me some idea of WHY particles interact with the Higgs field but not How! I am looking for a model that I can use to explain the process to my High school students. Can anyone help please. John

Hi everyone, So I've been wondering how much energy does it takes to impart some kind of effect on the higgs field. I've been trying to look for the energy the LHC generates and compare it to the actual amount of energy that it takes for the higgs field to be affected, but since this is all new...

As i understand it, at some point in the early unvierse, the Higgs field was off, then it swtiched on. Is this correct? I can't find when this is supposed to have happened, does anyone know?

if the Higgs bosson field is responsible for giving particles mass. and mass and energy are interchangable e=mc^2. Then is there a field, like the higgs that is responsible for energy. maybe an exited state of the higgs?

I'm a high school student and I don't know much about this stuff e.g. the Higgs Field but i know that the Higgs field gives mass to some particles. I also learned that the mass of an object is relative to its speed. So my question is, what happens to the Higgs field at those near light speeds to...

I'm just looking for a layman's explanation of why the efforts to confirm Higgs was truly necessary and worth the expense. The counter-argument is that theoretical physics seem to be going along just fine assuming something like the Higgs mechanism existed without validating it. Also, nothing...

What i mean is: are there currently Higgs Bosons in the universe or the only place where they exist now is if man (or some other technological being) recreates special conditions like in a particle accelerator? Another related question of mine is: some particles "receive" their mass from the...

It is said that the Higgs field is responsible for the mass of all particles. But the Higgs mechanism provides mass to the gauge bosons, and as far as I know the mass of the fermions is put "by hand" into the Lagrangian. Why, then, is the Higgs field responsible for the mass of the fermions?

Hi all, Have anyone idea about the recent Higgs searches at the LHC ? I mean after finding the SM Higgs , is there now any trials to find another Higgs ? or just now they are confirming and rechecking data, for example if the newly discovered Higgs is the SM one or " SM- like Higgs"...

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...

Greetings, I am brand new to quantum physics. By that I mean I have no idea of the mathematics and know terribly little about the physics. In fact my best background comes from the book QED by Richard Feynman. Anyway, I do know that there are four fundamental forces which have force-carrying...

Newton second law of motion states that acceleration is produced when a force acts on a mass. The Higgs field (mechanism) is the cause of fictitious forces?

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?

Hello dear everyone I would like to ask if someone can help me with the following two things: 1) How many different feynman diagrams can one possibly draw for Higgs strahlung production that is of 4th order? The mediator should be Z-particle. 2) Formulate an equation for the amplitude...

from what I understand, the higgs boson is basically a wave in the higgs field. I understand that they have a lot of mass, but are they hard to create? are there higgs bosons flying past us every time electrons moves through wires, or do they require intense energy to be created?

is the higgs field always homogeneous, or do particles such as electrons cause it to be concentrated about certain points? Are there waves in the higgs field?

Hi, I am drawing Feynman diagrams for various Higgs decay channels. There are two diagrams I am stuck on and there aren't many examples online. They are H→gg and H→Z\gamma For the H→gg decay I had a stab at drawing the reverse of the gluon fusion diagram. Higgs decaying to two gluons via a...

I'm pretty new to quantum mechanics, but I find the idea of a higgs field very interesting. I'm not sure if I understand the phenomenon correctly. I was wondering what happens to the vectors of the field when a photon passes through a point in space. Is the potential of the field disturbed in...

In demonstrating that Higgs mechanism gives mass to gauge boson fields, we used the fact that hypercharge Y=1/2, which is due to "Higgs particle is a complex doublet of the weak isospin SU(2) symmetry". But why? In other words, can you show the details about why the Higgs field has charge...

Hi, please could someone kindly answer a few questions regarding the higgs boson. Everywhere I read about this topic I seem constantly faced with information that is not consistent. I have focused on sources (mainly YouTube videos) of well known physicists and other Physics Forum threads in an...

Any "Practical," Daily Uses for Higgs Field? First of all, my knowledge of the Higgs is limited to pretty much "Science" channel plus scientific related articles on the internet, so forgive any ignorance or misunderstandings. I am interested in potential future applications for the Higgs...

Hello, I'm currently in my last year of high school and I'm doing a project about the higgs particle decaying to two photons. I am using HYPATIA to analyse ATLAS events. When a higgs boson decays into two photons, you can see activity in the electromagnetic calorimeter without seeing a track...
