This higgs field breaks electroweak symmetry and provides mass to particles though a process called the higgs mechanism. The excitation of the higgs field is called a higgs boson.

do Higgs Bosons happen in nature all the time? Rarely? Or do they only happen when the Higgs field is excited in a particle accelerator?
I'm trying to reconcile an apparent contradiction between explanations given by Dr. Cox in 2009 and 2012, and those given by a panel of Berkeley professors.
I'm not a physicist, and so I realize this contradiction is likely my layman…

What's the relationship between weakly hypercharged bosons and Higgs bosons?
In this video, Leonard Susskind does a good job trying to explain succinctly the Higgs field and exactly how it gives elementary fermions mass, except for one point he seems to skip a few things. The weak hypercharge is endearingly called 'zilch'…

Does field energy create rest mass in QFT theories?
The central importance of Higgs boson would be that the Higgs mechanism gives rest mass to fundamental particles. It seems like a very natural argument that fundamental particles need to be given rest mass by a field interaction because as…

Practical matter of the Higgs-Mechanism
My maybe very naive question is, of what practical importance will the discovery of the Higgs-Mechanism be for our technological advance in the near future?

Difference between Higgs contribution to electroweak boson mass, and fermion mass?
Thanks in advance to anyone who takes the time to answer this, and apologies in advance for what is probably (yet another) question here due to unfamiliarity with The Math.
I had a chance recently to visit the CMS detector at CERN (sheer luck) and…

Turning off or tuning the Higgs field
What would happen to the Universe if we turned off the Higgs field?
(Remark: "turning off the Higgs field" means to set its v.e.v. to zero-today its value is about 246 GeV.)
Would the Z,W bosons be massive?
Would atoms form?
Would vacuum energy be…

Could one theoretically build the Higgs equivalent of a Faraday cage?
My understanding is, within quantum mechanics, in a pure vacuum, all known fields have a lowest energy state of zero. The Higgs field is the only exception -- it's lowest energy state is not zero. Hence, the uniform field permeating all of space,…

Please explain me how the Higgs boson gives mass to other particles, more detail?
As we know, the Higgs boson gives mass to other particles. But here is onething which is not clear for me. I mean, I do not understand how the Higgs boson gives mass to other particles? Does anyone could explain me more explicitly how procedure goes…

Can one measure the Higgs field?
Can one measure the Higgs field? Or is the higgs field not measurable?
I know that the higgs boson is a indication for the presence of the higgs field. But it is the only way of the presence of the higgs field?
When the higgs field is not…

Higgs boson/field symmetries and local symmetries
In the SM with gauge group U(1)xSU(2)xSU(3), those factors are associated to the gauge bosons associated with a local symmetry and the Higgs field provides masses to the elementary fermions AND the W,Z bosons (the photon is inert) through SSB. My…

Does the Higgs boson (or the 125 GeV boson, if it's not exactly the Higgs as predicted) occur in nature?
If the Higgs boson mediates mass interactions, do they exist in nature? Are there Higgs bosons flying around all the time? Or do they only exist for a tiny fraction of a second while they mediate mass?
As I understand it, the bosons are all…

One-loop Higgs mass in the Standard Model
I cannot reproduce the one-loop Higgs mass expression with a cutoff regularization.
The standard result found in literature is (which leads to the so-called Veltman condition):
\begin{equation}\delta m_h^2 = \frac{3\Lambda^2}{16\pi^2…

What stabilizes the Higgs field components against rotation?
As known, the Higgs field has a 4-th grad "Mexican hat" potential, described by the formula $\nu = -\mu\phi^*\phi+\lambda(\phi^*\phi)^2$:
Where $\phi$ are the 4-vector of the components of the Higgs field and $\mu$ and $\lambda$ are constant real…

Higgs field - the vacuum expectation value
I have already asked questions about the Higgs mechanism. But what still interests me is the following: The vacuum expectation value of the Higgs field is responsible for the emergence of the elementary particle masses, together with the Yukawa…

In Standard Model, are both the Higgs doublet and its complex conjugate present in the universe, or not the complex conjugate one?
In Standard Model, the Higgs doublet is \begin{equation}
\Phi=\left(\begin{array}{c}\phi^+\\ \phi^0\end{array}\right)
=\frac{1}{\sqrt{2}}\left(\begin{array}{c}
\phi_1+i\phi_2\\
\phi_3+i\phi_4
\end{array}\right)
\end{equation}
The complex conjugate…
