This question is similar to "where is the electromagnetic field?" And the answer is: the electromagnetic field is everywhere; it exists at every point in space-time, but it simply happens that its average value is zero (or close to zero) at points far away from charges, currents, and waves. The Higgs field, like the electromagnetic field, is a quantum ...

Where there is mass, there is Higgs field. It's everywhere in space.

It is small wonder there is no definitive answer to this question here. But I can pass along the best answer I got. I asked the same question, in a slightly different format, to a blog "Of Particular Significance" that is popular with Physics Stack Exchange. My question was whether the famous Goldstone Mexican Hat potential had a value of 245 GeV at the ...

They can't be the same thing. As Wikipedia says, it's possible to calculate certain properties of glueballs from QCD, including their masses, and the masses don't come close to what we've observed for the Higgs boson. Also, the Higgs doesn't have color charge, so it doesn't interact with gluons, whereas a glueball would. That would make a large difference in ...

Let us suppose that that the Standard Model is an effective field theory, valid below a scale $\Lambda$, and that its bare parameters are set at the scale $\Lambda$ by a fundamental, UV-complete theory, maybe string theory. The logarithmic corrections to bare fermion masses if $\Lambda\sim M_P$ is a few percent of their masses. The quadratic correction to ...

From an experimental point of view, there's the problem that the mass of the neutrino is compatible with 0 mass. Having those neutrino really no mass would mean they don't interact with the Higgs Field.

There is no agreement between physicists about neutrino mass generation mechanism. For instance, there is no neutrino mass in Standard Model(SM), because of ambiguity of Higgs mechanism(electron and neutrino_e is SU(2) doublet, and after spontaneous symmetry breaking the first one receives the mass, $m_e$, and second one remains uncoupled. Mechanism of ...

To understand the difference between the Higgs mechanism and the mass generated by a Chern-Simons term one has to realize that the Higgs case is related to a (spontaneously) broken symmetry. Assume that you have written down a field theory which admits a set of equivalent ground states (vacua). These states can be transformed into each other by continuous ...
