Does the Higgs field give mass to particles unrelated to it? All particles with mass or some particles? Does the Higgs boson as such play a role in giving mass to other particles, or is the boson just a feature (excitation?) of the Higgs field? Can the Higgs boson be reasonably described as a mediator of the field, e.g. when giving mass to particles (mediator of that action)? Thank you.
