# Questions about the Higg's Field

Why do some particles interact more strongly with the Higgs field than others, while some particles like the photon do not interact at all? Is there a Higgs number assigned to all particles?

• Please ask only one question per post, unless the questions are so closely related they make no sense on their own. For the questions themselves: 1. What do you mean by the Higgs field being "uniform"? Quantum fields do not have a definite value, and there is no meaningfully observable classical field corresponding to it. 2. Why do you think that a particles mass increasesas a function of its velocity "through the Higgs field"? 3. Actually a well-defined question, unless you get too philosophical about the meaning of "why". If the question asked just this it would be answerable. – ACuriousMind Apr 26 '19 at 22:11
• Just an comment; (1) Is not the direct "interaction" with Higg's Field $\phi$ that generates masses, but the Higg's field VEV; (2) See en.wikipedia.org/wiki/Mass_in_special_relativity – user164843 Apr 26 '19 at 22:21
• @ACuriousMind - If a particle's speed through the Higg's Field does not increase it's mass, what causes the mass increase as you approach C? – Rick Apr 26 '19 at 22:47
• The "mass" the Higgs mechanism produces is not the same "mass" that increases when things go faster. See e.g. physics.stackexchange.com/q/133376/50583 – ACuriousMind Apr 26 '19 at 22:53
• @ACuriousMind - there shortened it for you – Rick Apr 27 '19 at 23:48
