1)Does each field have spin and the energy from the spin even if it has no real particle? Such as: electromagnetic (non-zero spin, zero field value with no real particle(=photon)?), gravitational (non-zero spin? zero field value with no real particle?), Higgs (zero spin, non-zero field value? with no real particle), gluon, electron (and other elementary particles) fields etc. 2)What is the (minimum) energy requirement for fermionic field and bosonic field to exist accordingly? Does spin 1/2 field contain more energy than spin 0 field when they contain no real particle with least energy? Does spin 1 field contain more energy than spin 1/2 field? if so how much? twice? Does spin 2 field contain twice more energy than spin 1 field? What determines the minimum energy(=frequency of wave?) required for (ground(least energy) state of) any field? 3)Why photon&gluon must have spin 1 but cannot? have spin 2? why graviton "must" have spin 2 but cannot? have spin 1?
Re: spin value and energy requirement for quantum field?
