The existence of "bosons" is already a consequence of QM -- the notion of indistinguishable particles and the resulting Bose-Einstein (as opposed to Maxwell-Boltzmann) statistics is manifestly not a classical phenomena. Classical particles are always distinguishable, since "that particle there" has a complete set of observables that classically commute with ...

Not sure. Completely lost about the equations. However, have you seen the experiment in which electrons that pass through one slit are rotated by 2 pi. The interference pattern shifts. The min and maximum flip. I'm not exactly sure why an electron that is in different state would show any kind of interference pattern at all. In any case the experiment might ...

One very general statement is that if you take one of the external momenta to zero, keeping the other momenta fixed, the amplitude will vanish. This is simply a consequence of the non-linear (shift) symmetry acting on the Goldstone bosons. This symmetry implies that they can enter the effective Lagrangian only with derivative couplings. Since the derivative ...
