Neutrino trident production may offer powerful probe of new physics

(Phys.org) --The standard model (SM) of particle physics has four types of force carrier particles: photons, W and Z bosons, and gluons. But recently there has been renewed interest in the question of whether there might exist a new force, which, if confirmed, would result in an extension of the SM. Theoretically, the new force would be carried by a new gauge boson called Z' or the "dark photon" because this "dark force" would be difficult to detect, as it would affect only neutrinos and unstabl...
