Violation of the Landau-Yang theorem from infrared Lorentz symmetry breaking
Abstract Lorentz symmetry forbids decays of massive spin-1 particle like the Z 0 into two massless photons, a result known as the Landau-Yang theorem. But it is known that infrared effects can break Lorentz invariance. Employing the construction of Mund et al. [1] which incorporated this Lorentz vio...
