Universidad de Zaragoza (orcid)0000-0003-3669-6241 Violation of the Landau-Yang theorem from infrared Lorentz symmetry breaking 2023 Access copy available to the general public Unrestricted Lorentz symmetry forbids decays of massive spin-1 particle like the Z0 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 violation, we propose an interaction leading to the decay Z0→ 2γ and study the dependence of the decay on the parameter of this Lorentz violation. info:eu-repo/grantAgreement/ES/DGA-FSE/E21-17R info:eu-repo/grantAgreement/ES/MICINN/PGC2022-126078NB-C21 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 5.0 2023 PHYSICS, PARTICLES & FIELDS 6 / 31 = 0.194 2023 Q1 T1 0.832 2023 Nuclear and High Energy Physics 2023 Q2 10.0 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Balachandran, A.
