ArshadQureshi, B.Violation of the Landau-Yang theorem from infrared Lorentz symmetry breakingART-2023-137133Lorentz 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.2023http://zaguan.unizar.es/record/13175410.1007/JHEP10(2023)028http://zaguan.unizar.es/record/131754oai:zaguan.unizar.es:131754info:eu-repo/grantAgreement/ES/DGA-FSE/E21-17Rinfo:eu-repo/grantAgreement/ES/MICINN/PGC2022-126078NB-C21Journal of High Energy Physics 2023, 10 (2023), [9 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
