TWO-PHOTON DECAY OF Z′ AS A PROBE OF BOSE SYMMETRY VIOLATION AT THE CERN LHC

Abstract

The question if the Bose statistics is broken at the TeV scale is discussed. The decay of a new heavy spin-1 gauge boson Z′ into two photons, Z′ → γγ, is forbidden by the Bose statistics among other general principles of quantum field theory (Landau–Yang theorem). We point out that the search for this decay can be effectively used to probe the Bose symmetry violation at the CERN LHC.
