Title: Polarization test of Higgs spin and parity

Photon polarization measurements provide a model independent determination of the spin and the parity of the Higgs resonance. The test described here is based on very general principles and is completely independent of dynamical assumptions. A set of observables are identified that discriminate resonances with J{sup P} = 0{sup +}, 0{sup −}, 2{sup −} and 2{sup +}. Furthermore, the same set can be used to gain useful and important information on the magnitude of each helicity amplitude contributing to the gg → γγ process.
