Determining the Higgs spin and parity in the di-photon decay channel using gluon polarization

Abstract

Gluons inside an unpolarized proton are in general linearly polarized. This polarization can, in principle, be used to determine the spin and parity of the newly found Higgs-like boson at the LHC. We focus here on the calculation of the degree of polarization.
