Description

We present the di-photon distribution in the decay of an arbitrary spin-0 and spin-2 boson produced from gluon fusion, taking into account the fact that the gluons inside an unpolarized proton are linearly polarized to some extent. The gluon polarization brings about a difference in the transverse momentum distribution of positive and negative parity states. At the same time, it causes the Collins-Soper phi distribution of the photon pair to be non-isotropic for several spin-2 coupling hypotheses, allowing one to distinguish these from the isotropic scalar and pseudoscalar distribution.
