Using Linear Gluon Polarization Inside an Unpolarized Proton to Determine the Higgs Spin and Parity

Abstract

Gluons inside an unpolarized proton are in general linearly polarized in the direction of their transverse momentum, rendering the LHC effectively a polarized gluon collider. This polarization can be utilized in the determination of the spin and parity of the newly found Higgs-like boson. We focus here on the determination of the spin using the azimuthal Collins–Soper angle \({\phi}\) distribution.
