Description
We study the impact of the inclusion of a light baryonic boson B (which we henceforth refer to as a dark photon), primarily coupled to quarks, as a constituent of the proton; this is achieved by including a dark photon parton distribution function (PDF) in the standard PDF evolution equations. Depending on the proposed mass and coupling of the dark photon, the evolution of light quark and gluon PDFs is distorted to varying degrees. By applying the resulting modified quark and gluon PDFs to high-luminosity high-mass Drell-Yan data, we derive competitive bounds on the mass and coupling of the dark photon.
