We study the sensitivity of the High-Luminosity LHC to a light baryonic dark photon B, primarily coupled to quarks, and demonstrate its potential in determining competitive bounds on dark photon parameter space by analyzing its effect on the tails of Drell-Yan invariant mass distributions.
We study the sensitivity of the High-Luminosity LHC to a light baryonic dark photon B, primarily coupled to quarks, as a constituent of the proton. This is achieved by allowing for a dark photon parton distribution function (PDF) in the PDF evolution equations. Depending on the mass and coupling of the dark photon, the evolution of standard quark and gluon PDFs is distorted to varying degrees. By analysing the effect of the dark photon on the tails of Drell-Yan invariant mass distributions, we demonstrate the potential of the LHC in determining competitive bounds on dark photon parameter space.
