Search for vector-mediated dark matter at the LHC with forward proton tagging
Abstract
We investigate the production of fermionic dark matter χ via p p →p γ p →p j χ χ ¯X mediated by a leptophobic spin-1 particle, where one of the protons remains intact and is tagged by forward proton detectors. We find that the masses of χ and the mediator Z' are severely constrained when Z' interacts with χ and quarks through the vector couplings. We show that dark matter searches in this production channel are sensitive to a mediator mass mZ'≲1.4 TeV at 14 TeV at the LHC with an integrated luminosity Lint=3000 fb-1. The lower mass bound on the dark matter is mχ≃550 GeV at the mediator mass mZ'=1.2 TeV .
