Forward-proton-tagged photon-induced production of a leptophobic Z' mediator would exclude mZ' below about 1.4 TeV at 14 TeV and 3000 fb^-1, with a dark matter mass bound near 550 GeV for the vector benchmark.

abstract
The exclusive production pp->pXp is known to be one of the most clean channels at the LHC. We investigate the potential of processes pp -> p l-l+ p and pp-> p gamma gamma p to probe scalar and tensor unparticles by considering three different forward detector acceptances; 0.0015<xi<0.15, 0.0015<xi<0.5 and 0.1<xi<0.5. We obtain 95% confidence level sensitivity limits on the unparticle couplings for various integrated luminosities.

Search for Vector-mediated Dark Matter at the LHC with Forward Proton Tagging
Forward-proton-tagged photon-induced production of a leptophobic Z' mediator would exclude mZ' below about 1.4 TeV at 14 TeV and 3000 fb^-1, with a dark matter mass bound near 550 GeV for the vector benchmark.
