Photon collider search strategy for sleptons and dark matter at the LHC

Abstract

We propose a search strategy using the LHC as a photon collider to open sensitivity to scalar lepton (slepton $\tilde{\ell }$) production with masses around 15 to 60 GeV above that of neutralino dark matter ${\tilde{\chi }}_1^0$. This region is favored by relic abundance and muon $(g-2{)}_{\mu }$ arguments. However, conventional searches are hindered by the irreducible diboson background. We overcome this obstruction by measuring initial state kinematics and the missing momentum four-vector in proton-tagged ultraperipheral collisions using forward detectors. We demonstrate sensitivity beyond LEP for slepton masses of up to 220 GeV for $15\lesssim \Delta m(\tilde{\ell },{\tilde{\chi }}_1^0)\lesssim 60$ GeV with 100 fb${}^{-1}$ of 13 TeV proton collisions. We encourage the LHC collaborations to open this forward frontier for discovering new physics.
