LHC searches for Dark Matter in compressed mass scenarios: challenges in the forward proton mode

Popis výsledku v původním jazyce

We analyze in detail the LHC prospects at √s = 14 TeV for charged electroweakino searches, decaying to leptons, in compressed supersymmetry scenarios, via exclusive photon-initiated pair production. This provides a potentially increased sensitivity in comparison to inclusive channels. We pay attention to the challenges that such searches would face in the high pile-up environment of the LHC, giving close consideration to the backgrounds. The signal we focus on is the exclusive production of same-flavour muon and electron pairs, with missing energy in the final state, and with two outgoing intact protons registered by the dedicated forward proton detectors. We present results for slepton masses of 120–300 GeV and slepton-neutralino mass splitting of 10–20 GeV, and find that the relevant backgrounds can be controlled to the level of the expected signal yields. We also outline a range of potential methods to further suppress these backgrounds as well as to enlarge the signal yields.
