Observation of proton-tagged, central (semi)exclusive production of high-mass lepton pairs in pp collisions at 13 TeV with the CMS-TOTEM precision proton spectrometer
The process pp → p ℓ + ℓ -p(*), with ℓ + ℓ - a muon or an electron pair produced at midrapidity with mass larger than 110 GeV, has been observed for the first...
