Exclusive γγ → +μμ - production in proton-proton collisions at √s = 7 TeV

Abstract:

A measurement of the exclusive two-photon production of muon pairs in proton-proton collisions at √s = 7TeV, pp → pμ +μ -p, is reported using data corresponding to an integrated luminosity of 40 pb -1. For muon pairs with invariant mass greater than 11:5 GeV, transverse momentum p (μ) > 4 GeV and pseudorapidity σ(μ) < 2:1, a t to the dimuon pT(μ +μ -) distribution results in a measured cross section of η(p → pμ +μ -p) = 3:38 +0:58 0:55 (stat:)±0:16 (syst:)±0:14 (lumi:) pb, consistent wi...
