| Özet |
| A measurement of the exclusive two-photon production of muon pairs in proton-proton collisions at√ s= 7 TeV, 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 pT (µ)> 4GeV and pseudorapidity| η (µ)|< 2.1, a fit to the dimuon pT (µ+ µ-) distribution results in a measured cross section of σ (p→ pµ+ µ-p)= 3.38+ 0.58-0.55 (stat.)±0.16 (syst.)±0.14 (lumi.) pb, consistent with the theoretical prediction evaluated with the event generator Lpair. The ratio to the predicted cross section is 0.83+ 0.14-0.13 (stat.)±0.04 (syst.)±0.03 (lumi.). The characteristic distributions of the muon pairs produced via γγ fusion, such as the muon acoplanarity, the muon pair invariant mass and transverse momentum agree with those from the theory. |
