Description
We report on studies of exclusive dimuon production, using LHCb experimental data. Muon pairs can be exclusively produced by two-photon fusion (a QED process ideally suited to obtaining a precise integrated luminosity measure), or by resonance production. We show results for exclusive dimuon production, and first observations of the exclusive J/Psi, Psi(2S) and Chi_c states, obtained with 37 pb–1 of data at ,-sqrt(s) .= 7 TeV. We compare our cross-section mesasurements to predictions.
