Abstract / Description of output
Exclusive J/ψ and ψ(2S) vector meson production has been observed in the dimuon channel using the LHCb detector. The cross-section times branching fractions to two muons with pseudorapidities between 2.0 and 4.5 are measured to be
σpp→J/ψ(→μ+μ−)(2.0<ημ±<4.5)=307±21±36 pb,
σpp→ψ(2S)(→μ+μ−)(2.0<ημ±<4.5)=7.8±1.3±1.0 pb,
where the first uncertainties are statistical and the second are systematic. The measurements are found to be in good agreement with results from previous experiments and theoretical predictions. The J/ψ photoproduction cross-section has been measured as a function of the photon-proton centre-of-mass energy. The results are consistent with measurements obtained at HERA and confirm a similar power law behaviour for the photoproduction cross-section.
