Exclusive J /ψ and ψ(2 S ) production in pp collisions at √s = 7 TeV
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)(...
