Abstract: (IOP)

The differential cross-section as a function of rapidity has been measured for the exclusive production of

J/\psi

and

\psi(2S)

mesons in proton-proton collisions at

\sqrt{s}=7

TeV, using data collected by the LHCb experiment, corresponding to an integrated luminosity of 930 pb

^{-1}

. The cross-sections times branching fractions to two muons having pseudorapidities between 2.0 and 4.5 are measured to be

\begin{array}{rl} \sigma_{pp\rightarrow J/\psi\rightarrow{\mu^+}{\mu^-}}(2.0<\eta_{\mu^\pm }<4.5)=&291\pm 7\pm19 {\rm \ pb},\\ \sigma_{pp\rightarrow\psi(2S)\rightarrow{\mu^+}{\mu^-}}(2.0<\eta_{\mu^\pm}<4.5)=&6.5\pm 0.9\pm 0.4 {\rm \ pb},\end{array}

where the first uncertainty is statistical and the second is systematic. The measurements agree with next-to-leading order QCD predictions as well as with models that include saturation effects.
