Abstract

Using 34.7 pb−1 of data collected with the LHCb detector, the inclusive production of the X(3872) meson in pp collisions at s=7~TeV is observed for the first time. Candidates are selected in the X(3872)→J/ψπ + π − decay mode, and used to measure mX(3872)=387195048 (stat)012 (syst) MeVc2 and m(2S)=368612006 (stat)010 (syst) MeVc2
