Measurement of the $X$(3872) mass with first LHCb data
The mass of the $X$(3872) meson is measured using approximately 35 pb$^{-1}$ of data collected with the LHCb detector during the 2010 physics run of the LHC. Inclusively produced $X$(3872) mesons are reconstructed and selected in the $X$(3872) $\to J/\psi \pi^+ \pi^-$, $J/\psi \to \mu^+\mu^-$ decay...
