First mass measurements at LHCb
We present preliminary mass measurements of the $X(3872)$ particle and five different $b$ hadrons, based on a sample of $pp$ collisions at $\sqrt{s} = 7$ TeV collected in 2010 with the LHCb detector and corresponding to an integrated luminosity of 35 pb$^{-1}$. Signal candidates are fully reconstruc...
