During the 2011 proton=-proton run LHCb recorded a luminosity of 1 fb<sup>−1</sup>

a centrecenter-of-mass energy of 7 TeV. In 2012 2 fb<sup>−1</sup> was collected at 8 TeV.<ref>[http://lpc.web.cern.ch/lpc/lumiplots_2012.htm], 2012 LHC Luminosity Plots</ref> These datasets allow to carry out the baseline physics program of the experiment of precision Standard Model tests and led to evidence for the [[Flavor-changing neutral current|flavour changing neutral current]] decay B<sub>s</sub> → μ μ.<ref>[http://arxiv.org/abs/1211.2674], Arxiv: First evidence for the decay Bs → μ+ μ-</ref> The latter measurement impacts the parameter space of Supersymmetry.
