|a A search for the rare decay D0→μ+μ- is performed using a data sample, corresponding to an integrated luminosity of 0.9fb-1, of pp collisions collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The observed number of events is consistent with the background expectations and corresponds to an upper limit of B(D0→μ+μ-)<6.2(7.6)×10-9 at 90% (95%) confidence level. This result represents an improvement of more than a factor twenty with respect to previous measurements. © 2013 CERN.
