Search for the rare decay D0→μ+μ−


LHCb Collaboration; et al; Bernet, R; Müller, K; Steinkamp, O; Straumann, U; Vollhardt, A (2013). Search for the rare decay D0→μ+μ−. Physics Letters B, 725(1-3):15-24.

Abstract

A search for the rare decay D0→μ+μ−is performed using a data sample, corresponding to an integrated luminosity of 0.9 fb−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 \mbox{B(D0→μ+μ−)<6.2(7.6)×10−9} at \mbox{90%} \mbox{(95%)} confidence level. This result represents an improvement of more than a factor twenty with respect to previous measurements.
