Abstract
A search for the decays Bs0âμ+μâ and B0âμ+μâ is performed with 0.37 fbâ1 of pp collisions at s=7 TeV collected by the LHCb experiment in 2011. The upper limits on the branching fractions are B(Bs0âμ+μâ)<1.6Ã10â8 and B(B0âμ+μâ)<3.6Ã10â9 at 95% confidence level. A combination of these results with the LHCb limits obtained with the 2010 dataset leads to B(Bs0âμ+μâ)<1.4Ã10â8 and B(B0âμ+μâ)<3.2Ã10â9 at 95% confidence level.
