Abstract
A search for the rare decays B0
s ! þ and B0 ! þ is performed in pp collisions at ffiffi
s
p ¼
7 TeV, with a data sample corresponding to an integrated luminosity of 1:14 fb 1, collected by the CMS
experiment at the LHC. In both cases, the number of events observed after all selection requirements is
consistent with expectations from background and standard-model signal predictions. The resulting upper
limits on the branching fractions are BðB0
s ! þ Þ < 1:9 10 8 and BðB0 ! þ Þ < 4:6 10 9,
at 95% confidence level.
