Abstract
| A search for the very rare decays B,-+ µ+ µ-and B0-+ µ + µ-has been performed using 1.0 fb-1 integrated luminosity of pp collisions at ys = 7 TeV collected by the LHCb experiment at LHC during the year 2011. Stringent limits has been imposed on the upper branching fractions: B(B-+ µ-+ µ-) < 4.5 (3.8) x 10-9 and B(B0-+ µ + µ-) < 1.0 (0.81) x 10-9 at 953 (903) confidence level. |
