| 英文摘要 | A search for the rare decays b-s(0) -> tau(+) tau(-) and b-0 -> tau(+) tau(-) is performed using proton-proton collision data collected with the lhcb detector. the data sample corresponds to an integrated luminosity of 3 fb(-1) collected in 2011 and 2012. the tau leptons are reconstructed through the decay tau(-) -> pi(-) pi(+)pi(-) nu(tau). assuming no contribution from b-s(0) -> tau(+) tau(-) decays, an upper limit is set on the branching fraction b(b-s(0) -> tau(+) tau(-)) < 6.8 x 10(-3) at the 95% confidence level. if instead no contribution from b-s(0) -> tau(+) tau(-) decays is assumed, the limit is b(b-s(0) -> tau(+) tau(-)) < 2.1 x 10(-3) at the 95% confidence level. these results correspond to the first direct limit on b(b-s(0) -> tau(+) tau(-)) and the world's best limit on b(b-s(0) -> tau(+) tau(-)) |
