Measurement of the effective Bs0→K+K− lifetime

LHCb Collaboration

    Research output: Contribution to journalArticlepeer-review


    A measurement of the effective B0s→K+K− lifetime is presented using approximately 37pb−1 of data collected by LHCb during 2010. This quantity can be used to put constraints on contributions from processes beyond the Standard Model in the B0s meson system and is determined by two complementary approaches as τB0s→K+K−=1.440±0.096(stat)±0.008(syst)±0.003(model)ps.
