英文摘要Using a data set corresponding to an integrated luminosity of 3fb(-1), collected by the lhcb experiment in ppcollisions at centre-of-mass energies of 7 and 8tev, the effective lifetime in the b-s(0) -> j/psi eta decay mode, teff, is measured to be tau(eff) = 1.479 +/- 0.034 (stat)+/- 0.011 (syst) ps. assuming cp conservation, tau(eff) corresponds to the lifetime of the light b-s(0) mass eigenstate. this is the first measurement of the effective lifetime in this decay mode.
