Abstract

The first measurement of the effective lifetime of the B¯0s meson in the decay B¯0s→D−sD+s is reported using a proton-proton collision dataset, corresponding to an integrated luminosity of 3 fb−1, collected by the LHCb experiment. The measured value of the B¯0s→D−sD+s effective lifetime is 1.379±0.026±0.017 ps, where the uncertainties are statistical and systematic, respectively. This lifetime translates into a measurement of the decay width of the light B¯0s mass eigenstate of \Gamma_L=0.725±0.014±0.009 ps−1. The B¯0s lifetime is also measured using the flavor-specific B¯0s→D−D+s decay to be 1.52±0.15±0.01ps.
