Measurement of the ¯B0s→D−sD+s and ¯B0s→D−D+s effective lifetimes
The first measurement of the effective lifetime of the ¯B0s meson in the decay ¯B0s→D−sD+s is reported using a proton-proton collision data set, corresponding to an integrated luminosity of 3 fb−1, collected by the LHCb experiment. The measured value of the ¯B0s→D−sD+s effective lifetime is 1.379±0....

| Zusammenfassung: | The first measurement of the effective lifetime of the ¯B0s meson in the decay ¯B0s→D−sD+s is reported using a proton-proton collision data set, corresponding to an integrated luminosity of 3 fb−1, collected by the LHCb experiment. The measured value of the ¯B0s→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 ¯B0s mass eigenstate of ΓL=0.725±0.014±0.009 ps−1. The ¯B0s lifetime is also measured using the flavor-specific ¯B0s→D−D+s decay to be 1.52±0.15±0.01 ps. |
