Measurement of the $B_s^0$ meson lifetime in $D_s^{+}{\pi }^{-}$ decays

LHCb collaboration, R. Aaij, B. Adeva +698

We present a measurement of the ratio of the Bs meson lifetime, in the flavor-specific decay to $D_s^{+}{\pi }^{-}$, to that of the B0 meson. The pp collision data used correspond to an int…
