$b$-hadron lifetime measurements with exclusive $b\to J/\psi X$ decays reconstructed in the 2010 data
We report on absolute lifetime measurements in the exclusive decays $B^+ \to J/\psi K^+$, $B^0 \to J/\psi K^{*0}$, $B^0 \to J/\psi K_S$, $B_s^0 \to J/\psi \phi$ and $\Lambda_b \to J/\psi \Lambda$ using 36$pb^{-1}$ of data collected in 2010 with the LHCb detector and a muon trigger at a centre-of-mas...
