Measurement of the Bs lifetime difference
A flavour-untagged measurement of the lifetime difference in the $B_s\rightarrow J/\psi \phi$ with $\JPsi \rightarrow \mu ^+ \mu ^-$ and $\phi \rightarrow K ^+ K ^-$ decay is presented. The analyzed dataset corresponds to an integrated luminosity of $5.0\pm0.1~\mbox{fb}^{-1}$ collected in \textrm{pp...
