B mixing at LEP
Recent results from LEP on mixing in the $B$ sector are reviewed. The new LEP $95\%$ CL lower limit on $B_s$ mixing of $\Delta m_s > 9.5~{\rm ps^{-1}}$ combined with the LEP average for $\Delta m_d$ of $0.469 \pm 0.017~{\rm ps^{-1}}$, starts to significantly constrain the unitarity triangle for t...
