TTP97-21 CP Violation in $B_s$ Decays

CP-violating effects in non-leptonic $B_s$-meson decays are reviewed. Special emphasis is given to implications arising from the width difference $\Delta\Gamma_s$ between the $B_s$ mass eigenstates. If $\Delta\Gamma_s$ is found to be sizable, certain untagged $B_s$-meson decays may allow interesting probes of CP violation, extractions of the CKM angle $\gamma$ and the Wolfenstein parameter $\eta$, and may indicate physics beyond the Standard Model.
