In order to minimise the impact of hadronic form factor uncertainties, it is useful to introduce ratios with respect to semileptonic $B$ decays [ref] : [equation] where $f_K$ is the kaon decay constant, $V_us$ denotes the corresponding CKM matrix element, and $X_D_s K$ is a calculable quantity governed by phase-space effects.

Since both $B^0_s$ and $B^0_s$ mesons may decay into the same final state $D_s^+K^-$, we obtain CP violation through interference effects between the decay paths that are due to the $B^0_s$–$B^0_s$ oscillations [ref] .
