A Comment on the Experimental Determination of $\mathrm{\mid }{V}_{ts}\mathrm{/}{V}_{td}{\mathrm{\mid }}^2$.

We propose a method to extract the ratio $\mathrm{\mid }{V}_{ts}\mathrm{/}{V}_{td}{\mathrm{\mid }}^2$ from a measurement of $\mathrm{\Delta }\mathrm{\Gamma }\mathrm{/}\mathrm{\Gamma }$ for the $B_s$ meson. This method is experimentally more sensitive than the conventional method for large values of $\mathrm{\mid }{V}_{ts}\mathrm{\mid }$ but depends on the accuracy of parton level calculations.
