Te. Browder et S. Pakvasa, REMARK ON THE EXPERIMENTAL-DETERMINATION OF VERTICAL-BAR-V-TS V-TD-VERTICAL-BAR(2)/, Physical review. D. Particles and fields, 52(5), 1995, pp. 3123-3124
We propose a method to extract the ratio /V-ts/V-td/(2) from a measure
ment of Delta Gamma/Gamma for the B-s meson. This method is experiment
ally more sensitive than the conventional method for large values of /
V-ts/ but depends on the accuracy of parton level calculations.
