摘要：
The recent measurements of the B mass difference Delta M-s by the CDF and DO collaborations are roughly consistent with the Standard Model predictions, therefore, these measurements will afford an opportunity to constrain new physics scenarios beyond the Standard Model. We consider the impact of the R-parity violating supersymmetry in the B-s(0)-(B) over bar (0)(s) mixing, and use the latest experimental results of Delta M-s to constrain the size of the R-parity violating tree level couplings in the B-s(0)-(B) over bar (0)(s) mixing. Then, using the constrained RPV parameter space from Delta M-s, we show the R-parity violating effects on the B-s width difference Delta Gamma(s).
