SUSY R-parity violating contributions to the width differences for $D-\bar{D}$ and $B_{d,s}-{\bar{B}}_{d,s}$ systems

Abstract

We study R-parity violating contributions to the mixing parameter $y$ for $D^0-{\bar{D}}^0$ and $B_{d,s}^0-{\bar{B}}_{d,s}^0$ systems. We first obtain general expressions for new physics contributions to $y$ from effective four fermion operators. We then use them to study R-parity contributions. We find that R-parity violating contributions to $D^0-{\bar{D}}^0$ mixing, and $B_d^0-{\bar{B}}_d^0$ to be small. There may be sizable contribution to $B_s^0-{\bar{B}}_s^0$ mixing. We also obtain some interesting bounds on R-parity violating parameters using known Standard Model predictions and experimental data.
