| dc.description | Recent data on $B$ meson mixings and decays are, in general, in accord with the standard model expectations, except showing a few hiccups: (i) a large phase in $B_s$ mixing, (ii) a significant difference ($> 3.5 σ$) between CP-asymmetries in $B^\pm \to π^0 K^\pm$ and $B_d \to π^\mp K^\pm$ channels, and (iii) a larger than expected branching ratio in $B_d \to π^0π^0$ channel. We show that selective baryon number violating Yukawa couplings in R-parity violating supersymmetry can reconcile all the measurements. | |
