A simultaneous explanation of the large phase in B_s-\bar B_s mixing and B --> \pi\pi / \pi K puzzles in R-parity violating supersymmetry

TL;DR

This paper proposes that specific R-parity violating supersymmetry interactions can simultaneously explain anomalies in B_s mixing phase and B decay puzzles, aligning theory with experimental data.

Contribution

It demonstrates that particular baryon number violating couplings in R-parity violating supersymmetry can account for multiple B meson anomalies.

Findings

R-parity violating couplings can explain large B_s mixing phase.

The model accounts for CP asymmetry differences in B decays.

It predicts larger branching ratios consistent with observations.

Abstract

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 ($> 3.5 \sigma$) between CP-asymmetries in $B^\pm \to \pi^0 K^\pm$ and $B_d \to \pi^\mp K^\pm$ channels, and (iii) a larger than expected branching ratio in $B_d \to \pi^0\pi^0$ channel. We show that selective baryon number violating Yukawa couplings in R-parity violating supersymmetry can reconcile all the measurements.
