Right-handed new physics remains strangely beautiful

Current data on CP violation in Bd→η'KS and BdphiKS, taken literally, suggest new physics contributions in bs transitions. Despite a claim to the contrary, we point out that right-handed operators with a single weak phase can account for both deviations thanks to the two-fold ambiguity in the extraction of the weak phase from the corresponding CP-asymmetry. This observation is welcome since large mixing in the right-handed sector is favored by many GUT models and frameworks which address the flavor puzzle. There are also interesting correlations with the Bs system which provide a way to test this scenario in the near future.
