Is there a non-standard-model contribution in non-leptonic b to s decays?
Martin Jung
TL;DR
This paper examines potential non-Standard Model contributions to non-leptonic b to s decays by analyzing discrepancies in high-precision flavour observables and their implications for New Physics operators.
Contribution
It provides a detailed analysis of tensions in B decay channels and constrains possible New Physics operators beyond the Standard Model.
Findings
Identifies specific tensions in B to J/psi K, phi K, and pi K decays.
Deduces constraints on (bs)(qq) type New Physics operators.
Highlights potential non-Standard Model effects in flavour observables.
Abstract
The data on high-precision flavour observables reveal certain puzzles when compared to Standard Model expectations based on a global fit of the CKM unitarity triangle and general theoretical estimates. The discussion of these tensions in the channels B to J/psi K, B to phi K, and B to pi K, and the deduced constraints for New Physics operators of the class (bs)(qq) form the content of this talk.
