The large CP phase in B(s)-anti-B(s) mixing from primary scalar unparticles

TL;DR

This paper investigates how primary scalar unparticles could influence B(d,s) mixing, especially considering recent hints of new physics in the B(s) mixing phase, and constrains unparticle parameters accordingly.

Contribution

It introduces the impact of primary scalar unparticles on B(d,s) mixing and derives bounds on their couplings based on recent experimental data.

Findings

Allowed parameter space for unparticle couplings identified

Constraints on unparticle contributions to B(s) mixing phase

Implications for new physics in flavor mixing

Abstract

In this letter we consider the case of primary scalar unparticle contributions to B(d,s) mixing. With particular emphasis on the impact of the recent hint of new physics in the measurement of the B(s) mixing phase, phi(s), we determine the allowed parameter space and impose bounds on the unparticle couplings.
