Unparticles and CP-violation

TL;DR

This paper explores how unparticles can induce novel CP-violation effects in B+ decays, providing a unique mechanism consistent with CPT, and highlighting potential new experimental signatures.

Contribution

It introduces a new CP-violation mechanism via unparticles in B+ decays, not predicted by other models, and discusses its consistency with fundamental symmetries.

Findings

Unparticle-induced CP-violation in B+ decays is theoretically viable.

The CP-asymmetry can be significant and experimentally detectable.

The mechanism respects CPT symmetry through a compensating mode.

Abstract

We give a brief summary of the unparticle scenario proposed by Georgi. The CP-even phase of the propagator is exploited to study the CP-asymmetry in B+ --> tau+ + nu, which is neither experimentally searched for nor predicted by any other model. Furthermore we show that the novel CP-violation is consistent with the CPT theorem by identifying the CP-compensating mode in the unparticle sector.
