CPT violation and B-meson oscillations

TL;DR

This paper explores the possibility that observed CP violation in B-meson oscillations could be due to CPT violation, providing the first constraints on CPT violation in the B_s^0 system at an extremely sensitive level.

Contribution

It introduces the first sensitivity analysis of CPT violation in B_s^0 oscillations based on recent CP violation evidence, setting new experimental bounds.

Findings

CPT violation coefficient constrained at parts in 10^{12}

First sensitivity to CPT violation in B_s^0 system

Potential reinterpretation of CP violation in terms of CPT violation

Abstract

Recent evidence for anomalous CP violation in B-meson oscillations can be interpreted as resulting from CPT violation. This yields the first sensitivity to CPT violation in the B_s^0 system, with the relevant coefficient for CPT violation constrained at the level of parts in 10^{12}.
