CP violating triple product asymmetries in charm decays

Abstract

CP violation asymmetry is expected to be very small within the Standard Model. Observation of CP violation in charm sector would hint towards New Physics. Time-reversal asymmetry is sensitive to CPV via the CPT Theorem, and is a clean and alternative way to search for CP violation in charm decays. This is achieved by the use of triple-product correlations in 4-body charm meson decays. The results from previous searches at BaBar and LHCb Collaborations and the latest results from Belle are reported. The most recent result from Belle performed in D0 ? K+K??+?? decays using kinematic asymmetry variables is the first measurement of its kind. � 2018 Heidelberg University. All rights reserved.
