Complementary C P violation induced by T -odd and T -even correlations

Year: 2025

Type: article

Abstract: In this Letter, we demonstrate that T -odd and T -even correlations, with T representing time reversal, when satisfying specific conditions, result, respectively, in cosine and sine strong phase dependencies of the corresponding C P violation. Additionally, we identify pairs of these C P violation observables in hadron decays depend on precisely the same strong phases within the helicity amplitude scheme. This complementarity could reduce the strong phase reliance in the study of C P violation while also mitigating the risk of suppressed C P violation due to exceptionally small strong phases. Moreover, our proposal holds broad application prospects in further investigating C P violation in baryon decays, which has recently been discovered in the LHCb experiment.
