Measurements of absolute branching fractions of D0 ? KL0 ?, KL0 ?, KL0 ?, and KL0 ??

Abstract

Abstract: We report the first measurements of the absolute branching fractions of D0?KL0?, D0?KL0?, D0?KL0?, and D0?KL0??, by analyzing 2.93 fb-1 of e+e- collision data taken at a center-of-mass energy of 3.773 GeV with the BESIII detector. Taking the world averages of the branching fractions of D0?KS0?, D0?KS0?, D0?KS0?, and D0?KS0??, the KS0-KL0 asymmetries R(D0,X) in these decay modes are obtained. The CP asymmetries in these decays are also determined. No significant CP violation is observed. © 2022 authors. Published by the American Physical Society.
