Measurement of CP Asymmetries in B0 RIGHTWARDS ARROW K0 Sπ0γ Decays at Belle II
Original language description
We report measurements of time-dependent CP asymmetries in B0 RIGHTWARDS ARROW K0Sπ0γ decays based on a datasample of ð388 6Þ x 106 BB- events collected at the ϒð4SÞ resonance with the Belle II detector. The BelleII experiment operates at the SuperKEKB asymmetric-energy eþe- collider. We measure decay-timedistributions to determine CP -violating parameters S and C.We determine these parameters for two rangesof K0Sπ0 invariant mass: mðK0Sπ0Þ ELEMENT OFð0.8; 1.0Þ GeV=c2, which is dominated by B0 RIGHTWARDS ARROW K0ðRIGHTWARDS ARROW K0Sπ0Þγdecays, and a complementary region mðK0Sπ0Þ ELEMENT OFð0.6; 0.8Þ UNION ð1.0; 1.8Þ GeV=c2. Our results haveimproved precision as compared to previous measurements and are consistent with theory predictions.
