Measurement of the CP-violating asymmetries in B0→K0sπ0 and of the branching fraction B0→K0π0

We present a measurement of the time-dependent C P -violating asymmetries in B 0 → K 0 S π 0 decays based on 383 × 10 6 Υ ( 4 S ) → B ¯¯¯ B events collected by the BABAR experiment at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center. We measure the direct C P -violati...
