Measurement of CP asymmetries in B0 → K0SK0SK0S decays

# metadata.dc.description.abstract[].value
We present measurements of the time-dependent C P -violating asymmetries in B 0 → K 0 S K 0 S K 0 S decays based on 384 × 10 6 Υ ( 4 S ) → B ¯¯¯ B decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We obtain the C P asymmetry parameters C = 0.02 ± 0.21 ± 0.05 and S = − 0.71 ± 0.24 ± 0.04 , where the first uncertainties are statistical and the second systematic. These results are consistent with standard model expectations.
