Angular analysis of the B0 d ! K0 + decay with the ATLAS experiment.
Abstract
An angular analysis of B0
d ! K0(! K+ ��) + �� is presented using 20:3 fb��1 of pp
collision data collected at
p
s = 8 TeV with the ATLAS experiment. The angular
observables FL and S3;4;5;7;8 were extracted in six bins of q2, the invariant mass
squared of the dimuon system, within the full range 0:04 < q2 < 6:00 (GeV=c2)2.
The observables were determined from an unbinned maximum likelihood t using
four folded parameterisations of the full angular distribution. The t results were
used to obtain corresponding values for the optimised observables P1 and P0
4;5;6;8.
The results presented are compatible with Standard Model predictions.
