Observation of Ds1(2536)+ -> D+ pi- K+
Abstract
We report the observation of the decay Ds1(2536)+ -> D+ pi- K+. We also measure the helicity angle distributions in the decay Ds1(2536)->D*+ K0S and thus constrain the contributions and the phase difference of D and S wave amplitudes in this decay. The results are based on a 281 fb-1 data sample collected with the Belle detector near the Y(4S) resonance, at the KEKB asymmetric energy e+e- collider.
