- Abstract
- Using 462 fb(-1) of e(+)e(-) annihilation data recorded by the Belle detector, we report the first observation of the decay D-s1(2536)(+)-> D+pi K--(+). The ratio of branching fractions B(D-s1(2536)(+)-> D+pi K--(+))/B(D-s1(2536)(+)-> D*K-+(0)) is measured to be (3.27 +/- 0.18 +/- 0.37)%. We also study the angular distributions in the D-s1(2536)(+)-> D*K-+(S)0 decay and measure the ratio of D- and S-wave amplitudes. The S-wave dominates, with a partial width of Gamma(S)/Gamma(total)=0.72 +/- 0.05 +/- 0.01.
