Abstract

The azimuthal correlation distribution of 102 charmed-particle pairs observed in the hybrid emulsion experiment WA75 is compared with theoretical predictions. The various pairs - (D^-D⁰), (D^-D⁺), (D⁰D⁰) and (D⁺D⁰)-all s how, within statistical error, the same azimuthal correlation distribution, demonstrating its independence from the specific nature of the production channel. Among the decays of 150 charged charmed particles and 138 neutral ones seen, higher multiplicities are favoured for hadronic as opposed to semileptonic decays. The data are consistent with the muonic decays of charged D mesons proceeding through the channels (μ^±, v, K⁰) and [μ^±, v, K^*0(892)], the fraction through K⁰ being 0.76±0.06.
