TL;DR: In this article, the xF distributions of D+ and D− mesons were investigated at the CERN Ω′ spectrometer, and a clear excess of D− over D+, increasing at high xF, was observed.

TL;DR: In this article, the mass number dependence of charmed mesons was measured and α = 0.92±0.06 for charmed particles with 〈 x F 〉=0.24.

TL;DR: In this article, the decay of K ∗0 (892) mesons has been studied by the hadroproduction experiment WA82, and the ratio of branching ratios, B(D + → K∗0 e + ν e )/B(D+ → K − π + π+ ), is found to be 0.62±0.15± 0.09.
