Inclusive\u3c0\ub0 production in 360 GeVpp interactions using the european hybrid spectrometer

The intermediate and forward gamma detectors of EHS are used to reconstruct π°'s produced by 360 GeV/cpp interactions in the Rapid Cycling Bubble Chamber (RCBC). Using the pp forward-backward symmetry, the inclusive π° production cross section is obtained σ <SUB>π°</SUB>=(132±11) mb. The average π° multiplicity is determined as a function of the charged particle multiplicity. The (1-x) dependence is given for different p<SUB>T</SUB> regions

D MESON BRANCHING RATIOS AND HADRONIC CHARM PRODUCTION CROSS-SECTIONS

A determination of branching ratios for D meson decays into all charged particle final states is reported. The values obtained: (D± → K∓π±π±/all D±) = (14 ± 6)% and (D0/D0 → K±π∓π+π-/all D0/D0) = (10 ± 4)%, are higher than those currently accepted. This result, if confirmed, implies a corresponding reduction in the accepted values for some total cross section measurements. Revised inclusive cross sections for D meson production in the forward hemisphere in π-p and pp interactions at 360 GeV/c, are presented. © 1984.0SCOPUS: ar.jinfo:eu-repo/semantics/publishe
