D-Meson production from 400 GeV/c pp interactions

Published

Journal Article

We have measured the inclusive production properties of D and D messons produced from pp interactions at s=27.4 GeV. The differential production cross section is well represented by the empirical form d 2 σ dx F dP 2T = 1 2[σ (D/D)(n+1)b](1-|x F |) n exp(-bp 2T ) with n=4.9 ± 0.5, b=(1.0±0.1)(GeV/c) -2 , and the inclusive D/D cross section σ(D/D) is (30.2±3.3) ωb. The QCD fusion model predicts D/D production which is in good agreement with our data except for the magnitude of the cross section which depends sensitively on the assumed mass of the charm quark. © 1987.
