摘要：

Results on the photoproduction of 10 000 fully reconstructed charmed particles from the 108 recorded triggers of Fermilab experiment E691 have been analyzed in the photon-gluon-fusion model. We find that the total cross section, its rise with energy, and the pT2 and xF distributions can be explained by a high mass for the charm quark (mc=1.74-0.18+0.13 GeV/c2) and a soft-gluon distribution [G(x)(1-x)gn, where ng=7.12.2]. © 1990 The American Physical Society.
