Forward cross-sections for production of D+, D0, D/s, D*+ and Lambda/c in 250-GeV pi+-, K+-, and p nucleon interactions.

We measure forward cross sections for production of D+, D0, Ds, D*+, and Λc in collisions of π±, K±, and p on a nuclear target. Production induced by different beam particles is found to be the same within statistics. Strange and baryonic final states are seen to contribute appreciably to the total charm cross section, which our measurements indicate is larger than but consistent with QCD predictions. The energy dependence mapped out by these and previous measurements is consistent with theory. Leading-particle asymmetry measurements for K and p-induced charm production are also presented.

An Experimental Study of the a-Dependence of $J/\psi$ Photoproduction

The Fermilab Tagged Photon Spectrometer collaboration Sokoloff, M.D. ; dos Anjos, J.C.C. ; Appel, J.A. ; et al.
Phys.Rev.Lett. 57 (1986) 3003, 1986.

We have studied the photoproduction of Jψ mesons on H, Be, Fe, and Pb targets using real photons at a mean energy of 120 GeV. The pT2 spectra were used to separate the coherent diffractive signals from the incoherent signals. Parametrizing the per-nucleus cross sections in terms of power-law dependences, Aα, we find that αcoh=1.40±0.06±0.04 for the coherent diffractive signals and αincoh=0.94±0.02±0.03 for the incoherent signals.
