DOIAbstract
Results of fitting the differential distributions in xF and pT2 of D mesons produced in 400 GeV/c p-p interactions to the form View the MathML source are discussed. The D+ distribution is found to be relatively hard [n=3.1\ub10.8\u3008Pt2\u3009=1.32\ub10.27 (GeV/c)2] and the D\u3040 distribution relatively soft [n=8.1\ub11.9,\u3008pT2\u3009=0.62\ub10.14 (GeV/c)2] compared to the average for all D's [n=4.9\ub10.5,\u3008pT2\u3009=0.99\ub10.10 (GeV/c)2]. It is suggested that these distributions could reflect contribution of leading di-quarks in pp collisions. Comparison is made with evidence for leading quarks in charm production in 360 GeV/c\u3c0 12p interactions
