Massive quarks and large transverse momenta I One-particle inclusive scattering

For pt.I see abstr. A54325 of 1973. The massive quark model is applied to one-particle inclusive cross sections at large p/sub T/. The author computes several different contributions, all characterized by power laws with different 'indices' and scaling functions. One of these contributions...

description For pt.I see abstr. A54325 of 1973. The massive quark model is applied to one-particle inclusive cross sections at large p/sub T/. The author computes several different contributions, all characterized by power laws with different 'indices' and scaling functions. One of these contributions exhibits the p/sub T//sup -4/ scaling behaviour, but it appears to dominate only at very high s(s>10/sup 4/ GeV/sup 2/) and for very small values of omega /sub 1/ and omega /sub 2/. For lower values of s and small omega /sub 1,2/ one gets a p/sub T//sup -8/ behaviour for mesons with p/sub T//sup -10/ for baryons, while for larger values of omega /sub 1,2/ one finds that the contribution with n=5 dominates. A discussion of particle yields, multiplicities and structure of final states is also given. (11 refs).
