Keramidas Física, Astronomía y Matemáticas ep scattering c fragmentation Charm cross sections Beauty cross sections Proton structure functions Heavy flavour quarks in ep collisions are produced mostly from pair-production through a fusion of a virtualphoton and a gluon from the proton. Therefore, the production cross sections provide information on the gluondistribution in the proton. The presence of a hard scale from the heavy quark mass, in principle, ensures that thecross sections are calculable through pQCD. Measurements in ep collisions, however, show that the calculationsreasonably agree with the data in general, but underestimate the cross sections in some regions of phase space. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437516 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2C Vol.37 |
