Implications of a large vector meson production on quark jet fragmentation and large p _T reactions

Summary, in English

A large vector meson production in quark jet fragmentation implies characteristic differences between the kaon and pion spectra. This prediction is verified in a recent SLAC-MIT experiment. Similar considerations are relevant for the c-quark fragmentation into D-mesons, as observed in ν scattering experiments.The difference in kaon and pion spectra provides a test of the hard quark-quark scattering description of large p _T events. In particular the K⁺/π⁺ ratio (∼ 1/2 for single particle triggers) should be around 0.1-0.2 for jet triggers.
