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

Andersson, Bo LU ; Gustafson, Gösta LU and Peterson, Carsten LU (1978) In Physica Scripta 18(4). p.193-195
Abstract

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.
