    • This paper is the first part of a program to deal with the relative importance of the different effects in a colour dipole field when the field energy is transformed into hadrons according to a statistical scheme with the sole constraints coming from energy and momentum conservation and the requirements of scaling. In this paper we treat the meson distributions from quark fragmentation with particular emphasis on the importance of a vector meson production of the size observed at present. We neglect diquark formation and the baryon distributions as a first approximation. The simplicity of the approach will make it possible to easily understand the size and the shape of the different contributions.

  • Implications of a large vector meson production on quark jet fragmentation and large p T reactions
  • 1978
  • In: Physica Scripta. - : IOP Publishing. - 0031-8949 .- 1402-4896. ; 18:4, s. 193-195
  • Journal article (peer-reviewed)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.
