Phenomenological relations between large-pT meson spectra
1978 (English)In: Physical Review D. Particles and fields, ISSN 0556-2821, E-ISSN 1089-4918, Vol. 18, no 11, p. 4144-4151Article in journal (Refereed) Published
Abstract [en]

Recent data on the hadron ratios π+π-, K+π+, K-π-, and ηπ0 at large transverse momenta are shown to be consistent with predictions from a simple phenomenological two-component picture for large-pT production. The very-large-pT part of meson spectra is assumed to be dominated by particles that contain one of the incoming valence quarks, while small-and medium-pT mesons are built up mostly of quarks created in quark-antiquark pairs. Exceptions are K- and φ spectra, where for obvious reasons the very-large-pT component is missing. Simple relations between π, K, and η spectra are found. Predictions for the large-pT spectrum of φ mesons are presented.
