Abstract
Recent measurements of rising ratios of resonance to back-ground with Feynmanx of various particle combinations in inclusive reactions seem to point against the quark recombination model. We show, for the proton fragmentation region and for the case ρ0/(π+π-) that a) ρ0-resonance production is well reproduced by the recombination model up tox ≅ — 0.2,b) for the (π+π-) nonresonant background due to kinematical reasons one of the pions is slow in most cases forxπ+π-≳ 0.8 and the recombination model-suited only for the fragmentation region ofboth pions- cannot be applied to such a configuration, c) for a reasonable empirical extrapolation of the joint two-pion distribution to lowx of the background pions the rising resonance/background ratio can be Well reproduced. We conclude that the data are hardly suited to test the recombination model.
