Low-P/sub T/ hadron production and a valon-parton recombination model

A variant of the recombination model which we call the valon-parton model is applied simultaneously to a variety of meson inclusive reactions with proton, pion and kaon beams in the kinematic region of low transverse momentum and intermediate values of longitudinal momentum fractions. It is found that the valon distributions in hadrons show no evidence for SU(3) breaking. There are some indications of substantial gluon dissociation contributions which we interpreted through a maximally enhanced sea. For proton induced reactions the model predictions are in excellent agreement with the data; meson initiated reactions indicate additional contributions are coming from resonances which are produced recombinantly and then decay into the observed mesons
