“…The ultimate test of applicability of the pion exchange model analyzed here or the factorization assumption in the parton model used in references [2,3], should rest on comparison with experiments. For that purpose more precise data are needed than the ones presented in [1].…”

“…This can be simply seen, for example, from the fact that all the considered mesons give zero contribution to the structure function F 3. We can estimate the contribution of the valence quarks by using their distribution [18] and the factorization assumption [2,3]. The result is plotted in Fig.…”

“…Ei ( quark contribution as obtained in [3]. The points with error bars are extracted from experimental results of [1], with the absolute normalization determined from the parton-model result for the inclusive cross-section based on phenomenological distribution functions [ 18] over one angle in the transverse plane is trivial, which reduces the dimensionality of the necessary numerical integration to five.…”

“…The results were interpreted by Ischii et al [2] and Bosveld et al [3] in terms of the patton model, assuming factorization of cross-section into an inclusive piece and a term describing the fragmentation probability of quarks into hadrons. In this way the data could be described qualitatively.…”

Abstract.We analyze the pion-exchange contribution to semi-inclusive leptoproduction on protons, with a slow nucleon or delta in the final state. We calculate the crosssection for slow protons including also the effect of the delta intermediate state, which is the dominant contribution. A comparison with recent experiment shows reasonable agreement for small Bjorken x, if the cut-off in the pion-nucleon-delta form-factor is chosen to be around 0.7 GeV. This substantiates the recent conjecture that sea-quark distributions can be completely associated with the meson cloud, but suggests that the pion-nucleon-delta form-factor should be softer than the one used in description of nuclear forces by meson exchange. We also compare the pion-exchange and the string-fragmentation models and point out possible future experimental tests. PACS" 13.15.Dk; 13.60.Hb

“…Motivated by this experiment, several groups have computed the coincidence cross section for semi-inclusive dis on the proton. It was found [10][11][12] that for small x (x < 0.2), the process is dominated by contributions from sea quarks and/or mesons, and that the valence quarks play only a minor role.…”

Abstract. In this note we explore the consequences of the pion cloud model for semi-inclusive deep inelastic lepton scattering. We argue that by scattering on a few-nucleon target, the detection of the recoiling target would provide a valuable test of the meson cloud model. We estimate the semi-inclusive cross section for deep inelastic lepton scattering on a 3He target, as function of Bjorken x and target recoil momentum.
