Unpolarized fragmentation function for the pion and kaon via the nonlocal chiral-quark model
arXiv:1109.0357 · doi:10.1007/s00601-012-0347-9
Abstract
In this talk we present our recent studies for the unpolarized fragmentation functions for the pion and kaon, employing the nonlocal chiral quark model, which manifests the nonlocal interaction between the quarks and pseudoscalar mesons, in the light-cone frame. It turns out that the nonlocal interaction produces considerable differences in comparison to typical local-interaction models.
