Quark-model hadron structure
We review some selected recent results on hadron spectroscopy and related theoretical studies based on constituent quark models.
متن کاملHadron Structure Functions in a Chiral Quark Model
The strong interaction contributions to the cross–sections in deep inelastic scattering are parameterized by the hadronic tensor Wμν . The associated form factors depend on the Lorentz–scalars Q = −q2 and x = Q/2p · q, with p and q being the momenta of the nucleon and the exchanged photon, respectively. The most convincing evidence for the quark–substructure of the nucleon stems from the so– ca...
متن کاملHadron Structure Functions within a Chiral Quark Model
We outline a consistent regularization procedure to compute hadron structure functions within bosonized chiral quark models. We impose the Pauli–Villars scheme, which reproduces the chiral anomaly, to regularize the bosonized action. We derive the Compton amplitude from this action and utilize the Bjorken limit to extract structure functions that are consistent with the scaling laws and sum rul...
متن کاملHadron-Hadron Scattering in the Nonrelativistic Quark Model
In this HADRON2001 contribution we summarize the status of our quark-model calculations of hadron-hadron scattering amplitudes in annihilation-free channels. The predictions are in reasonably good agreement with experimentally known S-wave meson-meson and meson-baryon phase shifts, and there are very recent indications that S-wave πω scattering (extracted from FSIs in b1 decay) may also be simi...
