Indication of anomalous exchange in exclusive charmonium photoproduction
A. Sibirtsev, S. Krewald, A. W. Thomas
We find that available data on photoproduction at 1 GeV are energy independent over the range GeV and show a very soft dependence. Thr…
Physical Baryon Resonance Spectroscopy from Lattice QCD
D. Morel, B. Crouch, D. B. Leinweber +1
We complement recent advances in the calculation of the masses of excited baryons in quenched lattice QCD with finite-range regulated chiral effective field theory enabling contact…
Charmonium photoproduction
A. Sibirtsev, S. Krewald, A. W. Thomas
The available data on photoproduction are analyzed in terms of pomeron exchange, two gluon exchange and photon-gluon fusion models. Allowing the pomeron-quark interaction to…
Medium modification of the nucleon axial form factor
D. H. Lu, A. W. Thomas, K. Tsushima
We study the modification of the nucleon axial form factor in nuclear matter. The internal quark substructure of the nucleon is self-consistently described by the quark meson coupl…
On the to ratio from proton-proton collisions
A. Sibirtsev, K. Tsushima, W. Cassing +1
We compare the recent COSY data on the total and cross sections with the predictions from two boson exchange models that either are based solely…
A quark-meson coupling model with short-range quark-quark correlations
K. Saito, K. Tsushima, A. W. Thomas
Short-range quark-quark correlations are introduced into the quark-meson coupling (QMC) model in a simple way. The effect of these correlations on the structure of the nucleon in d…
