The role of P-wave inelasticity in J/psi to pi+pi-pi0
Peng Guo, Ryan Mitchell, Adam P. Szczepaniak
We discuss the importance of inelasticity in the P-wave pi pi amplitude on the Dalitz distribution of 3pi events in J/psi decay. The inelasticity, which becomes sizable for pi pi m…
P-wave pi pi amplitude from dispersion relations
Adam P. Szczepaniak, Peng Guo, Marco Battaglieri +1
We solve the dispersion relation for the P-wave pi pi amplitude.We discuss the role of the left hand cut vs Castillejo-Dalitz-Dyson (CDD), pole contribution and compare the solutio…
Quark-nucleon dynamics and Deep Virtual Compton Scattering
M. Gorchtein, A. P. Szczepaniak
We consider deeply virtual Compton scattering and deep inelastic scattering in presence of Regge exchanges that are part of the non-perturbative quark-nucleon amplitude. In particu…
A model for QCD ground state with magnetic disorder
Adam P. Szczepaniak, Hrayr H. Matevosyan
We explore an ansatz for the QCD vacuum in the Coulomb gauge that describes gauge field fluctuations in presence of a weakly interacting gas of abelian monopoles. Such magnetic dis…
