Elastic pion-nucleon scattering in chiral perturbation theory: Explicit (1232) degrees of freedom
Dmitrij Siemens
For the first time, elastic pion-nucleon scattering is analyzed in the framework of chiral perturbation theory up to fourth order with explicit degrees of freedom. The analysis…
Elastic and inelastic pion-nucleon scattering to fourth order in chiral perturbation theory
D. Siemens, V. Bernard, E. Epelbaum +3
We extend our previous study of elastic pion-nucleon scattering in the framework of chiral perturbation theory by performing a combined analysis of the reactions and $π…
Reconciling threshold and subthreshold expansions for pion-nucleon scattering
D. Siemens, J. Ruiz de Elvira, E. Epelbaum +4
Heavy-baryon chiral perturbation theory (ChPT) at one loop fails in relating the pion-nucleon amplitude in the physical region and for subthreshold kinematics due to loop effects e…
Elastic pion-nucleon scattering in chiral perturbation theory: A fresh look
D. Siemens, V. Bernard, E. Epelbaum +3
Elastic pion-nucleon scattering is analyzed in the framework of chiral perturbation theory up to fourth order within the heavy-baryon expansion and a covariant approach based on an…
The reaction pi N -> pi pi N in chiral effective field theory with explicit Delta(1232) degrees of freedom
D. Siemens, V. Bernard, E. Epelbaum +2
The reaction pi N -> pi pi N is studied at tree level up to next-to-leading order in the framework of manifestly covariant baryon chiral perturbation theory with explicit Delta(123…
