Aspects of the low-energy constants in the chiral Lagrangian for charmed mesons
Meng-Lin Du, Feng-Kun Guo, Ulf-G. Meißner +1
We investigate the numerical values of the low-energy constants in the chiral effective Lagrangian for the interactions between the charmed mesons and the lightest pseudoscalar mes…
The width of the -resonance at two loop order in baryon chiral perturbation theory
Jambul Gegelia, Ulf-G. Meißner, Dmitrij Siemens +1
We calculate the width of the delta resonance at leading two-loop order in baryon chiral perturbation theory. This gives a correlation between the leading pion-nucleon-delta and pi…
The width of the Roper resonance in baryon chiral perturbation theory
Jambul Gegelia, Ulf-G. Meißner, De-Liang Yao
We calculate the width of the Roper resonance at next-to-leading order in a systematic expansion of baryon chiral perturbation theory with pions, nucleons, and the delta and Roper…
Pion-nucleon scattering in covariant baryon chiral perturbation theory with explicit Delta resonances
De-Liang Yao, D. Siemens, V. Bernard +5
We present the results of a third order calculation of the pion-nucleon scattering amplitude in a chiral effective field theory with pions, nucleons and delta resonances as explici…
