Baryon Chiral Perturbation Theory combined with the Expansion in SU(3) I: Framework
Ishara P. Fernando, Jose L. Goity
Baryon Chiral Perturbation Theory combined with the expansion is implemented for three flavors. Baryon masses, vector charges and axial vector couplings are studied to one-…
Nucleon and Delta axial-vector couplings in 1/Nc - Baryon Chiral Perturbation Theory
A. Calle Cordon, J. L. Goity
In this contribution, baryon axial-vector couplings are studied in the framework of the combined 1/Nc and chiral expansions. This framework is implemented on the basis of the emerg…
Baryon Masses and Axial Couplings in the Combined 1/Nc and Chiral Expansions
A. Calle Cordon, J. L. Goity
The effective theory for baryons with combined 1/Nc and chiral expansions is analyzed for non-strange baryons. Results for baryon masses and axial couplings are obtained in the sma…
Partial Decay Widths of Negative Parity Baryons in the 1/Nc Expansion
C. Jayalath, J. L. Goity, E. Gonzalez de Urreta +1
The partial decay widths of lowest lying negative parity baryons belonging to the 70-plet of SU(6) are analyzed in the framework of the 1/Nc expansion The channels considered are t…
Electromagnetic two-body currents of one- and two-pion range
S. Pastore, R. Schiavilla, J. L. Goity
Nuclear electromagnetic currents are derived in time-ordered perturbation theory within an effective-field-theory framework including explicit nucleons, isobars, and pions up t…
Electromagnetic Processes in EFT
S. Pastore, R. Schiavilla, J. L. Goity
Nuclear electromagnetic currents derived in a chiral-effective-field-theory framework including explicit nucleons, isobars, and pions up to NLO, {\it i.e.} ignoring loop co…
