Properties of hyperons in chiral perturbation theory
J. Martin Camalich, L. S. Geng, L. Alvarez-Ruso +1
The development of chiral perturbation theory in hyperon phenomenology has been troubled due to power-counting subtleties and to a possible slow convergence. Furthermore, the prese…
SU(3)-breaking corrections to the hyperon vector coupling in covariant baryon chiral perturbation theory
L. S. Geng, J. Martin Camalich, M. J. Vicente Vacas
We report on a recent study of the SU(3)-breaking corrections to the hyperon vector coupling up to in covariant baryon chiral perturbation theory with d…
Dynamically generated resonances
E. Oset, A. Ramos, S. Sarkar +8
In this talk I report on recent work related to the dynamical generation of baryonic resonances, some made up from pseudoscalar meson-baryon, others from vector meson-baryon and a…
SU(3)-breaking corrections to the baryon-octet magnetic moments in chiral perturbation theory
J. Martin Camalich, L. Alvarez-Ruso, L. S. Geng +1
We report a calculation of the baryon magnetic moments using covariant chiral perturbation theory within the extended-on-mass-shell renormalization scheme including intermediate oc…
Leading-order decuplet contributions to the baryon magnetic moments in Chiral Perturbation Theory
L. S. Geng, J. Martin Camalich, M. J. Vicente Vacas
We extend an earlier study of the baryon magnetic moments in chiral perturbation theory by the explicit inclusion of the spin-3/2 decuplet resonances. We find that the corrections…
Dynamically generated resonances from the vector octet-baryon decuplet interaction
Sourav Sarkar, Bao-Xi Sun, E. Oset +1
We study the interaction of the octet of vector mesons with the decuplet of baryons using Lagrangians of the hidden gauge theory for vector interactions. The unitary amplitudes in…
