eta and eta' hadronic decays in U_L(3)xU_R(3) Chiral Perturbation Theory
Paula Herrera-Siklódy
The decays eta/eta' -> pi pi pi and eta' -> eta pi pi are studied up to leading and next-to-leading order within the framework of U_L(3)xU_R(3) Chiral Perturbation Theory. The anal…
Matching of U_L(3) x U_R(3) and SU_L(3) x SU_R(3) Chiral Perturbation Theories
P. Herrera-Siklódy
The heavy singlet field is integrated out from the U_L(3) x U_R(3) Chiral Perturbation Theory and it is shown how its effects on the low-energy dynamics are reduced to effective ve…
eta-eta' mixing from U_L(3) x U_R(3) Chiral Perturbation Theory
P. Herrera-Siklódy, J. I. Latorre, P. Pascual +1
We obtain explicit expressions for the ηand η' masses and decay constants using U_L(3) x U_R(3) chiral perturbation theory at next-to-leading order in a combined expansion in p^2 a…
Chiral Effective Lagrangian in the large-Nc limit: the nonet case
P. Herrera-Siklódy, J. I. Latorre, P. Pascual +1
A U_L(3) \otimes U_R(3) low-energy effective lagrangian for the nonet of pseudogoldstone bosons that appear in the large-Nc limit of QCD is presented including terms up to four der…
