decay in the Nambu - Jona-Lasinio model
A. A. Osipov
Within the context of an extended Nambu - Jona-Lasinio model, we analyze the role of the axial-vector and mesons in the decay . The contribut…
Gauge covariant approach to the electroweak interactions of mesons in the Nambu-Jona-Lasinio model with spin-1 states
A. A. Osipov, B. Hiller, P. M. Zhang
An extended Nambu-Jona-Lasinio (NJL) model with chiral group and spin-0 and spin-1 four quark interactions is used to develop the gauge covariant approach to the…
Hadronic electroweak current and mixing
A. A. Osipov, B. Hiller, P. M. Zhang
It is found that in presence of electroweak interactions the gauge covariant diagonalization of the axial-vector -- pseudoscalar mixing in the effective meson Lagrangian leads to a…
Electromagnetic interactions of mesons induced by the axial-vector -- pseudoscalar mixings
A. A. Osipov, M. M. Khalifa
It is shown that the diagonalization of the axial-vector -- pseudoscalar transitions in the effective meson Lagrangian in presence of electromagnetic interactions leads to a deviat…
Thermodynamical properties of strongly interacting matter in a model with explicit chiral symmetry breaking interactions
J. Moreira, J. Morais, B. Hiller +2
We analyse the effects of the light and strange current quark masses on the phase diagram of QCD at finite temperature and vanishing baryonic chemical potential, computing the spee…
Anomalous decay in the Nambu - Jona-Lasinio model
A. A. Osipov, M. K. Volkov
Using the Nambu--Jona-Lasinio model with the chiral symmetric effective four-quark interactions, we derive the amplitude of the radiative decay $f_1(1285) \toπ^+π…
