Ratios of the light quark masses: Cubic curve vs ellipse
A. A. Osipov
The bounds on the light quark masses are obtained by fitting the squares of pseudoscalar meson masses and to second order in expansion. The result is an alg…
Nambu -- Jona-Lasinio model: , and mesons
A. A. Osipov
We continue to study the properties of the light pseudoscalar nonet within the combined framework of Nambu -- Jona-Lasinio model and expansion, assuming that current quark…
Nambu -- Jona-Lasinio model: Electrically charged and strange pseudoscalars
A. A. Osipov
The mass formulas and decay constants of electrically charged and strange pseudoscalar mesons are analyzed within the combined framework of Nambu -- Jona-Lasinio model and the $1/N…
Proper-time evaluation of the effective action: unequal masses in the loop
A. A. Osipov
The Fock-Schwinger proper-time method is used to derive the effective action in the field theory with the chiral symmetry explicitly broken by unequal masses of h…
approximation and universality of vector mesons
M. K. Volkov, A. A. Osipov, A. A. Pivovarov +1
In this work, we argue that the observed differences in the value of the vector coupling constant extracted from the decays (), () an…
Proper-time method for unequal masses
A. A. Osipov
The result of removing of heavy non-equal mass particles from the theory can be described, at low energy, by the effective action, which is a series in inverse-square powers of the…
