What we have learned from direct CP violation studies in kaon decays
A. A. Belkov, G. Bohm, A. V. Lanyov
A self-consistent analysis of K --> 2pi and K --> 3pi decays within a unique framework of chiral dynamics applied to the QCD-corrected weak nonleptonic quark lagrangian has been pe…
SIMUB -- a Monte Carlo Generator for Physics Simulation of B Decays
A. Belkov, S. Shulga
We present the SIMUB package developed at Dubna for MC generation of B meson production and decays. The starting version of the package includes lepton modes of B decays, in partic…
An Effective Chiral Meson Lagrangian at from the NJL Model
A. A. Bel'kov, A. V. Lanyov, A. Schaale +1
In this work we present a strong chiral meson Lagrangian up to and including in the momentum expansion. It is derived from the Nambu--Jona-Lasinio (NJL) model using the he…
Chiral Meson Lagrangians from the QCD Based NJL Model Modified by Nonlocal Effects
A. A. Bel'kov, A. V. Lanyov, A. Schaale +1
Starting from a QCD inspired bilocal quark interaction we obtain a local effective meson lagrangian. In contrast to previous local (NJL-like) approaches, we include nonlocal correc…
Reduction of Vector and Axial--Vector Fields in a Bosonized Nambu--Jona--Lasinio Model
A. A. Bel'kov, A. V. Lanyov, A. Schaale
We derive the effective action for pseudoscalar mesons by integrating out vector and axial--vector collective fields in the generating functional of the bosonized NJL--model. The c…
