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…
Radiative Kaon Decays and Violation
A. A. Bel'kov, A. V. Lanyov, A. Schaale
The amplitudes of and decays have been calculated within chiral Lagrangian approach including higher-order derivative t…
On the Origin of the Enhancementof CP-violating Charge Asymmetries in Decays Predicted from Chiral Theory
A. A. Bel'kov, G. Bohm, D. Ebert +2
We present an analysis of the enhancement of CP-violating charge asymmetries in decays. Calculations of decay amplitudes are performed on the basis of bosonized…
Heat-Kernel Calculation of Quark Determinant and Computer Algebra
A. A. Bel'kov, D. Ebert, A. V. Lanyov +1
In this paper there we describe the calculational background of deriving a strong meson Lagrangian from the Nambu--Jona-Lasinio quark model using the computer algebra systems FORM…
