Nonperturbative region of effective strong coupling
Viktor V. Andreev
In the framework of Poincaré covariant quark model the behavior of running coupling constant is considered in $Q < 1 \mbox{GeV}$ region. An analysis was c…

About one method of analytical calculations of reaction amplitudes with fermions
V. V. Andreev
The paper presents the new method of calculations of reaction amplitudes of processes with spin 1/2 fermions. The method is based on the application of isotropic tetrad in Minkowsk…
