Renormalization prescriptions in effective theory of pion-nucleon scattering
A. Vereshagin
Using the results presented in the talk by V.Vereshagin (this conference), we illustrate the approach developed in earlier papers by the calculation of (πN) elastic scattering ampl…
Renormalization prescriptions and bootstrap in effective theories
V. Vereshagin, K. Semenov-Tian-Shansky, A. Vereshagin
We discuss the peculiar features of the renormalization procedure in the case of infinite-component effective theory. It is shown that in the case of physically interesting theorie…
Explicit equations for renormalization prescriptions in the case of pion-nucleon scattering
A. Vereshagin
This talk is a natural continuation of that given by V.Vereshagin at this conference. We discuss some details not covered in that talk and review the calculational technique using…
Renormalization programme for effective theories
V. Vereshagin, K. Semenov-Tian-Shansky, A. Vereshagin
We summarize our latest developments in perturbative treating the effective theories of strong interactions. We discuss the principles of constructing the mathematically correct ex…
