Clothed particle representation in quantum field theory: mass renormalization
The method of unitary clothing transformations is applied in the model involving nucleon and neutral pion fields interacting via the regularized pseudoscalar Yukawa-type coupling. In this approach the mass counterterms are cancelled (at least, partly) by commutators of the generators of clothing tra...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The method of unitary clothing transformations is applied in the model involving nucleon and neutral pion fields interacting via the regularized pseudoscalar Yukawa-type coupling. In this approach the mass counterterms are cancelled (at least, partly) by commutators of the generators of clothing transformations and the field interaction operator forming the pion and nucleon mass shifts expressed through the corresponding three-dimensional integrals whose integrands depend on certain covariant combinations of the relevant three-momenta. The property provides the momentum independence of mass renormalization. The conditions imposed upon the cutoff vertex function are specified. |
