QCD renormalization in an asymmetric point with massive quarks and Slavnov-Taylor identities

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

We satisfy the Slavnov-Taylor identities of two- and three-point functions in the same momentum configuration, in the first order, with an appropriate choice of the gauge parameter, the asymmetry parameter and the tensorial structure of the vertices. In this way one avoids theg MOM dependence on the vertex chosen to defineg MOM.

Riassunto

Si soddisfano le identità Slavnov-Taylor delle funzioni a due e tre punti nella stessa configurazione dei momenti, nel primo ordine, utilizzando il parametro di gauge, il parametro che caratterizza l'asimmetria del punto di rinormalizzazione e l'arbitrarietà della struttura tensoriale della scomposizione dei vertici. In questo modo si ottiene di svincolare la dipendenza dig MOM dal vertice scelto per definirla.
