Multiplicative Renormalization of Yang-Mills Theory in BPST-Instanton Background

摘要

Pure Euclidean SU(2) Yang-Mills theory in the background of the BPST-instanton configuration is considered. Using the behaviour of the classical (three) Lagrangian under BRS-transformations, ''ghost'' field dilatations and the so-called type-1 transformations, the method of Becchi, Rouet and Stora is applied to show multiplicative renormalizability of the theory. As a by-product, the most general tree Lagrangian satisfying the Slavnov identities is obtained. (Atomindex citation 16:069141)
