A general non renormalization theorem in the extended antifield formalism
In the context of algebraic renormalization, the extended antifield formalism is used to derive the general forms of the anomaly consistency condition and of the Callan-Symanzik equation for generic gauge theories. A local version of the latter is used to derive sufficient conditions for the vanishing of beta functions associated to terms whose integrands are invariant only up to a divergence f...
متن کاملClassical and quantum aspects of the extended antifield formalism
Starting from a solution to the classical Batalin-Vilkovisky master equation, an extended solution to an extended master equation is constructed by coupling all the observables, the anomaly candidates and the generators of global symmetries. The construction of the formalism and its applications in the context of the renormalization of generic and potentially anomalous gauge theories are review...
متن کاملCovariant Quantisation in the Antifield Formalism
In this thesis we give an overview of the antifield formalism and show how it must be used to quantise arbitrary gauge theories. The formalism is further developed and illustrated in several examples, including Yang-Mills theory, chiral W3 and W2,5/2 gravity, strings in curved backgrounds and topological field theories. All these models are characterised by their gauge algebra, which can be ope...
متن کاملComments on Unitarity in the Antifield Formalism
It is shown that the local completeness condition introduced in the analysis of the locality of the gauge fixed action in the antifield formalism plays also a key role in the proof of unitarity.
