Renormalization of gauge invariant operators and anomalies in Yang-Mills theory
G. Barnich, M. Henneaux
A long-standing conjecture on the structure of renormalized, gauge invariant, integrated operators of arbitrary dimension in Yang-Mills theory is established. The general solution…
Perturbative Gauge Anomalies in the Hamiltonian Formalism: A Cohomological Analysis
G. Barnich
The quantum action principle of renormalisation theory is applied to the antibracket-antifield formalism for Hamiltonian systems. General results on the local BRST cohomology allow…
Consistent Interactions between Gauge Fields and Local BRST Cohomology : The Example of Yang-Mills Models
G. Barnich, M. Henneaux, R. Tatar
Recent results on the cohomological reformulation of the problem of consistent interactions between gauge fields are illustrated in the case of the Yang-Mills models. By evaluating…
Consistent couplings between fields with a gauge freedom and deformations of the master equation
G. Barnich, M. Henneaux
The antibracket in BRST theory is known to define a map associating with two equivalence classes of BRST invariant observables of re…
