ChernSimons theory as the largemass limit of topologically massive YangMills theory
Abstract
We study quantum ChernSimons theory as the largemass limit of the limit D→3 of dimensionally regularized topologically massive YangMills theory. This approach can also be interpreted as a BRSinvariant hybrid regularization of ChernSimons theory, consisting of a highercovariant derivative YangMills term plus dimensional regularization. Working in the Landau gauge, we compute radiative corrections up to second order in perturbation theory and show that there is no twoloop correction to the oneloop shift k→ k+ c_{v}, k being the bare ChernSimons parameter. In passing, we also prove by explicit computation that topologically massive YangMills theory is UV finite.
