Renormalization of gauge theories and asymptotic freedom of Horava-Lifshitz gravity

Event End:

Event Information:
Using the background-field method we demonstrate the Becchi-Rouet-Stora-Tyutin (BRST) structure of counterterms in a broad class of gauge theories. Put simply, we show that gauge invariance is preserved by renormalization in local gauge field theories whenever they admit a sensible background-field formulation and anomaly-free path integral measure. This class encompasses Yang--Mills theories and relativistic gravity, including both renormalizable and non-renormalizable (effective) theories.
