Abstract

Trace anomaly for conformally invariant higher derivative 4D scalar-dilaton theory is obtained by means of calculating divergent part of one-loop effective action for such system. Its applications are briefly mentioned.

Keywords: Quantum field theory; quantum gravity; conformal anomaly.

 

Resumen
