arXiv:hep-th/0701015 · doi:10.1088/1751-8113/40/36/016
Abstract
Basing on some new and concise forms of the Callan-Symanzik equations, the low-energy theorems involving trace anomalies à la Novikov-Shifman-Vainshtein-Zakharov, first advanced and proved in Nucl. Phys. \textbf{B165}, 67 (1980), \textbf{B191}, 301 (1981), are proved as immediate consequences. The proof is valid in any consistent effective field theories and these low-energy theorems are hence generalized. Some brief discussions about related topics are given.
