Based 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 Novikov et al (1980 Nucl. Phys. B 165 67, 1981 Nucl. Phys. B 191 301), 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.

We demonstrate our simple strategy for renormalization with QED at one-loop level, basing on an elaboration of the effective field theory philosophy. No artificial regularization or deformation of

Running’ under tight constraints in pionless effective field theory

The contents of renormalization group invariance and equations under tight constraints are explored and demonstrated with closed-form on-shell $T$ matrices of pionless effective field theory for

Trace and Dilatation Anomalies in Gauge Theories

The form of the anomaly in the trace of the energy-momentum tensor in a general theory of interacting fermions and non-Abelian gauge bosons is derived. The result is shown to involve precisely those

Energy-Momentum-Tensor Trace Anomaly in Spin 1/2 Quantum Electrodynamics

We relate the energy-momentum-tensor trace anomaly in spin-1/2 quantum electrodynamics to the functions ..beta.. (..cap alpha..), delta (..cap alpha..) defined through the Callan-Symanzik equations,

Threshold resummation in momentum space from effective field theory.

Methods from soft-collinear effective theory are used to perform the threshold resummation of Sudakov logarithms for the deep-inelastic structure function F2(x,Q2) in the end-point region x-->1

Direct instantons, topological charge screening, and QCD glueball sum rules

Nonperturbative Wilson coefficients of the operator product expansion (OPE) for the spin-0 glueball correlators are derived and analyzed. A systematic treatment of the direct instanton contributions
