Superconformal Anomaly from AdS/CFT Correspondence
M. Chaichian, W. F. Chen
For a classical superconformal gauge theory in a conformal supergravity background, its chiral R-symmetry anomaly, Weyl anomaly and super-Weyl anomaly constitute a supermultiplet.…
Symmetry Origin of Infrared Divergence Cancellation in Topologically Massive Yang-Mills Theory
W. F. Chen
We manifestly verify that the miraculous cancellation of the infrared divergence of the topologically massive Yang-Mills theory in the Landau gauge is completely determined by a ne…
Effects of Trilinear Term in Softly Broken N=1 Supersymmetric QCD
M. Chaichian, W. F. Chen, T. Kobayashi
Softly broken dual magnetic theory of N=1 supersymmetric SU(N_c) QCD with N_f flavours is investigated with the inclusion of trilinear coupling term of scalar fields in the case of…
A Down to Earth Attempt at Determining the Low Energy Effective Action of N=2 Supersymmetric Yang-Mills Theory
M. Chaichian, W. F. Chen, C. Montonen
We review a detailed investigation of the perturbative part of the low-energy effective action of N=2 supersymmetric Yang-Mills theory in a conventional effective field theory appr…
