The Chern-Simons Coefficient in Supersymmetric Yang-Mills Chern-Simons Theories
We study one-loop correction to the Chern-Simons coefficient κ = k/4π in N = 1, 2, 3 supersymmetric Yang-Mills Chern-Simons systems. In the pure bosonic case, the shift of the parameter k is known to be k → k + c v , where c v is the quadratic Casimir of the gauge group. In the N = 1 case, the fermionic contribution cancels the bosonic contribution by half and the shift is k → k + c v /2, makin...
متن کاملSupersymmetric Yang-Mills-Chern-Simons theory
The supersymmetric regularization of gauge theories remains a major unsolved problem in supersymmetry. In this contribution we consider supersymmetric Yang-Mills-Chern-Simons theory in three dimensions and prove that ordinary dimensional regularization (or DReG) [1] and regularization by dimensional reduction (or DReD) [2] preserve both supersymmetry and BRS invariance. We further show that the...
متن کاملYang-mills-chern-simons Supergravity
N = (1, 0) supergravity in six dimensions admits AdS3 × S 3 as a vacuum solution. We extend our recent results presented in hep-th/0212323, by obtaining the complete N = 4 Yang-Mills-Chern-Simons supergravity in D = 3, up to quartic fermion terms, by S3 group manifold reduction of the six dimensional theory. The SU(2) gauge fields have Yang-Mills kinetic terms as well as topological Chern-Simon...
متن کاملThe Chern-Simons Coefficient in Supersymmetric Non-Abelian Chern-Simons Higgs Theories
By taking into account the effect of the would be Chern-Simons term, we calculate the quantum correction to the Chern-Simons coefficient in supersymmetric Chern-Simons Higgs theories with matter fields in the fundamental representation of SU(n). Because of supersymmetry, the corrections in the symmetric and Higgs phases are identical. In particular, the correction is vanishing for N = 3 supersy...
متن کاملZero-mode dynamics in supersymmetric Yang-Mills-Chern-Simons theory
We consider minimally supersymmetric Yang-Mills theory with a Chern-Simons term on a flat spatial two-torus in the limit when the torus becomes small. The zero modes of the fields then decouple from the nonzero modes and give rise to a spectrum of states with energies that are given by multiples of the square of the coupling constant. We discuss the determination of this low-energy spectrum, bo...
