Partition function of N = 2 gauge theories on a squashed S 4 with SU (2)× U (1) isometry

of Results in N = 1 Supersymmetric SU ( 2 ) Gauge Theories

We summarize some results in 4d, N = 1 supersymmetric SU(2) gauge theories: the exact effective superpotentials, the vacuum structure, and the exact effective Abelian couplings for arbitrary bare masses and Yukawa couplings.

SU(N) gauge theories in 2+1 dimensions

We calculate the mass spectra and string tensions of SU(2), SU(3), SU(4) and SU(5) gauge theories in 2+1 dimensions. We do so by simulating the corresponding lattice theories and then extrapolating dimensionless mass ratios to the continuum limit. We find that such mass ratios are, to a first approximation, independent of the number of colours, Nc, and that the remaining dependence can be accur...

SU ( 2 ) × U ( 1 ) Non - anticommutative N = 2 Supersymmetric Gauge Theory 1

We derive the master function governing the component action of the four-dimensional non-anticommutative (NAC) and fully N=2 supersymmetric gauge field theory with a non-simple gauge group U(2) = SU(2) × U(1). We use a Lorentz-singlet NACdeformation parameter and an N=2 supersymmetric star (Moyal) product, which do not break any of the fundamental symmetries of the undeformed N=2 gauge theory. ...

New S - Dualities in N = 2 Supersymmetric SU ( 2 ) x SU ( 2 ) Gauge Theory

New S-dualities in a scale invariant N = 2 gauge theory with SU(2) × SU(2) gauge group are derived from embeddings of the theory in two different larger asymptotically free theories. The true coupling space of the scale invariant theory is a 20-fold identification of the coupling space found in the Mand string-theory derivations of the low energy effective action, implying a larger S-duality gr...
