We consider a non-anticommutative N=2 superspace with an SU(2) singlet and Lorentz scalar deformation parameter, ${theta^{alpha i},theta^{beta j}}_star = -2iP e^{alphabeta}e^{ij}$. We exploit this unique feature of the N=2 case to construct a deformation of the non-Abelian super-Yang-Mills theory which preserves the full N=2 supersymmetry together with the SU(2) R symmetry and Lorentz invariance. The resulting action describes a kind of heterotic special geometry with antiholomorphic prepotential $bar f(barphi) = Tr (barphi^2 (1+Pbarphi)^{-2})$.
We find a formulation of $mathcal{N}=2$ supersymmetric Yang-Mills theory in Projective superspace. In particular we find an expression for the field strength in terms of an unconstrained prepotential which is desirable when quantizing the theory. We
The N=2* Super-Yang-Mills theory (SYM*) undergoes an infinite sequence of large-N quantum phase transitions. We compute expectation values of Wilson loops in k-symmetric and antisymmetric representations of the SU(N) gauge group in this theory and sh
This is a sequel of our paper hep-th/0606125 in which we have studied the {cal N}=1 SU(N) SYM theory obtained as a marginal deformation of the {cal N}=4 theory, with a complex deformation parameter beta and in the planar limit. There we have addresse
We study event shapes in N=4 SYM describing the angular distribution of energy and R-charge in the final states created by the simplest half-BPS scalar operator. Applying the approach developed in the companion paper arXiv:1309.0769, we compute these
We construct the D3-brane solution in the holographic dual of the N = 2* theory that describes Wilson lines in symmetric representations of the gauge group. The results perfectly agree with the direct field-theory predictions based on localization.
