New RG fixed points and duality in supersymmetric SP(Nc) and SO(Nc) gauge theories Original Research Article

We present evidence for new, non-trivial RG fixed points with dual magnetic descriptions in N = 1 supersymmetric SP(Nc) and SO(Nc) gauge theories. The SP(Nc) case involves matter X in the antisymmetric tensor representation and Nf flavors of quarks Q in the fundamental representation. The SO(Nc) case involves matter X in the symmetric tensor representation and Nf flavors of quarks Q in the vector representation of SO(Nc). Perturbing these theories by superpotentials W(X), we find a variety of interesting RG fixed points with dual descriptions. The duality in these theories is similar to that found by Kutasov and by Kutasov and Schwimmer in SU(Nc) with adjoint X and Nf quarks in the fundamental.
