“…g 2s 2s TrΦ 2s (2.1) where the first two terms come from the N = 2 theory and the third term, W (Φ), can be described as a small perturbation of N = 2 SO(N c ) gauge theory [64,65,66,67,68,69,70,71,72,8,11] W (Φ) = where Φ ab is an adjoint scalar chiral superfield that plays the role of a deformation breaking N = 2 supersymmetry to N = 1 supersymmetry. Note that in [64] the coefficient for the mass term of quark in the tree superpotential is different from √ 2 used here, but it can be absorbed in the mass matrix and the only quadratic mass deformation for Φ with g 2 = µ (other parameters are vanishing) was considered in [64].…”
