Effective Gauge Degrees of Freedom and the (Non)existence of the Glueball Superpotential
نویسنده
چکیده
We propose an efficient way to obtain a correct Veneziano-Yankielowicz type integration constant of the effective glueball superpotential Weff (S, g,Λ), even for massless theories. Applying our method, we show some N = 1 theories do not have such an effective glueball superpotential, even though they have isolated vacua. In these cases, S = 0 typically.

The Glueball Superpotential for G 2
We perform a perturbative computation of the glueball superpotential for N = 1 supersymmetric G2 gauge theory with one adjoint matter multiplet. We find that the computation simplifies because the bosonic momentum integral cancels with the fermionic momentum integral. The effective glueball superpotential allows us to gain an insight into non-perturbative aspect of the supersymmetric gauge theory.
متن کامل2 00 4 Extending the Veneziano - Yankielowicz Effective Theory
We extend the Veneziano Yankielowicz (VY) effective theory in order to account for ordinary glueball states. We propose a new form of the superpotential including a chiral superfield for the glueball degrees of freedom. When integrating it “out” we obtain the VY superpotential while the N vacua of the theory naturally emerge. This fact has a counterpart in the Dijkgraaf and Vafa geometric appro...

متن کاملEffective superpotential for U(N) with antisymmetric matter
We consider an N = 1 U(N) gauge theory with matter in the antisymmetric representation and its conjugate, with a tree level superpotential containing at least quartic interactions for these fields. We obtain the effective glueball superpotential in the classically unbroken case, and show that it has a non-trivial N -dependence which does not factorize. We also recover additional contributions s...
