All-order Finiteness in N = 1 Sym Theories: Criteria and Applications
نویسنده
چکیده
As a motivation, we first recall the possible connection of electric-magnetic duality to finiteness in N = 1 super-Yang-Mills theories (SYM). Then, we present the criterion for all-order finiteness (i.e., vanishing of the β-functions at all orders) in N = 1 SYM. Finally, we apply this finiteness criterion to an SU(5) SGUT. The latter turns out to be all-order finite if one imposes additional symmetries.

Finiteness in N=1 SYM Theories
I present a criterion for all-order finiteness in N =1 SYM theories. Three applications are given; they yield all-order finite N=1 SYM models with global symmetries of the superpotential. 1. INTRODUCTION The aim of this paper is to present applications of the criterion for all-order finiteness in N = 1 SYM of [ 1]. All-order finiteness is here meant in the sense of exact vanishing of the pertur...
متن کاملPerturbative Gravity and Twistor Space
Tree amplitudes in gravity theories can be computed from those of gauge theory using the KLT relations [1]. Inspired by this observation, investigations [2,3,4,5] have been carried out in the hope of discovering a deeper connection at the perturbative level between N = 8 supergravity [6] and N = 4 super Yang-Mills. A link between these theories, beyond structural similarities like the non-abeli...
متن کاملEuclidean SYM Theories By Time Reduction And Special Holonomy Manifolds
Euclidean supersymmetric theories are obtained from Minkowskian theories by performing a reduction in the time direction. This procedure elucidates certain mysterious features of Zumino’s N=2 model in four dimensions, provides manifestly hermitian Euclidean counterparts of all non-mimimal SYM theories, and is also applicable to supergravity theories. We reanalyse the twists of the 4d N=2 and N=...
متن کامل- th ] 2 8 Ju n 20 07 Conformal Invariance = Finiteness and Beta Deformed N = 4 SYM Theory
We claim that if by a choice of the couplings the theory can be made conformally invariant (vanishing of the beta functions) it is automatically finite and vice versa. This is demonstrated by explicit example in supersymmetric gauge theory. The formalism is then applied to the beta deformed N = 4 SYM theory and it is shown that the requirement of conformal invariance = finiteness can be achieve...
متن کاملN = 4 SYM on R × S 3 and Theories with 16 Supercharges
We study N = 4 SYM on R × S3 and theories with 16 supercharges arising as its consistent truncations. These theories include the plane wave matrix model, N = 4 SYM on R× S2 and N = 4 SYM on R× S/Zk, and their gravity duals were studied by Lin and Maldacena. We make a harmonic expansion of the original N = 4 SYM on R×S3 and obtain each of the truncated theories by keeping a part of the Kaluza-Kl...
