A surprising relation for the effective coupling constants of N = 2 super Yang-Mills theories

چکیده
We show that the effective coupling constants τ of supersymmetric gauge theories described by hyperelliptic curves do not distinguish between the lattices of the two kinds of heterotic string. In particular, the following relation ΘD+ 16 (τ) = Θ2E8(τ) holds. This is reminiscent of the relation, by T -duality, of the two heterotic strings. We suggest that such a relation extends to all curves describing effective supersymmetric gauge theories.

Deformation of Super Yang-Mills Theories in R-R 3-form Background
We study deformation of N = 2 and N = 4 super Yang-Mills theories, which are obtained as the low-energy effective theories on the (fractional) D3-branes in the presence of constant Ramond-Ramond 3-form background. We calculate the Lagrangian at the second order in the deformation parameter from open string disk amplitudes. In N = 4 case we find that all supersymmetries are broken for generic de...

We study the instanton effective action in deformed four-dimensional N = 2 and N = 4 super Yang-Mills (SYM) theories. These deformed gauge theories are defined on the D-brane world-volume in the presence of constant, self-dual Ramond-Ramond (R-R) 3-form field strength background F which is scaled as (2πα′) 1 2F = fixed in the zero-slope limit α′ → 0. The instanton effective action is obtained b...

متن کاملPerturbative and non-perturbative aspects of pure N = 1 super Yang-Mills theory from wrapped branes
The Maldacena-Nuñez solution is generalized to include a number of integration constants, one of which controls the resolution of the singularity of the wrapped D5-brane background. Some features of the dual pure N = 1 super Yang-Mills (SYM) theory are calculated, amongst which the gluino condensate, the beta function of the gauge coupling and a brane probe potential, which is related to the Ve...
متن کاملTopological Yang Mills and Instantons
By defining an extended BRST operator that includes the chiral part of N=2 global supersymmetry, it is shown that the full N=2 offshell Super Yang Mills Action can be represented as an exact BRST term. The action written in this form suggests that the fields of the Topological Yang Mills theory can be defined in terms of composite fields of supersymmetry ghosts and N=2 fields in a natural way. ...
