On non - commutative N = 2 super Yang - Mills

چکیده
We discuss the Seiberg-Witten solution of the non-commutative N = 2 U(N) SYM model. The solution is described in terms of the ordinary Seiberg-Witten curve of the SU(N) theory plus an additional free U(1). Hence, at the two-derivative approximation the theory flows to the ordinary commutative theory in the infra-red (k < 1/ √ θ). In particular, the center U(1) is free and it decouples from the other U(1)′s. In addition, no UV/IR mixing is found.

On the thermodynamics of large N non - commutative super Yang - Mills theory
We study the thermodynamics of the large N non-commutative super Yang-Mills theory in the strong ’t Hooft coupling limit in the spirit of AdS/CFT correspondence. Although the thermodynamic quantities of nearextremal D3-branes with NS B fields, which are dual gravity configurations of the non-commutative N = 4 super Yang-Mills theory, are the same as those without B fields, there are some differ...
متن کاملSuper Yang-Mills Theory from a Supermatrix Model
It is known that Yang-Mills theories on non-commutative space can be derived from largeN reduced models. Gauge fields in non-commutative Yang-Mills theories can be described as fluctuations of matrices expanded about an appropriate classical solution of the reduced models. We investigate a generalization of this procedure in superfield formalism. We show that we can construct a supermatrix mode...
متن کاملChiral-Yang-Mills theory, non commutative differential geometry, and the need for a Lie super-algebra
In Yang-Mills theory, the charges of the left and right massless Fermions are independent of each other. We propose a new paradigm where we remove this freedom and densify the algebraic structure of Yang-Mills theory by integrating the scalar Higgs field into a new gauge-chiral 1-form which connects Fermions of opposite chiralities. Using the Bianchi identity, we prove that the corresponding co...
متن کاملString Junction from Non-Commutative Super Yang-Mills Theory
We construct a 1/4 BPS soliton solution in N = 4 non-commutative super YangMills theory to the first order in the non-commutativity parameter θij . We then solve the non-commutative eigenvalue equations for the scalar fields. The CallanMaldacena interpretation of the eigenvalues precisely reproduces the expected string junction picture: the string junction is tilted against the D3-branes with a...
متن کاملA Note on Interactions of (Non-Commutative) Instantons Via AdS/CFT
We consider the interaction between instantons and anti-instantons in four-dimensional N = 4 super-Yang–Mills theory at large N and large ’t Hooft coupling as described by D-instantons via AdS/CFT duality. We give an estimate of the strength of the interaction in various regimes. We discuss also the case of Non-Commutative super-Yang–Mills theory where the interaction between instantons and ant...
