Trek : The One - Loop N = 4 Noncommutative SYM Action
We investigate N = 4 noncommutative super Yang-Mills (SYM) theory. We compute the one-loop four gauge boson scattering amplitude on parallel Dp-branes, and find the corresponding contribution to the noncommutative SYM one-loop action in a momentum expansion. The result is somewhat surprising. We find that while the planar diagram can be written using the usual ∗-product, the contributions from ...
متن کاملConstruction of one - loop N = 4 SYM effective action in the harmonic superspace approach
We develop a systematic approach to construct the one-loop N = 4 SYM effective action depending on both N = 2 vector multiplet and hypermultiplet background fields. Beginning with the formulation of N = 4 SYM theory in terms of N = 2 harmonic superfields, we construct the one-loop effective action using the covariant N = 2 harmonic supergraphs and calculate it in N = 2 harmonic superfield form ...
متن کاملSupergravitons from One Loop Perturbative N = 4 Sym
We determine the partition function of 1 16 BPS operators in N = 4 SYM at weak coupling at the one-loop level in the planar limit. This partition function is significantly different from the one computed at zero coupling. We find that it coincides precisely with the partition function of a gas of 1 16 BPS ‘supergravitons’ in AdS5 × S . e-mail: [email protected] e-mail: [email protected]

متن کاملAnatomy of One - Loop Effective Action in Noncommutative Scalar Field Theories 1
One-loop effective action of noncommutative scalar field theory with cubic self-interaction is studied. Utilizing worldline formulation, both planar and nonplanar parts of the effective action are computed explicitly. We find complete agreement of the result with Seiberg-Witten limit of string worldsheet computation and standard Feynman diagrammatics. We prove that, at lowenergy and large nonco...
