چکیده
The infrared structure of MHV gluon amplitudes in N = 4 super Yang-Mills theory is considered in the next-to-leading order of PT. Explicit cancelation of the infrared divergencies in properly defined cross-sections is demonstrated. The remaining finite parts for some inclusive differential cross-sections are calculated analytically. In general, contrary to the virtual corrections, they do not reveal any simple structure.

The infrared structure of MHV gluon amplitudes in planar limit forN = 4 super YangMills theory is considered in the next-to-leading order of PT. Explicit cancellation of the infrared divergencies in properly defined cross-sections is demonstrated. The remaining finite parts for some inclusive differential cross-sections in planar limit are calculated analytically. In general, contrary to the vi...

We study the Fareytail expansion of the topological partition function of N = 4 SU (N) super Yang-Mills theory on K3. We argue that this expansion corresponds to a sum over geometries in asymptotically AdS 3 spacetime, which is holographically dual to a large number of coincident fundamental heterotic strings.

We study S-duality in N = 4 super Yang-Mills with an arbitrary gauge group by determining the operator product expansion of the circular BPS Wilson and ’t Hooft loop operators. The coefficients in the expansion of an ’t Hooft loop operator for chiral primary operators and the stressenergy tensor are calculated in perturbation theory using the quantum path-integral definition of the ’t Hooft ope...

We have studied the null-plane hamiltonian structure of the free Yang-Mills fields and the scalar chromodynamics (SQCD4). Following the Dirac’s procedure for constrained systems we have performed a detailed analysis of the constraint structure of both models and we give the generalized Dirac brackets for the physical variables. In the free Yang-Mills case, using the correspondence principle in ...
