Subleading-color contributions to gluon-gluon scattering in N=4 SYM theory and relations to N=8 supergravity
Stephen G. Naculich, Horatiu Nastase, Howard J. Schnitzer
We study the subleading-color (nonplanar) contributions to the four-gluon scattering amplitudes in N=4 supersymmetric SU(N) Yang-Mills theory. Using the formalisms of Catani and of…
Two-loop graviton scattering relation and IR behavior in N=8 supergravity
Stephen G. Naculich, Horatiu Nastase, Howard J. Schnitzer
We derive an ABDK-like relation between the one- and two-loop four-graviton amplitudes in N=8 supergravity. Specifically we show that the infrared divergent part of the two-loop am…
Introduction to AdS-CFT
Horatiu Nastase
These lectures present an introduction to AdS-CFT, and are intended both for begining and more advanced graduate students, which are familiar with quantum field theory and have a w…
Gluon scattering in Super Yang-Mills at finite temperature
Katsushi Ito, Horatiu Nastase, Koh Iwasaki
We extend the AdS/CFT prescription of Alday and Maldacena to finite temperature , defining the amplitude for gluon scattering in Super Yang-Mills at strong coupling…
D=4 Einstein gravity from higher D CS and BI gravity and an alternative to dimensional reduction
Horatiu Nastase
An alternative to usual dimensional reduction for gravity is analyzed, in the vielbein-spin connection formulation. Usual 4d Einstein gravity plus a topological term (the "Born-Inf…
A "black hole" solution of scalar field theory
Horatiu Nastase
A black hole-like solution to a toy model scalar field action for the pion is presented. It has a "horizon" that traps pion field information (it cannot escape in finite time) and…
