Instanton Calculus in R-R 3-form Background and Deformed N=2 Super Yang-Mills Theory
Katsushi Ito, Hiroaki Nakajima, Shin Sasaki
We study the ADHM construction of instantons in N=2 supersymmetric Yang-Mills theory deformed in constant Ramond-Ramond (R-R) 3-form field strength background in type IIB superstri…
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…
Instantons in Deformed Super Yang-Mills Theories
Shin Sasaki, Katsushi Ito, Hiroaki Nakajima
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-vol…
Comments on gluon 6-point scattering amplitudes in N=4 SYM at strong coupling
Dumitru Astefanesei, Suguru Dobashi, Katsushi Ito +1
We use the AdS/CFT prescription of Alday and Maldacena \cite{am} to analyze gluon 6-point scattering amplitudes at strong coupling in SYM. By cutting and gluing we obt…
Deformation of Super Yang-Mills Theories in R-R 3-form Background
Katsushi Ito, Hiroaki Nakajima, Shin Sasaki
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 Ram…
Non(anti)commutative N=2 Supersymmetric Gauge Theory from Superstrings in the Graviphoton Background
Katsushi Ito, Shin Sasaki
We study open string amplitudes with the D3-branes in type IIB superstring theory compactified on C^2/Z_2. We introduce constant graviphoton background along the branes and calcula…
