N=4 Instanton Calculus in Omega and R-R Backgrounds
Katsushi Ito, Hiroaki Nakajima, Takuya Saka +1
We study the instanton calculus for N=4 super Yang-Mills theory in ten-dimensional Omega-background with the R-symmetry Wilson line gauge field. From the ADHM construction of insta…
N=2 Instanton Effective Action in Omega-background and D3/D(-1)-brane System in R-R Background
Katsushi Ito, Hiroaki Nakajima, Takuya Saka +1
We study the relation between the ADHM construction of instantons in the Omega-background and the fractional D3/D(-1)-branes at the orbifold singularity of C \times C^2/Z_2 in Ramo…
Instanton Calculus in Deformed N=4 Super Yang-Mills Theories
Katsushi Ito, Hiroaki Nakajima, Takuya Saka +1
We study the instanton effective action of four-dimensional deformed N=4 supersymmetric Yang-Mills theory in the presence of constant, self-dual Ramond-Ramond (R-R) 3-form backgrou…
