Instantons in N=1/2 Super Yang-Mills Theory via Deformed Super ADHM Construction
Takeo Araki, Tatsuhiko Takashima, Satoshi Watamura
We study an extension of the ADHM construction to give deformed anti-self-dual (ASD) instantons in N=1/2 super Yang-Mills theory with U(n) gauge group. First we extend the exterior…
On A Superfield Extension of The ADHM Construction and N=1 Super Instantons
Takeo Araki, Tatsuhiko Takashima, Satoshi Watamura
We give a superfield extension of the ADHM construction for the Euclidean theory obtained by Wick rotation from the Lorentzian four dimensional N=1 super Yang-Mills theory. In part…
Non(anti)commutative N=(1,1/2) Supersymmetric U(1) Gauge Theory
Takeo Araki, Katsushi Ito, Akihisa Ohtsuka
We study a reduction of deformation parameters in non(anti)commutative N=2 harmonic superspace to those in non(anti)commutative N=1 superspace. By this reduction we obtain the exac…
N=2 Supersymmetric U(1) Gauge Theory in Noncommutative Harmonic Superspace
Takeo Araki, Katsushi Ito, Akihisa Ohtsuka
We study N=2 supersymmetric U(1) gauge theory in the noncommutative harmonic superspace with nonanticommutative fermionic coordinates. We examine the gauge transformation which pre…
