Symmetry Structure of ADHM Sigma Models and Superstrings
Abbas Ali, Mohsin Ilahi, P. P. Abdul Salih +1
We clarify the supersymmetry structure of ADHM instanton linear sigma models, superconformal algebras and superconformal field theories dual to superstrings moving in …
Off-shell Formalism for Ali-Ilahi's ADHM Instanton Sigma Model
Abbas Ali, Mohsin Ilahi, P. P. Abdul Salih +1
In this brief note we present the off-shell superspace formalism for Ali-Ilahi's supersymmetric ADHM instanton linear sigma model in harmonic superspace. Ali-Ilahi's model…
Quantization of Complementary ADHM Sigma Model
Abbas Ali, Mohsin Ilahi, Shafeeq Rahman Thottoli
We discuss quantization of complementary ADHM sigma model in parallel with the quantization of the Witten's original ADHM sigma model by Lambert. The mechanisms of divergence cance…
Harmonic Superspace for Ali-Ilahi's ADHM Instanton Sigma Model
Abbas Ali, Mohsin Ilahi, P. P. Abdul Salih +1
ADHM Yang-Mills instantons are extended field theoretical objects. These are more general than the more familiar 't Hooft Yang-Mills instantons. Their counter parts exist in string…
