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 …
Complete ADHM Sigma Model
Abbas Ali, P. P. Abdul Salih
The field theoretic ADHM instantons have stringy generalizations as linear sigma models. These were constructed by Witten in 1995. Recently Ali and Ilahi constructed a complementar…
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…
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…
