Symmetry of Superstrings
Abbas Ali, Mohsin Ilahi
We discuss the importance of symmetry of large superconformal algebra for finding its free field realization that is more complete than the most commonly used one, that…
Superalgebra Doubling in Superstrings
Abbas Ali
We propose a solution to the mystery of superalgebra doubling found by Giveon-Kutasov-Seiberg in their construction of worldsheet approach to spacetime superconformal symmetry for…
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…
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…
Complementary ADHM Instanton Sigma Model
Abbas Ali, Mohsin Ilahi
We construct the ADHM linear sigma model that is complementary to a model constructed by Edward Witten in 1995. Analysis of the corresponding moduli space leads to the resolution o…
Conformal symmetry of superstrings on and D1/D5 system
Abbas Ali
Conformal field theory of the D1/D5 system and superstrings on is studied with particular attention to the world-sheet fields corresponding to the …
