Twistor Coverings and Feynman Diagrams
Faizan Bhat, Rajesh Gopakumar, Pronobesh Maity +1
Recently, a worldsheet dual to free Super Yang-Mills has been proposed in terms of twistor variables for , in parallel to that for the dual…
The String Dual to Free Super Yang-Mills
Matthias R. Gaberdiel, Rajesh Gopakumar
We propose a worldsheet description for the string theory dual to large , free super Yang-Mills in four dimensions. The worldsheet the…
The Worldsheet Dual of Free Super Yang-Mills in 4D
Matthias R. Gaberdiel, Rajesh Gopakumar
The worldsheet string theory dual to free 4d super Yang-Mills theory was recently proposed in arXiv:2104.08263. It is described by a free field sigma model on the twis…
Crossing Symmetric Dispersion Relations for Mellin Amplitudes
Rajesh Gopakumar, Aninda Sinha, Ahmadullah Zahed
We consider manifestly crossing symmetric dispersion relations for Mellin amplitudes of scalar four point correlators in conformal field theories (CFTs). This allows us to set up t…
