Twistors and 2T-physics

TL;DR

This paper discusses how 2T-physics offers a higher-dimensional framework that unifies and extends twistor theory, enabling new formulations of superstrings in various dimensions relevant to string theory and supersymmetric models.

Contribution

It introduces a 2T-physics based approach to formulating twistors and superstrings in higher dimensions, revealing new dualities and formulations in string theory.

Findings

Formulated a d=10 twistor superstring for AdS5xS5 backgrounds.

Developed a d=6 twistor superstring related to superconformal theories.

Provided a natural generalization of twistors to higher dimensions via 2T-physics.

Abstract

Two-Time physics applies broadly to the formulation of physics and correctly describes the physical world as we know it. Recently it was applied to a 2T re-formulation of the d=4 twistor superstring, which was suggested by Witten as an efficient approach for computations of physical processes in the maximally supersymmetric N=4 Yang-Mills field theory in four dimensions. The 2T formalism provides a six dimensional view of this theory and suggests the existence of other d=4 dual forms of the same theory. Furthermore the 2T approach led to the first formulation of a twistor superstring in d=10 appropriate for AdS{5}xS{5} backgrounds, and a twistor superstring in d=6 related to the little understood superconformal theory in d=6. The proper generalization of twistors to higher dimensions is an essential ingredient which is provided naturally by 2T-physics. These developments are summarized in this lecture.
