We give a brief review of the twistor string approach to supersymmetric Yang‐Mills theories with an emphasis on the different formulations of (super)string models in supertwistor space and their superspace form. We discuss the classical equivalence among the Siegel closed twistor string and the Lorentz harmonics formulation of the (N = 4) tensionless superstring, and notice the possible relation of the twistor string to the D = 10 Green‐Schwarz superstring action, as well as to models in the… 

Spinor Moving Frame, Polarized Scattering Equation for 11D Supergravity, and Ambitwistor Superstring

We reveal and discuss the spinor moving frame origin of the formalism of the 11D polarized scattering equation by Geyer and Mason [21]. In particular, we use the spinor moving frame formulation of

Untwisting the twistor superstring

The twistor superstring, which describes N=4 super Yang-Mills trees, is taken off-shell (for loops) by generalizing Penrose twistors (which describe on-shell momenta) to

An Alternative String Theory in Twistor Space for N=4 Super-yang-mills

In this letter, an alternative string theory in twistor space is proposed for describing perturbative N=4 super-Yang-Mills theory. Like the recent proposal of Witten, this string theory uses twistor

N=1 super- p-branes in twistor-like Lorentz harmonic formulation

A unique twistor-like Lorentz harmonic formulation for all N=1 supersymmetric extended objects (super-p-branes) moving in spacetime of arbitrary dimension D (admissible for given p) is suggested. The

On the covariant quantization of tensionless bosonic strings in AdS spacetime

The covariant quantization of the tensionless free bosonic (open and closed) strings in AdS spaces is obtained. This is done by representing the AdS space as an hyperboloid in a flat auxiliary space

SUPERPARTICLES, TWISTORS AND SIEGEL SYMMETRY

It is shown that an explicit incorporation of twistor variables into the lagrangian of a massless relativistic particle together with the local supersymmetrization of its proper time leads to a
