In these lectures I will discuss the following topics: (1) Twistors in 4 flat dimensions: Massless particles; constrained phase space (x,p) versus twistors; Physical states in twistor space. (2) Introduction to 2T-physics and derivation of 1T-physics holographs and twistors: Emergent spacetimes & dynamics, holography, duality; Sp(2,R) gauge symmetry, constraints, solutions and (d,2); Global symmetry, quantization and the SO(d,2) singleton. (3) Twistors for particle dynamics in d dimensions… 
Twistor transform in d dimensions and a unifying role for twistors
Twistors in four dimensions d=4 have provided a convenient description of massless particles with any spin, and this led to remarkable computational techniques in Yang-Mills field theory. Recently it
Generalized twistor transform and dualities with a new description of particles with spin beyond free and massless
A generalized twistor transform for spinning particles in 3+1 dimensions is constructed that beautifully unifies many types of spinning systems by mapping them to the same twistor Z{sub A}=({mu}{sup
Interacting two-time physics field theory with a BRST gauge invariant action
We construct a field theoretic version of 2T physics including interactions in an action formalism. The approach is a Becchi-Rouet-Stora-Tyutin (BRST) formulation based on the underlying Sp(2,R)
(Pre-)Hilbert spaces in twistor quantization
In twistor theory, the canonical quantization procedure, called twistor quantization, is performed with the twistor operators represented as ZA=ZA(∈C) and ZA=−∂/∂ZA. However, it has not been
Canonical formalism and quantization of a massless spinning bosonic particle in four dimensions
A twistor model of a free massless spinning particle in four-dimensional Minkowski space is studied in terms of space–time and spinor variables. This model is specified by a simple action, referred
Generalized dualities in one-time physics as holographic predictions from two-time physics
In the conventional formalism of physics, with 1-time, systems with different Hamiltonians or Lagrangians have different physical interpretations and are considered to be independent systems
Superspace formulations of the (super)twistor string
The superspace formulation of the worldvolume action of twistor string models is considered. It is shown that for the Berkovits-Siegel closed twistor string such a formulation is provided by a N = 4
Dualities among one-time field theories with spin, emerging from a unifying two-time field theory
The relation between two-time physics (2T-physics) and the ordinary one-time formulation of physics (1T-physics) is similar to the relation between a 3-dimensional object moving in a room and its
Dual field theories in (d-1)+1 emergent spacetimes from A unifying field theory in d+2 spacetime
According to two-time physics, there is more to space and time than can be garnered with the ordinary formulation of physics. Two-time physics has shown that the standard model of particles and

Twistor superstring in two-time physics
By utilizing the gauge symmetries of two-time physics (2T physics), a superstring with linearly realized global SU(2,2|4) supersymmetry in 4+2 dimensions (plus internal degrees of freedom) is
AdS Twistors for Higher Spin Theory
We construct spectra of supersymmetric higher spin theories in D = 4, 5 and 7 from twistors describing massless (super-)particles on AdS spaces. A massless twistor transform is derived in a geometric
Two time physics with gravitational and gauge field backgrounds
It is shown that all possible gravitational, gauge and other interactions experienced by particles in ordinary d dimensions (one time) can be described in the language of two-time physics in a
Perturbative Gauge Theory as a String Theory in Twistor Space
Perturbative scattering amplitudes in Yang-Mills theory have many unexpected properties, such as holomorphy of the maximally helicity violating amplitudes. To interpret these results, we Fourier
Cubic twistorial string field theory
Witten has recently proposed a string theory in twistor space whose D-instanton contributions are conjectured to compute = 4 super-Yang-Mills scattering amplitudes. An alternative string theory in
Conformal Supergravity in Twistor-String Theory
Conformal supergravity arises in presently known formulations of twistor-string theory either via closed strings or via gauge-singlet open strings. We explore this sector of twistor-string theory,
Single twistor description of massless, massive, AdS, and other interacting particles
The Penrose transform between twistors and the phase space of massless particles is generalized from the massless case to an assortment of other particle dynamical systems, including special examples
