Contribution

It presents a novel twistor phase space approach to model and quantize interacting massless particles with internal structure.

Findings

Successful canonical quantization of the twistor phase space dynamics.

A general description of the dynamics of finite interacting massless particles.

Poincare invariance maintained in the quantization process.

Abstract

Twistor phase spaces are used to provide a general description of the dynamics of a finite number of directly interacting massless spinning particles forming a closed relativistic massive and spinning system with an internal structure. A Poincare invariant canonical quantization of the so obtained twistor phase space dynamics is performed.
