Palatial twistor theory and the twistor googly problem
1Mathematical Institute, Andrew Wiles Building, Woodstock Road, Oxford OX2 6GG, UK penroad@nexus.ox.ac.uk.
Palatial twistor theory resolves the 40-year-old "googly problem" in twistor theory. It provides a twistor description for right-handed massless fields, extending conventional twistor theory with non-commutative algebra.
Area of Science:
- Theoretical Physics
- Mathematical Physics
- String Theory
Background:
- The twistor program aims to describe fundamental physics using twistor geometry.
- A significant challenge, the 'googly problem', has hindered the description of right-handed massless fields (positive helicity) within this framework for nearly 40 years.
- Existing twistor constructions, like the nonlinear graviton and Ward constructions, successfully describe left-handed fields (negative helicity) but not right-handed ones.
Purpose of the Study:
- To propose a novel theoretical framework, palatial twistor theory, to resolve the 'googly problem'.
- To provide a twistor description for right-handed interacting massless fields.
- To extend conventional twistor theory to accommodate positive helicity fields.
Main Methods:
- Introduction of palatial twistor theory, a new approach within the twistor program.
- Incorporation of a non-commutative holomorphic quantized twistor 'Heisenberg algebra'.
- Extension of conventional twistor theory's holomorphic functions to include operators of twistor differentiation.
Main Results:
- An explicit proposal for palatial twistor theory is presented.
- The theory is illustrated with a specific application to gravitation.
- The proposed framework successfully addresses the long-standing 'googly problem'.
Conclusions:
- Palatial twistor theory offers a viable solution to the 'googly problem' in twistor theory.
- This new theory enables a twistor description for right-handed massless fields.
- The incorporation of non-commutative algebraic structures and twistor differentiation operators represents a significant advancement in twistor theory.
