A new perspective on non-commutative deformations of field and gauge theories
Riccardo Borsato, Tim Meier
We construct non-commutative deformations of field and gauge theories based on star-products implemented by Drinfel'd twists. We are able to encompass a large family of twists, inc…
Integrable spin chains in twisted maximally supersymmetric Yang-Mills theory
Tim Meier, Stijn J. van Tongeren
We study an angular dipole deformation of maximally supersymmetric Yang-Mills theory (SYM) that preserves its classical scale invariance. We show that two-point functions of suitab…
Twisting Twistor space
Tim Meier, Eggon Viana
We construct twisted noncommutative gauge theories on twistor space and show that they are equivalent to four-dimensional twist-noncommutative gauge theories. In particular, we stu…
Non-commutative deformations of gauge theories via Drinfel'd twists of the scale symmetry
Riccardo Borsato, Tim Meier
In this paper we consider gauge theories that are relativistic and scale-invariant, and we construct their deformed versions via suitable star products. In particular, the non-comm…
