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…
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…
Particle production in a light-cone gauge fixed Jordanian deformation of
Riccardo Borsato, Sibylle Driezen
We consider a string on a Jordanian deformation of the spacetime. This model belongs to the larger class of Homogeneous Yang-Baxter deformations, which preserve c…
Integrability of the -deformation of the PCM with spectators
Riccardo Borsato, Georgios Itsios, J. Luis Miramontes +1
We construct a generalisation of the -deformation of the Principal Chiral Model (PCM) where we deform just a subgroup of the full symmetry group . We find that demanding…
