A semi-infinite matrix analysis of the BFKL equation
N. Bethencourt de León, G. Chachamis, A. Romagnoni +1
The forward BFKL equation is discretised in virtuality space and it is shown that the diffusion into infrared and ultraviolet momenta can be understood in terms of a semi-infinite…
Nonanticommutative U(1) SYM theories: Renormalization, fixed points and infrared stability
Marco S. Bianchi, Silvia Penati, Alberto Romagnoni +1
Renormalizable nonanticommutative SYM theories with chiral matter in the adjoint representation of the gauge group have been recently constructed in [arXiv:0901.3094]. In the prese…
A renormalizable N=1/2 SYM theory with interacting matter
Silvia Penati, Alberto Romagnoni, Massimo Siani
We consider nonanticommutative SYM theories with chiral matter in the adjoint representation of the SU(N) x U(1) gauge group. In a superspace setup and manifest background covarian…
Non(anti)commutative SYM theory: Renormalization in superspace
Marcus T. Grisaru, Silvia Penati, Alberto Romagnoni
We present a systematic investigation of one-loop renormalizability for nonanticommutative N=1/2, U(N) SYM theory in superspace. We first discuss classical gauge invariance of the…
Nonanticommutative superspace and N= 1/2 WZ model
M. T. Grisaru, S. Penati, A. Romagnoni
In these proceedings we review the main results concerning superspace geometries with nonanticommutative spinorial variables and field theories formulated on them. In particular, w…
Two-loop Renormalization for Nonanticommutative N=1/2 Supersymmetric WZ Model
Marcus T. Grisaru, Silvia Penati, Alberto Romagnoni
We study systematically, through two loops, the divergence structure of the supersymmetric WZ model defined on the N=1/2 nonanticommutative superspace. By introducing a spurion fie…
