The photon-neutrino interaction in non-commutative gauge field theory and astrophysical bounds
Peter Schupp, Josip Trampetic, Julius Wess +1
In this letter we propose a possible mechanism of left- and right-handed neutrino couplings to photons, which arises quite naturally in non-commutative gauge field theory. We estim…

Noncommutative gerbes and deformation quantization
Paolo Aschieri, Igor Bakovic, Branislav Jurco +1
We define noncommutative gerbes using the language of star products. Quantized twisted Poisson structures are discussed as an explicit realization in the sense of deformation quant…
Non-Commutative GUTs, Standard Model and C,P,T
Paolo Aschieri, Branislav Jurco, Peter Schupp +1
Noncommutative Yang-Mills theories are sensitive to the choice of the representation that enters in the gauge kinetic term. We constrain this ambiguity by considering grand unified…
