κ-deformed spin-1/2 field
Tadeusz Adach, Andrea Bevilacqua, Jerzy Kowalski-Glikman +2
In this paper, we investigate the Poincaré and discrete symmetries of a -deformed spin- field, extending recent results obtained for scalar fields. We construct an act…

Asymmetry in momentum space: restoring invariance of -field theory
Tadeusz Adach, Andrea Bevilacqua, Jerzy Kowalski-Glikman +1
The positive and negative energy modes of a field theory in -Minkowski/-Poincaré noncommutative spacetime have very different symmetry properties. This can be understood geom…

Complex scalar field in κ-Minkowski noncommutative spacetime
Tadeusz Adach
We present a comparison between translation charges for several Lagrangians for the -deformed complex scalar field using the canonical method. The Lagrangians are shown to be re…
