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 a…
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 g…
DSR-relativistic spacetime picture and the phenomenology of Planck-scale-modified time dilation
Giovanni Amelino-Camelia, Giulia Gubitosi, Pietro Pellecchia +2
The most active area of research in quantum-gravity phenomenology investigates the possibility of Planck-scale-modified dispersion relations, focusing mainly on two alternative sce…
On testing in-vacuo dispersion with the most energetic neutrinos: KM3-230213A case study
Giovanni Amelino-Camelia, Giacomo D'Amico, Giuseppe Fabiano +4
The phenomenology of in-vacuo dispersion, an effect such that quantum properties of spacetime slow down particles proportionally to their energies, has been a very active research…
Redshift leverage for the search of GRB neutrinos affected by quantum properties of spacetime
Giovanni Amelino-Camelia, Giacomo D'Amico, Vittorio D'Esposito +6
Some previous studies based on IceCube neutrinos had found intriguing preliminary evidence that some of them might be GRB neutrinos with travel times affected by quantum properties…
