Primordial spectra from modified Bekenstein-Hawking entropy law

Marco de Cesare, Giulia Gubitosi, Varun Kushwaha

Many approaches to quantum gravity predict logarithmic corrections to the Bekenstein-Hawking entropy. Within the spacetime-thermodynamic description of gravity, such corrections le…

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…

Constraints on quantum spacetime-induced decoherence from neutrino oscillations

Vittorio D'Esposito, Giulia Gubitosi

We investigate the implications of decoherence induced by quantum spacetime properties on neutrino oscillation phenomena. We develop a general formalism where the evolution of neut…
