Quantum-spacetime phenomenology

G Amelino-Camelia - Living Reviews in Relativity, 2013 - Springer
I review the current status of phenomenological programs inspired by quantum-spacetime
research. I stress in particular the significance of results establishing that certain data …

Matter matters in asymptotically safe quantum gravity

P Donà, A Eichhorn, R Percacci - Physical Review D, 2014 - APS
We investigate the compatibility of minimally coupled scalar, fermion and gauge fields with
asymptotically safe quantum gravity, using nonperturbative functional renormalization group …

In vacuo dispersion features for gamma-ray-burst neutrinos and photons

G Amelino-Camelia, G D'Amico, G Rosati, N Loret - Nature Astronomy, 2017 - nature.com
Over the past 15 years there has been considerable interest in the possibility of quantum-
gravity-induced in vacuo dispersion, the possibility that spacetime itself might behave …

Searches for baryon number violation in neutrino experiments: a white paper

PSB Dev, LW Koerner, S Saad, S Antusch… - Journal of Physics G …, 2024 - iopscience.iop.org
Baryon number conservation is not guaranteed by any fundamental symmetry within the
standard model, and therefore has been a subject of experimental and theoretical scrutiny …

[HTML][HTML] Gravitational corrections to Yukawa systems

O Zanusso, L Zambelli, GP Vacca, R Percacci - Physics Letters B, 2010 - Elsevier
We compute the gravitational corrections to the running of couplings in a scalar-fermion
system, using the Wilsonian approach. Our discussion is relevant for symmetric as well as …

Functional renormalization with fermions and tetrads

P Dona, R Percacci - Physical Review D—Particles, Fields, Gravitation, and …, 2013 - APS
We investigate some aspects of the renormalization group flow of gravity in the presence of
fermions, which have remained somewhat puzzling so far. The first is the sign of the …

[HTML][HTML] IceCube and GRB neutrinos propagating in quantum spacetime

G Amelino-Camelia, L Barcaroli, G D'Amico, N Loret… - Physics Letters B, 2016 - Elsevier
Two recent publications have reported intriguing analyses, tentatively suggesting that some
aspects of IceCube data might be manifestations of quantum-gravity-modified laws of …

Consistency of matter models with asymptotically safe quantum gravity

P Donà, A Eichhorn, R Percacci - Canadian Journal of Physics, 2015 - cdnsciencepub.com
We discuss the compatibility of quantum gravity with dynamical matter degrees of freedom.
Specifically, we present bounds we obtained in Donà et al.(Phys. Rev. D, 89, 084035 (2014) …

Kinetic mixing, proton decay and gravitational waves in SO (10)

R Maji, Q Shafi - Journal of High Energy Physics, 2024 - Springer
A bstract We present an SO (10) model in which a dimension five operator induces kinetic
mixing at the GUT scale between the abelian subgroups U (1) B− L and U (1) R. We discuss …

Light color octet scalars in the minimal grand unification

S Bertolini, L Di Luzio, M Malinský - Physical Review D—Particles, Fields …, 2013 - APS
We analyze the relation between the present (and foreseen) bounds on matter stability and
the presence of TeV-scale color octet scalar states in nonsupersymmetric SO (10) grand …
