OPERA-reassessing data on the energy dependence of the speed of neutrinos
Giovanni Amelino-Camelia, Giulia Gubitosi, Niccoló Loret +3
We offer a preliminary exploration of the two sides of the challenge provided by the recent OPERA data on superluminal neutrinos. On one side we stress that some aspects of this re…
Using CMB data to constrain non-isotropic Planck-scale modifications to Electrodynamics
Giulia Gubitosi, Marina Migliaccio, Luca Pagano +4
We develop a method to constrain non-isotropic features of Cosmic Microwave Background (CMB) polarization, of a type expected to arise in some models describing quantum gravity eff…
Purely Kinetic Coupled Gravity
Giulia Gubitosi, Eric V. Linder
Cosmic acceleration can be achieved not only with a sufficiently flat scalar field potential but through kinetic terms coupled to gravity. These derivative couplings impose a shift…
Relative Locality in -Poincaré
Giulia Gubitosi, Flavio Mercati
We show that the -Poincaré Hopf algebra can be interpreted in the framework of curved momentum space leading to the relativity of locality \cite{AFKS}. We study the geometric pr…
