Minimal Length Scale in Annihilation

Irina Dymnikova, Alexander Sakharov, Jurgen Ulbricht

Experimental data suggest the existence of a minimal length scale in annihilation process for the reaction e+e- --> gamma gamma (gamma). Nonlinear electrodynamics coupled to gravit…

Exploration of Possible Quantum Gravity Effects with Neutrinos II: Lorentz Violation in Neutrino Propagation

Alexander Sakharov, John Ellis, Nicholas Harries +2

It has been suggested that the interactions of energetic particles with the foamy structure of space-time thought to be generated by quantum-gravitational (QG) effects might violat…

Exploration of Possible Quantum Gravity Effects with Neutrinos I: Decoherence in Neutrino Oscillations Experiments

Alexander Sakharov, Nick Mavromatos, Anselmo Meregaglia +2

Quantum gravity may involve models with stochastic fluctuations of the associated metric field, around some fixed background value. Such stochastic models of gravity may induce dec…

Polarization mesurements of gamma ray bursts and axion like particles

Andre Rubbia, Alexander Sakharov

A polarized gamma ray emission spread over a sufficiently wide energy band from a strongly magnetized astrophysical object like gamma ray bursts (GRBs) offers an opportunity to tes…

Quantum-Gravity Decoherence Effects in Neutrino Oscillations: Expected Constraints from CNGS and J-PARC

Nick E. Mavromatos, Anselmo Meregaglia, Andre Rubbia +2

Quantum decoherence, the evolution of pure states into mixed states, may be a feature of quantum-gravity models. In most cases, such models lead to fewer neutrinos of all active fl…
