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…
CPT Violation: Theory and Phenomenology
Nick E. Mavromatos
Invariance under the combined transformations of CPT (in any order) is guaranteed in Quantum Field Theory in flat space times due to a basic theorem (CPT Theorem). The currently us…
Neutrinos and the Phenomenology of CPT Violation
N. E. Mavromatos
In this talk I review briefly theoretical models and ideas on quantum gravity approaches entailing CPT violation. Then, I discuss various phenomenological tests of CPT violation us…
A proposal on the possibility of detecting D-particles
Elias Gravanis, Nick E. Mavromatos
In a previous study we showed that D0-branes (particles) can operate as sources of very-high-energy radiation, as a result of an unstable spacetime distortion that follows a D0-par…
CPT and Superstring
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
We discuss the possibility that CPT violation may appear as a consequence of microscopic decoherence due to quantum-gravity effects, that we describe using a density-matrix formali…
