Description
We discuss effects suggested to be induced in the neutrino physics by
models of quantum gravity. In particular, quantum decoherence can lead to fewer
neutrinos of all active flavours being detected in a long baseline experiments
as compared to three-flavour standard neutrino oscillations. We discuss the
potential of CNGS and J-PARC beams in constraining models of quantum gravity
induced decoherence. Another effect is related to the interaction of energetic
particles with quantum gravity induced foamy structure of space-time. This
interaction might violate Lorentz invariance, so that a radiation probe
does not propagate at a universal speed. We consider the limits that may be set
on such violation of Lorentz invariance using data from supernova explosions and
the CNGS long-baseline experiment.
