DATE: December 16 (Mon.) 14:00 − 15:00
PLACE: 4th Building 2F, Lecture Room 2


I will briefly discuss the recent measurement of the speed of neutrinos by the OPERA collaboration, which reported an apparent faster than light propagation. The discussion will focus on some theoretical aspects of the super-luminal interpretation: energy dependence, Cherenkov emission, spectrum of the pion decay. Finally, I will present preliminary results based on a model in 5 dimensions.
