A possible statistical mechanism of anomalous neutrino velocity in OPERA experiment?

Understand

The set of kinetic equations describing the process of conversion of a beam of protons into mesons and then to neutrinos is solved.

• The asymptotic evolution of the density profile of neutrinos is essentially the same as that obtained in the previous version of the note for a simple model of uniformly damped wave-packet.
• It shows again that the recently reported "superluminal neutrinos" could be considered as a purely statistical effect due to the fact that the detected neutrinos represent a biased sample of initial protons.
