TL;DR

This paper models the energy spectrum of superluminal neutrinos from OPERA and MINOS using a power law, highlighting the need for more precise data due to measurement uncertainties.

Contribution

It provides a novel approximation of the superluminal neutrino energy spectrum with a power law, constrained by experimental errors.

Findings

Energy spectrum approximated by a power law E=p+Cp^a

Parameters a and C are within specified ranges

Measurement errors limit the precision of the model

Abstract

We analyze the velocity dependence on energy of superluminal neutrino recorded by the OPERA and MINOS collaborations and manage to approximate the energy spectrum by a power law E=p+Cp^a where parameters must be taken in the range a=0.40--1.18 and C=1.5x10^{-5}--4.15x10^{-4} (momentum and energy are expressed in GeV). This rough estimation is constrained by the errors of measurements, and new experimental data are requested.
