Testing the special relativity theory with neutrino interactions

A recent measurement of the neutrino velocity by the OPERA experiment and the prediction of energy loss of superluminal neutrinos via the pair creation process ?????e+e? stimulated a search of isolated e+e? pairs in detectors with good tracking capability traversed by a large flux of high-energy neutrinos like NOMAD. NOMAD has already searched for similar topologies. These results can be reinterpreted to provide stringent limits on special-relativity-violating parameters separately for each ? species.
