CERN OPERA’s FTL neutrinos are rejected by CERN ICARUS scientists

November 21, 2011

OPERA is one set of experiments at CERN’s Italian partner labs at Gran Sasso and ICARUS is another.

In September Opera reported the FTL neutrinos to widespread scepticism, wonder and some delight. Last Friday the OPERA scientists reported that new experiments supported the September results.

But on Saturday the ICARUS scientists reported – also on the same website-  that they had analysed the September results and that they do not stand up!!!

Reuters reports:

An international team of scientists in Italy studying the same neutrino particles colleagues say appear to have travelled faster than light rejected the startling finding this weekend, saying their tests had shown it must be wrong.

New tests support previous result of faster than light neutrinos

November 18, 2011

The CERN results in September indicating faster than light neutrinos have stood up to one set of tests to check the result.

Reuters:

The new experiment at the Gran Sasso laboratory, using a neutrino beam from CERN in Switzerland, 720 km (450 miles) away, was held to check findings in September by a team of scientists which were greeted with some skepticism. Scientists at the Italian Institute for Nuclear Physics (INFN) said in a statement on Friday that their new tests aimed to exclude one potential systematic effect that may have affected the original measurement. ….
