article imageScientific team refutes faster than light neutrino experiment

After physicists in the OPERA experiment said they had obtained results which confirm previous test results that neutrinos travel faster than light, another team in the ICARUS experiment have said results from their study contradict the OPERA experiment.
Earlier Digital Journal reported that:
"...scientists[in the OPERA experiment] have repeated it...incorporation improvements in experiment design critics suggested. The new result from the latest tests is consistent with the first and suggests that neutrinos can travel faster than light. The new experiment design removes doubts arising from potential sources of error identified in the earlier experiment design."
CNews.com reports that scientists in the ICARUS experiment run by Italy's National Institute of National Physics, in a paper posted on Saturday on the same website, arxiv.org, that the result of the OPERA experiment was posted, have said their result “refute a superluminal (faster than light) interpretation of the OPERA result.”
According to the ICARUS team, evidence shows that neutrinos sent in pulses from CERN in Geneva would lose most of their energy if they traveled at the tiniest fraction faster than light. The scientists say that in their experiment, the neutrino pulse registered on their equipment an energy spectrum that corresponds with particles traveling at exactly the speed of light.
According to one of the scientists in the ICARUS experiment Tomasso Dorigo, the ICARUS finding was "very simple and definitive." Dorigo said:
“...the difference between the speed of neutrinos and the speed of light cannot be as large as that seen by OPERA, and is certainly smaller than that by three orders of magnitude, and compatible with zero.”
The ICARUS team says their result confirms Einstein's Special Relativity theory that nothing can travel faster than speed of light.
Physicists had greeted the OPERA experimental result "confirming" that neutrinos can travel faster than the speed of light with caution and skepticism. Digital Journal reports that Director of the National Institute of Nuclear and Particle Physics Jacques Martino, said:
"...physicists will continue to scrutinize the measurements for possible errors."
