The Opera experiment made headlines around the world last September with
their announcement that neutrinos sent from the CERN laboratories to Gran Sasso appeared to be moving at superluminal speed. After repeated claims of retests that gave the same results, it is now accepted that it was an instrumentation error that caused the anomaly.
In the aftermath, Antonio Ereditato (left), spokesperson of the Opera collaboration,
announced on March 30 that he stepped down. He is no longer leading the Opera
experiment.
This happened after a workshop was held at the Gran Sasso laboratories, where
the various experiments reported their findings and discussed them (no details released yet). Following the workshop, the
Opera collaboration is reported to have voted on removing Ereditato from
the leadership position. The motion did not pass, but the voting showed
that the collaboration was split, and this may eventually have led
Ereditato to step down.
Question is, was it wrong from him to push the announcement of the headline-grabbing results too early? Or is it perhaps good that he pushed the slow-grinding wheels of science a little? Tommaso Dorigo thinks the latter:
"Let us instead try to educate the public on the fact that what happened
to Opera's superluminal neutrino claim is good science: we study an
effect, find something unexpected, and then try to kill the effect with
all our means by studying it in more detail and with all the other tools
we have available. What survives this kind of treatment is usually only
real, trustable effects."
