sasso

The old beam was created by smashing long bunches of protons into a target to produce neutrinos, which would then travel on to Gran Sasso.

The prediction had been posted weeks earlier by a seismologist at the Gran Sasso National Laboratory in Abruzzi, Italy.

With the beam tightened up, the neutrinos still arrived at Gran Sasso 60 nanoseconds faster than light would have.

The different gravitational strengths at the two labs therefore mean that clocks at CERN run slightly slower than clocks at Gran Sasso.

The neutrinos may be taking a shortcut through space-time, by travelling from Cern to Gran Sasso through extra dimensions.

By the time it gets to Gran Sasso the beam has fanned out, and big though it is, Opera only sees neutrinos from part of the beam.

The OPERA team responded that they had correctly used the GPS to synchronize their clocks at CERN and Gran Sasso.

They also measure the time distribution of neutrinos arriving at Gran Sasso.

The finding was made by researchers at Cern in Switzerland and Gran Sasso in Italy.

There is much checking, re-checking and repetition to do before the Gran Sasso anomaly is proved or disproved.

They carried out an experiment that fired a beam of neutrinos from CERN to Italy's INFN Gran Sasso Laboratory.

That afternoon, 12 German gliders crashed-landed on the Gran Sasso's slopes.

Here's the basic idea: OPERA has a detector in Gran Sasso Italy, about 730 km from the LHC.

The result, published in arXiv, an online database, is based on data from 15, 000 neutrinos detected at Gran Sasso over three years.

A number of underground experiments, such as XENON100 at Italy's Gran Sasso National Laboratory near L'Aquila, and the Cryogenic
