Relativity accommodates superluminal mean velocities    [PDF]

B. Alles

Contrary to a widespread belief, measures of velocity can yield a value
larger than $c$, the instantaneous light speed in vacuum, without contradicting
Einstein's relativity. Nevertheless, the effect turns out to be too small to
explain the recently claimed superluminal velocity by the OPERA collaboration.
Several other general relativistic effects acting on the OPERA neutrinos are
also analyzed. All of them are unable to explain the OPERA result.
