Found their paper in arXive.
The ICARUS team states in their Abstract that:
"For this value of δ a very significant deformation of the neutrino
energy spectrum and an abundant production of photons and e+e-‐ pairs
should be observed at LNGS."
And in their paper they also say:
"As well known, a charged particle travelling at a speed exceeding the
one of light is necessarily emitting coherent radiation (Cherenkov
radiation) in a characteristic light cone."
And here appears to be the fault in their logic. A particle born at a
speed lower than c in a vacuum would be emitting Cherenkov radiation
when it entered an area with a lower value of c because its transfer of
energy would cause it to slow down.
This may not be true of a particle born above c in a vacuum. This may
be true because, looking at the mathematical curve for mass/length/time
on the side for a particle born above c we see that as the particle
sheds energy it goes faster, not slower. This increase in speed has not
been studied and as such we don't know its effects yet.

The data ICARUS supplies may point to this anomaly because:
Figure 2 - Does show that the muon momentum distribution is consistent
with the neutrinos going slower than c.
Figure 3 -They used data before it was completely corrected, so its
usefulness is very suspect. And even then this data shows a slight
reduction from the expected results, but within range of the expected
results.
Figure 4 - The Monty Carlo distribution result is out range from the
data results. The two peaks do not line up either. This would be just
an anomaly in the data except the curve fit to the data points shows a
consistent shift in the data to a lower value than we would expect.
Figure 5 - If Cherenkov radiation is not emitted when a particle born >
c speeds up, or if the radiation emitted is out of the detector expected
energy ranges then this graph becomes inapplicable. This may be the
case, since Cherenkov radiation is emitted in the region of the graph
where a particle goes from above the c for that material to below the c
for that material. In this case, no Cherenkov radiation may be present
and no pair production may occur.
Putting 3, 4 and 5 together would say that there is something in the
data that does not quite fit.
Overall, the ICARUS data is suspect enough both in values and concept to
the extent that it can not refute the FTL times by OPERA.
