How did you derive a negative bound? A negative bound suggests that arrival times could be slower than c.
The paper indicates that arrival times are always faster than c.
From the paper:
"An early arrival time of CNGS muon neutrinos with respect to the one computed assuming the speed of
light in vacuum of (60.7 ± 6.9 (stat.) ± 7.4 (sys.)) ns was measured."
