“…Superluminal Neutrino Velocity Constraint Assuming δ e ≥ 0 Since eq. (6) implies that δ νe ≫ δ e , we find that δ ν ≃ δ νe ∼ 5.6 × 10 −19 , almost ten orders of magnitude better than the time-of-flight constraint from the SN1987A neutrino burst [20] and more than five orders of magnitude better than the constraint obtained from the study of atmospheric neutrino spectra [21]. Our new constraints apply directly to the dimension-4 operators in the SME; c e T T ≡ −δ e andc (4) ≡ −δ ν (see tables D6 and D19 of Ref.…”

“…In ad-dition, time-of-flight constraints from the detection of a multi-MeV neutrino burst from supernova 1987A [18,19] yielded the constraint δ ν ≤ 2×10 −9 [20]. A comparison of atmospheric neutrino spectra with theoretical spectra expected from the change in the pion decay rate if neutrinos are superluminal has yielded the indirect constraint δ ν ≤ O(10 −13 ) [21].…”

The observation of two PeV-scale neutrino events reported by Ice Cube allows one to place constraints on Lorentz invariance violation (LIV) in the neutrino sector. After first arguing that at least one of the PeV IceCube events was of extragalactic origin, I derive an upper limit for the difference between putative superluminal neutrino and electron velocities of ≤∼ 5.6 × 10 −19 in units where c = 1, confirming that the observed PeV neutrinos could have reached Earth from extragalactic sources. I further derive a new constraint on the superluminal electron velocity, obtained from the observation of synchrotron radiation from the Crab Nebula flare of September, 2010. The inference that the > 1 GeV γ-rays from synchrotron emission in the flare were produced by electrons of energy up to ∼ 5.1 PeV indicates the nonoccurrence of vacuumĆerenkov radiation by these electrons. This implies a new, strong constraint on superluminal electron velocities δ e ≤∼ 5×10 −21 . It immediately follows that one then obtains an upper limit on the superluminal neutrino velocity alone of δ ν ≤∼ 5.6 × 10 −19 , many orders of magnitude better than the time-of-flight constraint from the SN1987A neutrino burst. However, if the electrons are subluminal the constraint on |δ e | ≤∼ 8 × 10 −17 , obtained from the Crab Nebula γ-ray spectrum, places a weaker constraint on superluminal neutrino velocity of δ ν ≤∼ 8 × 10 −17 .

“…From reference [13], we find sin 2 2θ v < 0.35 for δv > 10 −35 . Furthermore, the velocity of ν e (i.e., its dominant velocity eigenstate) cannot differ from the velocity of light by more than two parts in 10 9 [14].…”

“…Previous limits of Lorentz invariance include at a much lower energy (around 10 MeV), a stringent limit of v−c c < 2 × 10 −9 from the observation of (anti)neutrinos emitted by the SN1987A supernova, [51]. With a baseline analogous to that of OPERA, but at lower neutrino energies (E…”

We reconsider Lorentz Violation (LV) at the fundamental level. We argue that Lorentz Violation is intimately connected with gravity and that LV couplings in QFT must always be fields in a gravitational sector. Diffeomorphism covariance, implementing general charnges of frame, is intact and the LV couplings transform as tensors under coordinate/frame changes. Therefore searching for LV is one of the most sensitive ways of looking for new physics, either new interactions or modifications of known ones. Energy dissipation/Cerenkov radiation is shown to be a generic feature of LV in QFT. A general computation is done in strongly coupled theories with gravity duals. It is shown that in scale invariant regimes, the energy dissipation rate depends non-trivially on two characteristic exponents, the Lifshitz exponent and the hyperscaling violation exponent.
