“…Observations of neutrinos from SN1987A [1][2][3] and accelerator experiments [4,5] have set limits on the difference between the speed of neutrino propagation and that of light, all consistent with v = c. In September 2011, the OPERA experiment reported a measurement [6], in striking conflict with both theory and experiment, which has since been revised to resolve the inconsistency [7]. The initial OPERA news motivated a number of further measurements [8][9][10][11][12].…”

“…In the past, a high-energy (E > 30 GeV) and short baseline experiment, [48,49], was able to test deviations down to v−c c < 4 × 10 −5 . The new (corrected) OPERA result is an order of magnitude better at v−c c < 10 −6 (announcements from the OPERA collaboration: [52,53]).…”

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.

“…We first recall that in the high-energy domain, where the effective neutrino mass is in the MeV range (see Refs. [4,5]) we assume that the neutrino mass is (almost) exclusively generated by the strong (nonperturbative) self-interaction with the X field. It is interesting to observe that polynomial behaviour of RG functions in the strong-coupling domain has recently been obtained by a sophisticated analysis of higher-order perturbative terms, for the β functions of φ 4 theories and of quantum electrodynamics [57,58].…”

If the mass of the X particle is negligible as compared to the mass of the neutrino in the high-energy domain, then the mass scaling must be independent of M X , and again, from dimensional analysis alone, we may conjecture that in the high-energy, strong-coupling limit,…”

Abstract:In this paper three things are done. (i) We investigate the analogues of Cerenkov radiation for the decay of a superluminal neutrino and calculate the Cerenkov angles for the emission of a photon through a W loop, and for a collinear electron-positron pair, assuming the tachyonic dispersion relation for the superluminal neutrino. The decay rate of a freely propagating neutrino is found to depend on the shape of the assumed dispersion relation, and is found to decrease with decreasing tachyonic mass of the neutrino.(ii) We discuss a few properties of the tachyonic Dirac equation (symmetries and plane-wave solutions), which may be relevant for the description of superluminal neutrinos seen by the OPERA experiment, and discuss the calculation of the tachyonic propagator. (iii) In the absence of a commonly accepted tachyonic field theory, and in view of an apparent "running" of the observed neutrino mass with the energy, we write down a model Lagrangian, which describes a Yukawa-type interaction of a neutrino coupling to a scalar background field via a scalar-minus-pseudoscalar interaction. This constitutes an extension of the standard model. If the interaction is strong, then it leads to a substantial renormalization-group "running" of the neutrino mass and could potentially explain the experimental observations. PACS
