“…The ν µ → ν e andν µ →ν e appearance data of the LSND [35], KARMEN [36], NOMAD [37], MiniBooNE [38] and ICARUS [39] experiments. In particular, we use only the MiniBooNE data above 475 MeV, because the data at lower energy contains an , number of degrees of freedom (NDF), goodness-of-fit (GoF) and best-fit values of the mixing parameters obtained in our 3+0, 3+1 and 3+2 fits of short-baseline oscillation data.…”

Sterile neutrinos: Cosmology versus short-baseline experiments

Cosmology and short baseline neutrino oscillation data both hint at the existence of light sterile neutrinos with masses in the 1 eV range. Here we perform a detailed analysis of the sterile neutrino scenario using both cosmological and SBL data. We have additionally considered the possibility that the extra neutrino degrees of freedom are not fully thermalised in the early universe. Even when analyzing only cosmological data we find a preference for the existence of massive sterile neutrinos in both (3+1) and (3+2) scenarios, and with the inclusion of SBL data the evidence is formally at the 3.3σ level in the case of a (3+1) model. Interestingly, cosmological and SBL data both point to the same mass scale of approximately 1 eV. In the (3+1) framework WMAP9+SPT provide a value of the sterile mass eigenstate m4 = (1.72 ± 0.65) eV: this result is strenghtened by adding the prior from SBL posterior to m4 = (1.27 ± 0.12) eV (m4 = (1.23 ± 0.13) eV when SDSS is also considered in the cosmological analysis). In the (3+2) scheme, two additional, non-fully thermalized, neutrinos are compatible with the whole set of cosmological and SBL data, leading to mass values of m4 = (0.95 ± 0.30) eV and m5 = (1.59 ± 0.49) eV. The inclusion of Planck data does not change our considerations about the mass scale; concerning the extra neutrino degrees of freedom, invoking a partial thermalisation the 3+1 model is still consistent with the latest data.

“…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]. We report here a new precision measurement of the speed of neutrinos using the NuMI muon neutrino beam at the Fermi National Accelerator Laboratory (Fermilab) [13] and the two MINOS detectors [14], using a significantly upgraded time synchronization system and an exposure of 0.8×10 20 protons on target in March and April of 2012.…”

“…In particular, the OPERA result did not seem to fit with the patterns just described, as a strong LSV effect was manifesting itself at an energy scale too far below the UHE scales. Now the claim of a possible superluminal neutrino has been withdrawn [43] after having been disavowed by a more recent experiment [44].…”

Abstract. With the present understanding of data, the observed flux suppression for ultra-high energy cosmic rays (UHECR) at energies above 4.10 19 eV can be a signature of the Greisen-Zatsepin-Kuzmin (GZK) cutoff or be related to a similar mechanism. But it may also correspond, for instance, to the maximum energies available at the relevant sources. In both cases, violations of special relativity modifying cosmic-ray propagation or acceleration at very high energy can potentially play a role. Other violations of fundamental principles of standard particle physics (quantum mechanics, energy and momentum conservation, vacuum homogeneity and "static" properties, effective space dimensions, quark confinement...) can also be relevant at these energies. In particular, UHECR data would in principle allow to set bounds on Lorentz symmetry violation (LSV) in patterns incorporating a privileged local reference frame (the "vacuum rest frame", VRF). But the precise analysis is far from trivial, and other effects can also be present. The effective parameters can be related to Planckscale physics, or even to physics beyond Planck scale, as well as to the dynamics and effective symmetries of LSV for nucleons, quarks, leptons and the photon. LSV can also be at the origin of GZK-like effects. In the presence of a VRF, and contrary to a "grand unification" view, LSV and other violations of standard principles can modify the internal structure of particles at very high energy and conventional symmetries may cease to be valid at energies close to the Planck scale. We present an updated discussion of these topics, including experimental prospects, new potentialities for high-energy cosmic ray phenomenology and the possible link with unconventional pre-Big Bang scenarios, superbradyon (superluminal preon) patterns... The subject of a possible superluminal propagation of neutrinos at accelerator energies is also dealt with.
