Possible Origin Of The Neutrino Speed Anomaly Reported By OPERA [PDF]

arXiv, 2011
Recently the OPERA collaboration reported a measurement of a superluminal speed of muon neutrinos travelling through the Earth's crust between their production site at CERN and their detection site under Gran Sasso, ~730 km away.

Cosmic neutrinos: dispersive and non-linear [PDF]

Phys. Rev. D 95, 063535 (2017), 2016
We present a description of cosmic neutrinos as a dispersive fluid. In this approach, the neutrino phase space is reduced to density and velocity fields alongside a scale-dependent sound speed. This sound speed depends on redshift, the initial neutrino phase space density and the cold dark matter gravitational potential.

Speed-up of neutrino transformations in a supernova environment [PDF]

Phys.Rev. D72 (2005) 045003, 2005
When the neutral current neutrino-neutrino interaction is treated completely, rather than as an interaction among angle-averaged distributions, or as a set of flavor-diagonal effective potentials, the result can be flavor mixing at a speed orders of magnitude faster than that one would anticipate from the measured neutrino oscillation parameters. It is

Precision measurement of the neutrino velocity with the ICARUS detector in the CNGS beam [PDF]

, 2012
During May 2012, the CERN-CNGS neutrino beam has been operated for two weeks for a total of 1.8 10^17 pot in bunched mode, with a 3 ns narrow width proton beam bunches, separated by 100 ns.

Measurement of sound speed versus depth in Antarctic ice with the South Pole Acoustic Test Setup [PDF]

Nucl.Instrum.Meth.Suppl.A604:175-178,2009, 2008
The feasibility and design of an acoustic neutrino detection array in the South Pole ice depend on the acoustic properties of the ice. The South Pole Acoustic Test Setup (SPATS) was built to evaluate the acoustic characteristics of the ice in the 1 to 100kHz frequency range.

Observationally Determining the Properties of Dark Matter [PDF]

, 1998
Determining the properties of the dark components of the universe remains one of the outstanding challenges in cosmology. We explore how upcoming CMB anisotropy measurements, galaxy power spectrum data, and supernova (SN) distance measurements can ...

Planetary influence on the young Sun's evolution: the solar neutrino probe

, 2013
Recent observations of solar twin stars with planetary systems like the Sun, have uncovered that these present a peculiar surface chemical composition. This is believed to be related to the formation of earth-like planets.
