Review of the empirical evidence for superluminal particles and the model of the neutrino masses
A review is given of hypothetical faster-than-light tachyons and the
development of the author's model of the neutrino mass states, which
includes one tachyonic mass state doublet. Published empirical evidence for the
model is summarized, including an interpretation of the mysterious Mont Blanc
neutrino burst from SN 1987A as being due to tachyonic neutrinos having
This possibility requires an 8 MeV antineutrino line from SN
1987A, which a new dark matter model has been found to support. Furthermore,
this dark matter model is supported by several data sets: rays from
the galactic center, and the Kamiokande-II neutrino data on the day of SN
1987A. The KATRIN experiment should serve as the unambiguous test of the
model and its tachyonic mass state
Lepton-pair Cerenkov radiation emitted by tachyonic neutrinos: Lorentz-covariant approach and IceCube data
Current experiments do not exclude the possibility that one or more neutrinos
are very slightly superluminal or that they have a very small tachyonic mass.
Important bounds on the size of a hypothetical tachyonic neutrino mass term are
set by lepton pair Cerenkov radiation (LPCR), i.e., by the decay channel nu ->
e^+ e^- nu which proceeds via a virtual Z0 boson. Here, we use a
Lorentz-invariant dispersion relation which leads to very tight constraints on
the tachyonic mass of neutrinos; we also calculate decay and energy loss rates.
A possible cutoff seen in the IceCube neutrino spectrum for E_nu > 2 PeV, due
to the potential onset of LPCR, is discussed.Comment: 7 pages; accepted for publication in the Advances of High-Energy

Evidence for two neutrino mass eigenstates from SN 1987A and the possibility of superluminal neutrinos
This paper reports a new phenomenological analysis of the neutrino burst
detected from SN 1987 A, and it reveals the presence of two mass eigenstates.
The heavier mass eigenstate has , while the lighter
one has . It is not the first paper to make such a
claim, but it expands on a 1988 conditional analysis by Cowsik, and it attempts
to make the evidence more robust through an improved statistical analysis, and
through providing reasons why alternative explanations are unlikely. It also
shows how the result can be made consistent with existing smaller electron
neutrino mass limits with the existence of a third tachyonic (superluminal)
mass eigenstate.Comment: 11 pages, 2 figure
A Universal Hurricane Frequency Function
Evidence is provided that the global distribution of tropical hurricanes is
principally determined by a universal function H of a single variable z that in
turn is expressible in terms of the local sea surface temperature and latitude.
The data-driven model presented here carries stark implications for the large
increased numbers of hurricanes which it predicts for a warmer world. Moreover,
the rise in recent decades in the numbers of hurricanes in the Atlantic, but
not the Pacific basin, is shown to have a simple explanation in terms of the
specific form of H(z), which yields larger percentage increases when a fixed
increase in sea surface temperature occurs at higher latitudes and lower
temperatures.Comment: In press with "Advances in Meteorology
