Neutrino Phenomenology of gauged L_mu - L_tau: MINOS and beyond

Julian Heeck, Werner Rodejohann

If a Z' gauge boson from a gauged L_mu - L_tau symmetry is very light, it is associated with a long-range leptonic force. In this case the particles in the Sun create via mixing of…

Recycling of Neutron Stars in Common Envelopes and Hypernova Explosions

Maxim V. Barkov, Serguei S. Komissarov

In this paper we propose a new plausible mechanism of supernova explosions specific to close binary systems. The starting point is the common envelope phase in the evolution of a b…

Rapid TeV variability in Blazars as result of Jet-Star Interaction

Maxim V. Barkov, Felix A. Aharonian, Sergey V. Bogovalov +2

We propose a new model for the description of ultra-short flares from TeV blazars by compact magnetized condensations (blobs), produced when red giant stars cross the jet close to…

Testing the Bimodal/Schizophrenic Neutrino Hypothesis in Neutrinoless Double Beta Decay and Neutrino Telescopes

James Barry, Rabindra N. Mohapatra, Werner Rodejohann

The standard assumption is that all three neutrino mass states are either Dirac or Majorana. However, it was recently suggested by Allaverdi, Dutta and one of the authors (R.N.M.)…

Charge-starved, relativistic jets and blazar variability

John G. Kirk, Iwona Mochol

High energy emission from blazars is thought to arise in a relativistic jet launched by a supermassive black hole. The emission site must be far from the hole and the jet relativis…
