Swift observation of Segue 1: constraints on sterile neutrino parameters in the darkest galaxy
Swift observation constraints on sterile neutrino parameters
2011/1/10
Some extensions of standard particle physics postulate that dark matter may be partially composed of weakly interacting sterile neutrino particles that have so far eluded detection. We use a short (~5...
Field theory description of neutrino oscillations
Field theory description neutrino oscillations
2010/12/27
We review various field theory approaches to the description of neutrino oscillations in vacuum and external fields. First we discuss a relativistic quantum mechanics based approach which involves th...
Positronium signature in organic liquid scintillators for neutrino experiments
Positronium signature organic liquid scintillators neutrino experiments
2011/1/4
Electron anti-neutrinos are commonly detected in liquid scintillator experiments via inverse beta decay,by looking at the coincidence between the reaction products, neutron and positron. Prior to posi...

2011/1/6
It has been very recently reported (McKeen, Pospelov, arXive:1011.3046) that the parameter
region suggested for an explanation of the neutrino oscillation results from the LSND, KARMEN
and MiniBooNE...
In this paper, we investigate the effect of the presence of a quantum gravity induced minimal
length in neutrino oscillation probabilities.
In this paper, we investigate the effect of the presence of a quantum gravity induced minimal

Neutrino physics with an intense \nuc{51}{Cr}source and an array of low-energy threshold HPGe detectors
Neutrino physics an intense \nuc{51}{Cr}source an array of low-energy threshold HPGe detectors
2011/1/4
We study some of the physics potential of an intense $1\,\mathrm{MCi}$ $^{51}\mathrm{Cr}$ source combined with the {\sc Majorana Demonstrator} enriched germanium detector array. The {\sc Demonstrator}...
Dynamical neutrino masses in the generalized Chaplygin gas scenario with mass varying CDM
neutrino masses generalized Chaplygin gas scenario mass varying CDM
2010/11/10
Neutrinos coupled to an underlying scalar field in the scenario for unification of mass varying
dark matter and cosmon-like dark energy is examined. In the presence of a tiny component of mass varyin...
The pasta phase and its consequences on neutrino opacities

2010/11/16
In this paper, we calculate the diffusion coefficients that are related to the neutrino opacities considering the formation of nuclear pasta and homogeneous matter at low densities. Our results show t...
