Neutrino and antineutrino quasielastic interactions with nuclei
Neutrino antineutrino nuclei
2010/3/16
We investigate the interaction of neutrinos and antineutrinos with nuclei. We explore in particular the role played by the multinucleon excitations which can contaminate the quasielastic cross section...
Atmospheric neutrino oscillation analysis with sub-leading effects in Super-Kamiokande I, II, and III
Atmospheric neutrino oscillation sub-leading effects
2010/3/15
We present a search for non-zero theta_{13} and deviations of sin^2 theta_{23} from 0.5 in the oscillations of atmospheric neutrino data of Super-Kamiokande -I, -II, and -III. No distortions of the ne...
First Measurement of the Muon Neutrino Charged Current Quasielastic Double Differential Cross Section
Charged Current Quasielastic neutrino oscillations
2010/3/15
A high-statistics sample of charged-current muon neutrino scattering events collected with the MiniBooNE experiment is analyzed to extract the first measurement of the double differential cross sectio...
Neutrino masses and Neutrinoless Double Beta Decay: Status and expectations
Neutrino masses double beta decay
2010/3/15
Two most outstanding questions are puzzling the world of neutrino Physics: the possible Majorana nature of neutrinos and their absolute mass scale. Direct neutrino mass measurements and neutrinoless d...
Further study of neutrino oscillation with two detectors in Kamioka and Korea
neutrino oscillation Kamioka Korea
2010/3/15
This paper updates and improves the study of electron neutrino appearance in the framework of two far detectors at different oscillation maxima, specifically, Tokai-To-Kamioka-to-Korea. We used a like...

2010/3/22
We present calculations showing that upcoming Cosmic Microwave Background (CMB) experiments will have the power to improve on current constraints on neutrino masses and provide new limits on neutrino ...
A new multi-dimensional general relativistic neutrino hydrodynamics code for core-collapse supernovae. I. Method and code tests in spherical symmetry
general relativistic core-collapse supernovae neutrino hydrodynamics code
2010/3/19
We present a new general relativistic (GR) code for hydrodynamic supernova simulations with neutrino transport in spherical and azimuthal symmetry (1D/2D). The code is a combination of the CoCoNuT hyd...
Neutrino oscillations: Quantum mechanics vs. quantum field theory
Neutrino oscillations Quantum mechanics
2010/3/15
A consistent description of neutrino oscillations requires either the quantum-mechanical (QM) wave packet approach or a quantum field theoretic (QFT) treatment. We compare these two approaches to neut...
Parameter Degeneracy in Neutrino Oscillation -- Solution Network and Structural Overview
Parameter Degeneracy Neutrino Oscillation Solution Network
2010/3/15
It is known that there is a phenomenon called "parameter degeneracy" in neutrino oscillation measurement of lepton mixing parameters; A set of the oscillation probabilities, e.g., P(nu_mu --> nu_e) an...
Neutrino oscillation phase dynamically induced by f(R)-gravity
Neutrino mass and mixing Non-standard-model neutrinos Modified theories of gravity
2010/3/18
The gravitational phase shift of neutrino oscillation can be discussed in the framework of f(R)-gravity. We show that the shift of quantum mechanical phase can depend on the given f(R)-theory that we ...
Neutrino oscillations with a polarized laser beam: an analogical demonstration experiment
Neuteino oscillation birefringence demonstration experiment
2010/3/15
The underlying physics of neutrino oscillation in vacuum can be demonstrated by an optical analogical experiment. Two different neutrino flavors are represented by two polarization states of a laser b...

Neutrino oscillation data strongly support mu-tau symmetry as a good approximate flavor symmetry of the neutrino sector, which has to appear in any viable theory for neutrino mass-generation. The mu-t...

In this paper, we first discuss the detection of supernova neutrinos on earth. Then we propose a possible method to acquire information about θ13 smaller than 1.5° by detecting the ratio of the event ...
A summary of the current status of neutrino oscillations is given. We also include a brief description of the earlier development of neutrino physics and illustrate the roles that neutrinos play in se...
