Resolving the Octant theta(23) Degeneracy by Neutrino Oscillation Experiments
Hiroshi Nunokawa
We discuss how and to what extent the degeneracy associated with theta(23), if it's not maximal, can be resolved by future oscillation experiments which utilize conventional neutri…
Resolving Eight-Fold Neutrino Parameter Degeneracy by Two Identical Detectors with Different Baselines
Takaaki Kajita, Hisakazu Minakata, Shoei Nakayama +1
We have shown in a previous paper that two identical detectors with each fiducial mass of 0.27 megaton water, one in Kamioka and the other in Korea, which receive the (anti-) muon…
NOvA and T2K: The race for the neutrino mass hierarchy
Olga Mena, Hiroshi Nunokawa, Stephen Parke
The determination of the ordering of the neutrino masses (the hierarchy) is probably a crucial prerequisite to understand the origin of lepton masses and mixings and to establish t…
Determining Neutrino Mass Hierarchy by Precision Measurements in Electron and Muon Neutrino Disappearance Experiments
H. Minakata, H. Nunokawa, S. J. Parke +1
Recently a new method for determining the neutrino mass hierarchy by comparing the effective values of the atmospheric Δm^2 measured in the electron neutrino disappearance channel,…
On the Mass Eigenstate Purity of B^8 Solar Neutrinos
Stephen Parke, Hiroshi Nunokawa, Renata Zukanovich Funchal
We give a brief report on our recent paper, hep-ph/0601198, in which we calculate the nu_2 mass eigenstate purity of B^8 solar neutrinos as 91 +/- 2 %.
What Fraction of Boron-8 Solar Neutrinos arrive at the Earth as a nu_2 mass eigenstate?
Hiroshi Nunokawa, Stephen Parke, Renata Zukanovich Funchal
We calculate the fraction of B^8 solar neutrinos that arrive at the Earth as a nu_2 mass eigenstate as a function of the neutrino energy. Weighting this fraction with the B^8 neutr…
