Theory of Neutrinos: A White Paper
R. N. Mohapatra, S. Antusch, K. S. Babu +29
During 2004, four divisions of the American Physical Society commissioned a study of neutrino physics to take stock of where the field is at the moment and where it is going in the…
Constraining Mass Spectra with Sterile Neutrinos from Neutrinoless Double Beta Decay, Tritium Beta Decay and Cosmology
Srubabati Goswami, Werner Rodejohann
We analyze the constraints on neutrino mass spectra with extra sterile neutrinos as implied by the LSND experiment. The various mass related observables in neutrinoless double beta…
Improved Limit on theta_{13} and Implications for Neutrino Masses in Neutrino-less Double Beta Decay and Cosmology
M. Lindner, A. Merle, W. Rodejohann
We analyze the impact of a measurement, or of an improved bound, on theta_{13} for the determination of the effective neutrino mass in neutrino-less double beta decay and cosmology…
The See-Saw Mechanism, Neutrino Yukawa Couplings, LFV Decays l_i to l_j + gamma and Leptogenesis
S. T. Petcov, W. Rodejohann, T. Shindou +1
The LFV charged lepton decays mu to e + gamma, tau to e + gamma and tau to mu + gamma and thermal leptogenesis are analysed in the MSSM with see-saw mechanism of neutrino mass gene…
Flavor Symmetry L_mu - L_tau and quasi-degenerate Neutrinos
W. Rodejohann, M. A. Schmidt
Current data implies three simple forms of the neutrino mass matrix, each corresponding to the conservation of a non-standard lepton charge. While models based on L_e and L_e - L_m…
Neutrinoless Double Beta Decay and Future Neutrino Oscillation Precision Experiments
S. Choubey, W. Rodejohann
We discuss to what extent future precision measurements of neutrino mixing observables will influence the information we can draw from a measurement of (or an improved limit on) ne…
Broken mu-tau Symmetry and Leptonic CP Violation
R. N. Mohapatra, W. Rodejohann
We propose that leptonic CP violation arises from a breaking of the mu-tau exchange symmetry in the neutrino mass matrix which in turn is indicated by the near maximal atmospheric…
Deviations from Tribimaximal Neutrino Mixing
F. Plentinger, W. Rodejohann
Current neutrino data are consistent with the so-called tribimaximal mixing scenario, which predicts \sin^2 θ_{12}=1/3, zero U_{e3} and maximal θ_{23}. This implies a special form…
Minimal Mass Matrices for Dirac Neutrinos
C. Hagedorn, W. Rodejohann
We consider the possibility of neutrinos being Dirac particles and study minimal mass matrices with as much zero entries as possible. We find that up to 5 zero entries are allowed.…
