Mass hierarchy, 2-3 mixing and CP-phase with Huge Atmospheric Neutrino Detectors
E. Kh. Akhmedov, Soebur Razzaque, A. Yu. Smirnov
We explore the physics potential of multi-megaton scale ice or water Cherenkov detectors with low ( GeV) threshold. Using some proposed characteristics of the PINGU detecto…
Neutrino oscillations: theory and phenomenology
E. Kh. Akhmedov
A brief overview of selected topics in the theory and phenomenology of neutrino oscillations is given. These include: oscillations in vacuum and in matter; phenomenology of 3-flavo…
A simple analytic three-flavour description of the day-night effect in the solar neutrino flux
E. Kh. Akhmedov, M. A. Tortola, J. W. F. Valle
In the 3-flavour framework we derive a simple approximate analytic expression for the day-night difference of the flux of solar at terrestrial detectors which is valid for an…
Solar neutrino oscillations and bounds on neutrino magnetic moment and solar magnetic field
E. Kh. Akhmedov, J. Pulido
If the observed deficit of solar neutrinos is due to neutrino oscillations, neutrino conversions caused by the interaction of their transition magnetic moments with the solar magne…
Neutrino oscillations beyond two flavours
E. Kh. Akhmedov
I review some theoretical aspects of neutrino oscillations in the case when more than two neutrino flavours are involved. These include: approximate analytic solutions for 3-flavou…
Neutrino masses and mixing with seesaw mechanism and universal breaking of extended democracy
E. Kh. Akhmedov, G. C. Branco, F. R. Joaquim +1
In the framework of a minimal extension of the SM, where the only additional fields are three right-handed neutrinos, we suggest that the charged lepton, the Dirac neutrino and the…
SNO and the neutrino magnetic moment solution of the solar neutrino problem
E. Kh. Akhmedov, J. Pulido
Assuming that the solar neutrino deficit observed in the Homestake, SAGE, Gallex, Kamiokande and Super-Kamiokande experiments is due to the interaction of the neutrino transition m…
Linking solar and long baseline terrestrial neutrino experiments
E. Kh. Akhmedov, G. C. Branco, M. N. Rebelo
We show that in the framework of three light neutrino species with hierarchical masses and assuming no fine tuning between the entries of the neutrino mass matrix, one can use the…
Seesaw mechanism and structure of neutrino mass matrix
E. Kh. Akhmedov, G. C. Branco, M. N. Rebelo
We consider the seesaw mechanism of neutrino mass generation in the light of our present knowledge of the neutrino masses and mixing. We analyse the seesaw mechanism constrained by…
Small entries of neutrino mass matrices
E. Kh. Akhmedov
We consider phenomenologically allowed structures of the neutrino mass matrix in the case of three light neutrino species. Constraints from the solar, atmospheric and reactor neutr…
Baryogenesis via neutrino oscillations
E. Kh. Akhmedov, V. A. Rubakov, A. Yu. Smirnov
We propose a new mechanism of leptogenesis in which the asymmetries in lepton numbers are produced through the CP-violating oscillations of ``sterile'' (electroweak singlet) neutri…
Pontecorvo's Original Oscillations Revisited
E. Kh. Akhmedov, S. T. Petcov, A. Yu. Smirnov
We show that a left-handed neutrino can oscillate into its - conjugated state with maximal amplitude, in direct analogy with oscillations. Pecul…
Planck-Scale Physics and Neutrino Masses
Eugeni Akhmedov, Zurab Berezhiani, Goran Senjanovic
We discuss gravitationally induced masses and mass splittings of Majorana, Zeldovich-Konopinski-Mahmoud and Dirac neutrinos. Among other implications, these effects can provide a s…
