Planck Scale Effects on the Majoron
E. Kh. Akhmedov, Z. G. Berezhiani, R. N. Mohapatra +1
The hypothesis that non-perturbative gravitational effects lead to explicit breaking of global symmetries is considered in the context of Majoron models. We find that the nonvanish…
17 keV neutrino and large magnetic moment solution of the solar neutrino puzzle
Eugeni Akhmedov, Zurab Berezhiani, Goran Senjanovic +1
Zee-type models with Majorons naturally incorporate the 17 keV neutrino but in their minimal version fail to simultaneously solve the solar neutrino puzzle. If there is a sterile n…
Planck scale effects in neutrino physics
Eugeni Akhmedov, Zurab Berezhiani Goran Senjanovic, Zhijian Tao
We study the phenomenology and cosmology of the Majoron (flavon) models of three active and one inert neutrino paying special attention to the possible (almost) conserved generaliz…
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…
