Subcritical regime of hybrid inflation with modular A 4 symmetry
Abstract We consider a supergravity model that has the modular A 4 symmetry and discuss the interplay between the neutrino mixing and inflation. The model contains right- handed neutrinos that have the Majorana masses and additional Yukawa couplings to the waterfall field. In the model an active neu...
