Flavon vacuum alignment beyond SUSY
Claudia Hagedorn, M. L. López-Ibáñez, M. Jay Pérez +2
In flavor models the vacuum alignment of flavons is typically achieved via the -terms of certain fields in the supersymmetric limit. We propose a method for preserving such alig…
Primordial non-Gaussianity as a probe of seesaw and leptogenesis
Chee Sheng Fong, Anish Ghoshal, Abhishek Naskar +2
We present the possibility that the seesaw mechanism and nonthermal leptogenesis can be {investigated} via primordial non-Gaussianities in the context of a majoron curvaton model.…
The split majoron model confronts the NANOGrav signal and cosmological tensions
Pasquale Di Bari, Moinul Hossain Rahat
In the light of the evidence of a gravitational wave background from the NANOGrav 15yr data set, we reconsider the split majoron model as a new physics extension of the standard mo…
NANOGrav signal from axion inflation
Xuce Niu, Moinul Hossain Rahat
Several pulsar timing arrays including NANOGrav, EPTA, PPTA, and CPTA have recently reported the observation of a stochastic background of gravitational wave spectrum in the nano-H…
Towards distinguishing Dirac from Majorana neutrino mass with gravitational waves
Stephen F. King, Danny Marfatia, Moinul Hossain Rahat
We propose a new method towards distinguishing the Dirac versus Majorana nature of neutrino masses from the spectrum of gravitational waves (GWs) associated with neutrino mass gene…
Gravitational waves from phase transitions and cosmic strings in neutrino mass models with multiple majorons
Pasquale Di Bari, Stephen F. King, Moinul Hossain Rahat
We explore the origin of Majorana masses within the majoron model and how this can lead to the generation of a distinguishable primordial stochastic background of gravitational wav…
