Split Majoron model confronts the NANOGrav signal and cosmological tensions
P Di Bari, MH Rahat - Physical Review D, 2024 - APS
In the light of the evidence of a gravitational wave background from the NANOGrav 15 yr
dataset, we reconsider the split Majoron model as a new physics extension of the standard …
