Gravitational Wave Probe of Singlet-Doublet Dark Matter Induced Radiative Neutrino Mass
Ujjal Kumar Dey, Santu Kumar Manna, Partha Kumar Paul +2
We investigate an one loop radiative neutrino mass model, where the loop particles, notably a singlet fermion (), a doublet fermion () and three generations of singlet scal…

From Symmetry Breaking to Majoron Cosmology: Insights from NANOGrav 15-year Data
Tathagata Ghosh, Kousik Loho, Sudip Manna
We study the cosmology of a modified majoron model motivated by the need to protect a global symmetry from gravity-induced hard explicit breaking (by operators) a…

Gravitational Wave Signature and the Nature of Neutrino Masses: Majorana, Dirac, or Pseudo-Dirac?
Sudip Jana, Sudip Manna, Vishnu P. K
The fermionic nature of neutrinos and the origin of their tiny masses remain unresolved issues in particle physics, intrinsically connected to lepton number symmetry-conserved for…
