Gravitational waves from supermassive right-handed neutrinos produced at preheating
Shinya Kanemura, Kunio Kaneta, Dibyendu Nanda
The post-inflationary production of supermassive particles can have profound implications for the thermal history of the universe and may leave observable imprints in the gravitati…
Bounds and detection of MeV-scale dark matter annihilation to neutrinos
Shinya Kanemura, Shao-Ping Li, Dibyendu Nanda
Current and most upcoming neutrino detectors can only reach a dark matter annihilation cross section to neutrinos larger than the standard freeze-out value, but they open intriguin…
Viability of post-inflationary freeze-in with precision cosmology
Anirban Biswas, Sougata Ganguly, Dibyendu Nanda +1
Prediction of inflationary observables from the temperature fluctuation of Cosmic Microwave Background (CMB) can play a pivotal role in predicting the reheating dynamics in the ear…
Effective theory of light Dirac neutrino portal dark matter with observable
Debasish Borah, Satyabrata Mahapatra, Dibyendu Nanda +2
We study the possibility of light Dirac neutrino portal dark matter (DM) in an effective field theory setup. Dirac nature of light neutrino automatically includes its right chiral…
Phenomenology of Dirac neutrino EFTs up to dimension six
Anirban Biswas, Eung Jin Chun, Sanjoy Mandal +1
The gauge-singlet right-handed neutrinos would be essential to explain the tiny masses of active neutrinos. We consider the effective field theory of the Standard Model extended wi…
Vector Dark Matter with Higgs Portal in Type II Seesaw framework
Nandini Das, Tapoja Jha, Dibyendu Nanda
We study the phenomenology of a vector dark matter (VDM) in a gauged extension of the Standard Model (SM) which is connected to the type II seesaw framework via the Higgs…
