Probing Leptophobic Dark Sectors via Gravitational Wave Signatures
Taramati, Lekhika Malhotra, Zafri A. Borboruah +1
We study a minimally extended version of the Standard Model where baryon number is gauged with a symmetry. This model can be made anomaly-free by adding a set of additiona…
Left-Right Symmetric Neutrino Mass Model without Scalar Bi-doublet
Zafri A. Borboruah, Lekhika Malhotra, Utkarsh Patel +2
We consider a left-right symmetric model with an and an scalar doublet but without the scalar bidoublet. The charged fermion masses in this model are generated…
Inflationary Gravitational Waves and Laboratory Searches as Complementary Probes of Right-handed Neutrinos
Zafri A. Borboruah, Frank F. Deppisch, Anish Ghoshal +1
We analyze the damping of inflationary gravitational waves (GW) that re-enter the Hubble horizon before or during a post-inflationary era dominated by a meta-stable, right-handed n…
Minimal Dirac seesaw dark matter
Zafri Ahmed Borboruah, Debasish Borah, Lekhika Malhotra +1
We propose a minimal Type-I Dirac seesaw which accommodates a thermal scalar dark matter (DM) candidate protected by a charge conjugation symmetry in dark sector , wi…
Inflationary Gravitational Wave Spectral Shapes as test for Low-Scale Leptogenesis
Zafri A. Borboruah, Anish Ghoshal, Lekhika Malhotra +1
We study non-thermal resonant leptogenesis in a general setting where a heavy majoron decays to right-handed neutrinos (RHNs) whose further out-of-equilibrium decay generates t…
Cogenesis of visible and dark sector asymmetry in a minimal seesaw framework
Utkarsh Patel, Lekhika Malhotra, Sudhanwa Patra +1
Recently there is a renewed interest in exploring the Dark sector of the universe in a more constrained way. Particularly in [1], the FIMP ( Feebly Interacting Massive Particle) sc…
