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…
