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…
Collider Signatures of boson in the Alternative Left-Right Model
Mariana Frank, Chayan Majumdar, Poulose Poulose +2
Alternative Left-Right Models offer an attractive option to left-right models. Emerging from grand unification, these models are consistent with light scalars which do not in…
Gravitational wave signature of generic disappearance of -symmetry breaking domain walls
Piyali Banerjee, Urjit A. Yajnik
Breaking of discrete parity at high scale gives rise to -domain walls (DW). The metastability of such walls can make them relatively long lived and contradict standard cosmolo…
Dark Matter in the Alternative Left Right Model
Mariana Frank, Chayan Majumdar, Poulose Poulose +2
The Alternative Left-Right Model is an attractive variation of the usual Left-Right Symmetric Model because it avoids flavour-changing neutral currents, thus allowing the additiona…
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…
Determining neutrino mass hierarchy in an extended Left-Right model
Prativa Pritimita, Urjit A. Yajnik, Nitali Dash +1
We derive the lower bound on absolute scale of lightest neutrino mass for normal hierarchy and inverted hierarchy pattern of light neutrinos by studying the new physics contributio…
