Neutrino masses, vacuum stability and quantum gravity prediction for the mass of the top quark

G Domènech, M Goodsell, C Wetterich - Journal of High Energy Physics, 2021 - Springer
A bstract A general prediction from asymptotically safe quantum gravity is the approximate
vanishing of all quartic scalar couplings at the UV fixed point beyond the Planck scale. A …

Resonant leptogenesis in (2, 2) inverse see-saw realisation

I Chakraborty, H Roy, T Srivastava - Nuclear Physics B, 2022 - Elsevier
In this present work we uphold the standard model (SM) augmented with two right-handed
(RH) neutrinos along with two singlet neutral fermions to generate active neutrino masses …

Searches for heavy neutrinos at multi-TeV muon collider: a resonant leptogenesis perspective

I Chakraborty, H Roy, T Srivastava - The European Physical Journal C, 2023 - Springer
In this work, the Standard Model (SM) is extended with two right-handed (RH) neutrinos and
two singlet neutral fermions to yield active neutrino masses via (2, 2) inverse see-saw …

[HTML][HTML] Scalar Triplet Leptogenesis with a CP violating phase

S Chongdar, S Mishra - Nuclear Physics B, 2023 - Elsevier
We study baryogenesis through leptogenesis via decay of triplet scalars embedded in the
Standard Model. We consider two triplets scenario where the vacuum expectation value …

Confronting cosmic ray electron and positron excesses with hybrid triplet Higgs portal dark matter

SL Chen, AD Banik, ZK Liu - Chinese Physics C, 2022 - iopscience.iop.org
We perform a detailed study of scalar dark matter with triplet Higgs extensions of the
Standard Model in order to explain the cosmic ray electron and positron excesses reported …

[HTML][HTML] SU (5) unification of two triplet seesaw and leptogenesis with dark matter and vacuum stability

MK Parida, R Samantaray - Nuclear Physics B, 2021 - Elsevier
We investigate unification prospects of two heavy scalar triplet extension of the standard
model where, in the absence of any right-handed neutrino (RHN), type-II seesaw accounts …
