Entanglement Signatures of Kinetic-Mixing Portals in Dark Monopole Scattering
Shilpa Jangid, Hiroshi Okada
We examine the interaction between the Standard Model (SM) fermions and the topological dark magnetic monopoles mediated via a kinetic-mixing portal to investigate the generation o…
A radiative seesaw model in a non-invertible selection rule with the assistance of a non-holomorphic modular symmetry
Shilpa Jangid, Hiroshi Okada
We propose a two-loop neutrino mass model where fermionic and bosonic dark matter (DM) candidates are simultaneously connected to the neutrinos. But the fermionic DM candidate is f…
Finite-temperature stability from doublet inflation field with right-handed neutrinos
Seong Chan Park, Shilpa Jangid
We study the augmentation of the Standard Model (SM) with another Higgs doublet and right-handed neutrinos. The second Higgs doublet () is defined to be odd under the…
A natural realization of inverse seesaw model in a non-invertible selection rule
Shilpa Jangid, Hiroshi Okada
We propose natural hierarchies among neutral fermions in a framework of inverse seesaw, imposing a Tambara-Yamagami fusion rule which is applied to our phenomenology. Under t…
Strongly electroweak phase transition with gauged non-zero hypercharge triplet
Shilpa Jangid, Anirban Biswas, Seong Chan Park
This article considers three non-zero hypercharge triplets as an extension of the Standard Model Higgs doublet. Under extra symmetry, the triplets are charged. We…
Investigating two-zero texture in the light of gauged Type-II seesaw
Anirban Biswas, Shilpa Jangid, Seong Chan Park
Neutrino oscillation, discovered over two decades ago, confirmed that neutrinos have nonzero masses. Since then, two mass-squared differences have been measured with unprecedented…
Neutrino Mass Model and Dark Matter with Inert Triplet Scalar
Shilpa Jangid, Keiko I. Nagao, Hiroshi Okada
We study a one-loop induced neutrino mass model with an inert isospin triplet scalar field of and heavier isospin doublet vector-like leptons and singlet Majorana right-hande…
Electroweak phase transition with radiative symmetry breaking in Type-II seesaw with inert doublet
Shilpa Jangid, Hiroshi Okada
We consider the Type-II seesaw model extended with another Higgs doublet, which is odd under the symmetry. We look for the possibility of triggering the electroweak symmetry…
Exploring CP-violation in inert triplet with real singlet
Shilpa Jangid, Hiroshi Okada
In this article, we examine the Standard Model extended with a Higgs triplet and a real singlet. We consider the Higgs triplet to be odd under the symmetry, and hence t…
Constraining Scalar Doublet and Triplet Leptoquarks with Vacuum Stability and Perturbativity
Priyotosh Bandyopadhyay, Shilpa Jangid, Anirban Karan
We investigate the constraints on the leptoquark Yukawa couplings and Higgs-leptoquark quartic couplings for scalar doublet leptoquark , scalar triplet leptoquark $\ve…
Discerning Singlet and Triplet scalars at the electroweak phase transition and Gravitational Wave
Priyotosh Bandyopadhyay, Shilpa Jangid
In this article we examine the prospect of first order phase transition with a Y=0 real triplet extension of the Standard Model, which remains odd under , considering…
Scrutinizing Vacuum Stability in IDM with Type-III Inverse seesaw
Priyotosh Bandyopadhyay, Shilpa Jangid, Manimala Mitra
We consider the extension of the Standard Model (SM) with an inert Higgs doublet that also contains two or three sets of triplet fermions with hypercharge zero and analyz…
Distinguishing Inert Higgs Doublet and Inert Triplet Scenarios
Shilpa Jangid, Priyotosh Bandyopadhyay
In this article we consider a comparative study between Type-I 2HDM and , triplet extensions having one -odd doublet and triplet that render the desired dark matt…
Vacuum Stability in Inert Higgs Doublet Model with Right-handed Neutrinos
Shilpa Jangid, Priyotosh Bandyopadhyay, P. S. Bhupal Dev +1
We analyze the vacuum stability in the inert Higgs doublet extension of the Standard Model (SM), augmented by right-handed neutrinos (RHNs) to explain neutrino masses at tree level…
