DM induced neutron disappearance as the origin of the LZ nuclear recoil event
P. Uttayarat, J. Julio, R. Primulando
We investigate dark-matter-induced neutron disappearance as an interpretation of the high-energy nuclear recoil event reported by LUX-ZEPLIN. An incoming dark matter (DM) particle…
Identifying the origin of the 146-GeV excess at the LHC
P. Uttayarat, J. Julio, R. Primulando
The 146-GeV excess in the electron-muon final state reported by the CMS Collaboration offers a tantalizing hint for new physics. There are two competing explanations for the origin…
Constraining the new contributions to electron in a radiative neutrino mass model
Bayu Dirgantara, J. Julio
We examine electron and muon anomalous magnetic dipole moments within a radiative neutrino mass model featuring TeV-scale scalar leptoquarks and . We util…
Novel probes for electron-muon flavor violation from exotic Higgs decays
P. Uttayarat, J. Julio, R. Primulando
In this paper, we propose two novel signatures of Higgs decays to search for electron-muon flavor violation. These signatures arise from the presence of a light pseudoscalar into w…
A New Higgs Boson with Electron-Muon Flavor-Violating Couplings
R. Primulando, J. Julio, N. Srimanobhas +1
Recently, the CMS Collaboration performed a search on a new resonance decaying to in the mass range of 110 GeV to 160 GeV. The search also hints a possible excess at 1…
Minimal Zee model for lepton and -mass shifts
R. Primulando, J. Julio, P. Uttayarat
We present a unique Yukawa structure of the Zee model that can accommodate neutrino oscillation data, solves the muon problem, and explains the recent boson mass measur…
Marriage between neutrino mass and flavor anomalies
J. Julio, Shaikh Saad, Anil Thapa
Experimental hints for lepton flavor universality violation in beauty-quark decay both in neutral- and charged-current transitions require an extension of the Standard Model for wh…
A flavor-inspired radiative neutrino mass model
J. Julio, Shaikh Saad, Anil Thapa
One of the most important discoveries in particle physics is the observation of nonzero neutrino masses, which dictates that the Standard Model (SM) is incomplete. Moreover, severa…
Zee model with quasidegenerate neutrino masses and where to find it
R. Primulando, J. Julio, P. Uttayarat
We present a Zee model with a family dependent symmetry for radiative neutrino masses. Our motivation is to get a model that correctly describes neutrino oscillation phenomen…
Collider Constraints on a Dark Matter Interpretation of the XENON1T Excess
R. Primulando, J. Julio, P. Uttayarat
In light of the excess in the low-energy electron recoil events reported by XENON1T, many new physics scenarios have been proposed as a possible origin of the excess. One possible…
Collider Constraints on Lepton Flavor Violation in the 2HDM
R. Primulando, J. Julio, P. Uttayarat
In light of the recent CMS analysis on lepton flavor violating (LFV) heavy Higgs searches and updated bounds on various search channels involving neutral and charged scalars, we pr…
Scalar phenomenology in type-II seesaw model
R. Primulando, J. Julio, P. Uttayarat
In this work we study the viable parameter space of the scalar sector in the type-II seesaw model. In identifying the allowed parameter space, we employ constraints from low energy…
Predictive Model of Radiative Neutrino Masses
K. S. Babu, J. Julio
We present a simple and predictive model of radiative neutrino masses. It is a special case of the Zee model which introduces two Higgs doublets and a charged singlet. We impose a…
Constraining Higgs mediated dark matter interactions
Admir Greljo, J. Julio, Jernej F. Kamenik +2
We perform an analysis of Higgs portal models of dark matter (DM), where DM is light enough to contribute to invisible Higgs decays. Using effective field theory we show that DM ca…

K. S. Babu, J. Julio
A new model of radiative neutrino masses generated via two-loop diagrams is proposed involving a charge 2/3 vector-like quark and a doublet of leptoquark scalars. This model predic…

K. S. Babu, J. Julio, Yue Zhang
We study perturbative unitarity constraints on general W' models by considering the high energy behavior of fermion scattering into gauge bosons. In most cases we survey, a Z' boso…
Two-Loop Neutrino Mass Generation through Leptoquarks
K. S. Babu, J. Julio
We present a new model of radiative neutrino mass generation wherein TeV scale leptoguark scalars induce tiny neutrino masses as two-loop radiative corrections. The neutrino oscill…
