Fate of under Reflection Symmetry in Light of the First JUNO Results
Ranjeet Kumar
The recent Jiangmen Underground Neutrino Observatory (JUNO) measurements of and open a new avenue for probing flavor symmetric structures in the lepton sector.…
Minimal A4 Type-II Seesaw Realization of Testable Neutrino Mass Sum Rules
Salvador Centelles Chuliá, Ranjeet Kumar
We propose a flavour model based on an symmetry combined with a type-II seesaw mechanism for neutrino mass generation. The resulting neutrino mass matrix obeys a sum rule tha…
Gravitational Wave Symphony from Oscillating Spectator Scalar Fields
Yanou Cui, Pankaj Saha, Evangelos I. Sfakianakis
We investigate a generic source of stochastic gravitational wave background due to the parametric resonance of oscillating scalar fields in the early Universe. By systematically an…
Dark photon and dark mediated meson decays
Alakabha Datta, A. Hammad, Danny Marfatia +2
We study flavor changing neutral current decays of and mesons in the dark model, with the dark photon/dark mass between 10 MeV and 2 GeV. Although the model pr…
Disentangling the high and low cutoff scales via the trilinear Higgs couplings in the type-I two-Higgs-doublet model
Sin Kyu Kang, Jinheung Kim, Soojin Lee +1
The type-I two-Higgs-doublet model in the inverted Higgs scenario can retain the theoretical stability all the way up to the Planck scale. The Planck-cutoff scale, $Λ_{\rm cut}^{\r…

A. Hammad, Myeonghun Park, Raymundo Ramos +1
We demonstrate two sampling procedures assisted by machine learning models via regression and classification. The main objective is the use of a neural network to suggest points li…
N-jettiness for muon jet pairs in electroweak high-energy processes
Junegone Chay, Taehyun Kwon
We study the -jettiness in the electroweak high-energy process for the final muon jet pairs, . Compared to QCD, the ma…
Kinematic Variables and Feature Engineering for Particle Phenomenology
Roberto Franceschini, Doojin Kim, Kyoungchul Kong +3
Kinematic variables have been playing an important role in collider phenomenology, as they expedite discoveries of new particles by separating signal events from unwanted backgroun…
Confronting the prediction of leptonic Dirac CP-violating phase with experiments
Yang Hwan Ahn, Sin Kyu Kang, Raymundo Ramos +1
We update and improve past efforts to predict the leptonic Dirac CP-violating phase with models that predict perturbatively modified tribimaximal or bimaximal mixing. Simple pertur…

Yang Hwan Ahn, Sin Kyu Kang, Raymundo Ramos
We present the implications of the recent measurement of boson at CDF II on the two-Higgs-doublet model (2HDM). In the analysis, we impose theoretical bounds such as vacuum sta…

Stefan Antusch, Oliver Fischer, A. Hammad +1
Extended scalar sectors with additional degrees of freedom appear in many scenarios beyond the Standard Model. Heavy scalar resonances that interact with the neutral current could…
