Comparative studies of 2HDMs under the Higgs boson precision measurements
Journal of High Energy Physics, 2021 We perform comparative studies for four types of the two Higgs Doublet Models (2HDMs) under the precision measurements of the Standard Model (SM) Higgs observables at the proposed Higgs factories.

Evidence for a Phenomenological Supersymmetry in Atomic Physics [PDF]
Physical Review Letters, 1984 We show that supersymmetric quantum mechanics may be used to interrelate the spectra of different atoms and ions. This supersymmetry is broken by electron-electron interactions.

Interference effects in t t ¯ $$ t\overline{t} $$ production at the LHC as a window on new physics
Journal of High Energy Physics, 2019 Many extensions of the Standard Model (SM) contain (pseudo)scalar bosons with masses in the TeV range. At hadron colliders, such particles would predominantly be produced in gluon fusion and would decay into top quark pair final sates, a signal that ...

Phenomenology of supersymmetry with broken R-parity [PDF]
Physics Letters B, 1985 In some phenomenological supersymmetric models R-parity (+1 for particles, -1 for sparticles) is spontaneously broken along with tau-lepton number Lτ by a vacuum expectation value υτ of the tau sneutrino ντ. To avoid excess stellar energy loss through majorons, there should also be explicit Lτ violation through right-handed neutrinos.

Dark matter, sparticle spectroscopy and muon (g − 2) in SU(4) c × SU(2) L × SU(2) R
Journal of High Energy Physics, 2018 We explore the sparticle mass spectra including LSP dark matter within the framework of supersymmetric SU(4) c × SU(2) L × SU(2) R (422) models, taking into account the constraints from extensive LHC and cold dark matter searches.

E6 motivated UMSSM confronts experimental data
Journal of High Energy Physics, 2020 We test E 6 realisations of a generic U(1)′ extended Minimal Supersymmetric Standard Model (UMSSM), parametrised in terms of the mixing angle pertaining to the new U(1)′ sector, θ E 6 $$ {\theta}_{E_6} $$ , against all currently available data, from ...

Analysis of the TeV-scale mirage mediation with heavy superparticles
Journal of High Energy Physics, 2017 We discuss effective models derived from a supersymmetric model whose mediation mechanism of supersymmetry (SUSY) breaking is namely mirage mediation.

A supersymmetric theory of baryogenesis and sterile sneutrino dark matter from B mesons
Journal of High Energy Physics, 2020 Low-scale baryogenesis and dark matter generation can occur via the production of neutral B mesons at MeV temperatures in the early Universe, which undergo CP-violating oscillations and subsequently decay into a dark sector.

Solving the muon g-2 anomaly in CMSSM extension with non-universal gaugino masses
Journal of High Energy Physics, 2018 We propose to generate non-universal gaugino masses in SU(5) Grand Unified Theory (GUT) with the generalized Planck-scale mediation SUSY breaking mechanism, in which the non-universality arises from proper wavefunction normalization with lowest component
