New physics explanations of a μ in light of the FNAL muon g − 2 measurement
Journal of High Energy Physics, 2021 The Fermilab Muon g −2 experiment recently reported its first measurement of the anomalous magnetic moment a μ FNAL $$ {a}_{\mu}^{\mathrm{FNAL}} $$ , which is in full agreement with the previous BNL measurement and pushes the world average deviation ∆ a ...

Less minimal supersymmetric standard model [PDF]
Physical Review D, 1999 Most of the phenomenological studies of supersymmetry have been carried out using the so-called minimal supergravity scenario, where one assumes a universal scalar mass, gaugino mass, and trilinear coupling at M_{GUT}. Even though this is a useful simplifying assumption for phenomenological analyses, it is rather too restrictive to accommodate a large ...

Minimal non-abelian supersymmetric Twin Higgs
Journal of High Energy Physics, 2017 We propose a minimal supersymmetric Twin Higgs model that can accommodate tuning of the electroweak scale for heavy stops better than 10% with high mediation scales of supersymmetry breaking.

Indirect probe of electroweakly interacting particles at the high-luminosity Large Hadron Collider
Journal of High Energy Physics, 2018 Many extensions of the standard model (SM) involve new massive particles charged under the electroweak gauge symmetry. The electroweakly interacting new particles affect various SM processes through radiative corrections.

Displaced vertex signatures of a pseudo-Goldstone sterile neutrino
Journal of High Energy Physics, 2021 Low-scale models of neutrino mass generation often feature sterile neutrinos with masses in the GeV-TeV range, which can be produced at colliders through their mixing with the Standard Model neutrinos.

Impact of an extra gauge interaction on naturalness of supersymmetry
Journal of High Energy Physics, 2018 It is pointed out that in supersymmetric models with a new gauge symmetry under which the Higgs is charged, the fine-tuning of the electroweak symmetry breaking is relaxed due to suppression of the top Yukawa coupling at higher scales by a new large ...

How heavy can neutralino dark matter be?
Journal of High Energy Physics, 2019 What is the upper limit of the mass of the neutralino dark matter whose thermal relic is consistent with the observation? If the neutralino dark matter and colored sparticles are extremely degenerated in mass, with a mass difference less than the QCD ...

Employing nucleon decay as a fingerprint of SUSY GUT models using SusyTCProton
Journal of High Energy Physics, 2021 While the observation of nucleon decay would be a smoking gun of Grand Unified Theories (GUTs) in general, the ratios between the decay rates of the various channels carry rich information about the specific GUT model realization.

Moderately suppressed dimension-five proton decay in a flipped SU(5) model
Journal of High Energy Physics, 2022 We study colored Higgsino-mediated proton decay (dimension-five proton decay) in a model based on the flipped SU(5) GUT. In the model, the GUT-breaking 10, 10 ¯ $$ \overline{\mathbf{10}} $$ fields have a GUT-scale mass term and gain VEVs through higher ...

Closing the window for compressed dark sectors with disappearing charged tracks
Journal of High Energy Physics, 2017 We investigate the sensitivity at current and future hadron colliders to a heavy electrically-charged particle with a proper decay length below a centimetre, whose decay products are invisible due to below-threshold energies and/or small couplings to the
