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.

Higgs Sector in Extensions of the MSSM [PDF]
, 2006 Extensions of the Minimal Supersymmetric Standard Model (MSSM) with additional singlet scalar fields solve the important mu-parameter fine tuning problem of the MSSM.

Constrained minimal Dirac gaugino supersymmetric standard model [PDF]
, 2014 We examine the possibilities for constructing models with Dirac gaugino masses and unification of gauge couplings. We identify one promising model, and discuss to what extent it can have a "natural SUSY" spectrum.

Supersymmetric Higgs singlet effects on FCNC observables [PDF]
, 2008 Higgs singlet superfields, usually present in extensions of the Minimal Supersymmetric Standard Model (MSSM) which address the $\mu$-problem, such as the Next-to-Minimal Supersymmetric Standard Model (NMSSM) and the Minimal Nonminimal Supersymmetric ...

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 ...

Naturalness and dark matter in the supersymmetric B-L extension of the standard model [PDF]
, 2017 We study the naturalness properties of the B−L supersymmetric standard model (BLSSM) with type-I seesaw and compare them to those of the minimal supersymmetric standard model (MSSM) at both low (i.e., Large Hadron Collider) energies and high (i.e ...

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

Journal of High Energy Physics, 2020 We study 3rd family Yukawa unification in the context of supersymmetric (SUSY) SO (10) GUTs and SO(10)-motivated boundary conditions for the SUSY-breaking soft terms.

Fine tuning in the constrained exceptional supersymmetric standard model [PDF]
, 2013 Supersymmetric unified models in which the Z ? couples to the Higgs doublets, as in the E 6 class of models, have large fine tuning dominated by the experimental mass limit on the Z ? .
