Supersymmetric standard models on D-branes [PDF]

Physics Letters B, 2001
Type IIB superstring models with the standard model gauge group on D3-branes and with massless matter associated with open strings joining D3-branes to D3-branes or D3-branes to ${\rm D}7_3$-branes are studied. Models with gauge coupling constant unification at an intermediate scale between about $10^{10}$ and $10^{12}$GeV and consistency with the ...

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

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 ...

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 ? .

THE MINIMAL SUPERSYMMETRIC STANDARD MODEL [PDF]

Modern Physics Letters A, 1996
The structure of the MSSM is reviewed. We first motivate the particle content of the theory by examining the quantum numbers of the known standard model particles and by the requirement of anomaly cancellation. Once the particle content is fixed we can write down the most general renormalizable superpotential.

Baryogenesis, dark matter and inflation in the next-to-minimal supersymmetric standard model [PDF]

, 2013
A bstractExplaining baryon asymmetry, dark matter and inflation are important elements of a successful theory that extends beyond the Standard Model of particle physics. In this paper we explore these issues within Next-to-Minimal Supersymmetric Standard

Probing new electroweak states via precision measurements at the LHC and future colliders

Journal of High Energy Physics, 2019
Several new physics scenarios, motivated e.g. by dark matter, feature new electroweakly charged states where the lightest particle in the multiplet is stable and neutral.

Comparatively light extra Higgs states as signature of SUSY SO(10) GUTs with 3rd family Yukawa unification

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.

Time-delayed electrons from neutral currents at the LHC

Journal of High Energy Physics, 2021
We investigate long-lived particles (LLPs) produced in pair from neutral currents and decaying into a displaced electron plus two jets at the LHC, utilizing the proposed minimum ionizing particle timing detector at CMS. We study two benchmark models: the
