abstract

In this paper we analyze spectra in the phenomenological supersymmetric Standard Model that simultaneously result in the right dark-matter relic density $\Omega_{\rm DM} h^2$, offer an explanation for the $(g-2)_{\mu}$ discrepancy $\Delta a_{\mu}$ and are minimally fine-tuned. We discuss the LHC phenomenology resulting from these spectra and the sensitivity of dark-matter direct detection experiments to these spectra. We find that the latter type of experiments with sensitivity to the spin-dependent dark-matter-nucleon scattering cross section $\sigma_{\rm SD,p}$ will probe all of our found solutions.

  1. A 95 GeV Higgs Boson in the $U(1)_X$SSM

    hep-ph 2024-11 reject novelty 5.0 of 10

    A light Higgs state in the U(1)_XSSM, made mostly of the η and ηbar singlet fields, can reproduce the 95 GeV γγ and bb excesses while keeping a 125.4 GeV SM-like Higgs.

  2. The Light Neutralino Dark Matter in the Generalized Minimal Supergravity (GmSUGRA)

    hep-ph 2025-01 conditional novelty 4.0 of 10

    In GmSUGRA, a light Higgsino-like neutralino dark matter at the Z and Higgs poles survives the LHC and LZ constraints only when the Higgsino mass parameter μ is negative.

  3. Electric dipole moments from the perspective of a scalar triplet and singlet extension of the MSSM: A study of neutrons, electrons, mercury, and b and c quarks

    hep-ph 2025-01 conditional novelty 4.0 of 10

    In the TNMSSM, the new CPV couplings χ_d and χ_t give significant contributions to EDMs, with neutron EDM data constraining their phases and b, c quark EDMs reaching 10^-22 and 10^-23 e·cm.
