The future circular $e^+ e^-$ collider (FCC-ee) stands out as the next flagship project in particle physics, dedicated to uncovering the microscopic origin of the Higgs boson. In this context, we assess indirect probes of the Minimal Supersymmetric Standard Model (MSSM), a well-established benchmark hypothesis, exploring the complementarity between Higgs measurements and electroweak precision tests at the $Z$-pole. We study three key sectors: the heavy Higgs doublet, scalar top partners, and light gauginos and higgsinos, focusing on the parameter space favored by naturalness. Remarkably, the Tera-$Z$ program consistently offers significantly greater indirect sensitivity than the Mega-$h$ run. While promising, these prospects hinge on reducing SM uncertainties. Accordingly, we highlight key precision observables for targeted theoretical work.

  1. When Two Loops Matter: Electroweak Precision in the SMEFT

    hep-ph 2026-04 unverdicted novelty 7.0

    A modification to the top-Higgs Yukawa coupling in SMEFT induces a two-loop shift in the W mass through a large anomalous dimension, providing a new indirect probe via electroweak precision observables.

  2. Complementary Probes of Light Higgsinos: Electroweak Precision Measurements and Dark Matter Direct Detection

    hep-ph 2026-06 unverdicted novelty 5.0

    Future electroweak precision measurements can probe light higgsinos up to 500 GeV even in compressed spectra below the neutrino fog, complementing direct detection which reaches the 1 TeV thermal relic mass.
