We compute the gluino lifetime and branching ratios in Split Supersymmetry. Using an effective-theory approach, we resum the large logarithmic corrections controlled by the strong gauge coupling and the top Yukawa coupling. We find that the resummation of the radiative corrections has a sizeable numerical impact on the gluino decay width and branching ratios. Finally, we discuss the gluino decays into gravitino, relevant in models with direct mediation of supersymmetry breaking.

  1. Search for long-lived particles using displaced vertices with low-momentum tracks in proton-proton collisions at $\sqrt{s}$ = 13 TeV

    hep-ex 2025-11 conditional novelty 6.0

    A displaced-vertex search for compressed-spectrum long-lived particles excludes top squarks up to about 1100 GeV and wino-like neutralinos up to about 550 GeV, the strongest limits on these benchmark models.

  2. Induced-Gravity Palatini-Like Higgs Inflation in Supergravity Confronts ACT DR6

    hep-ph 2026-02 conditional novelty 5.0

    A Palatini-supergravity Higgs-inflation model with induced gravity predicts a scalar spectral index ns≈0.972-0.974, consistent with ACT DR6, and favors split supersymmetry with gravitino mass 40-60 PeV.

  3. Induced-Gravity Palatini-Like Higgs Inflation in Supergravity Confronts ACT DR6

    hep-ph 2026-02 unverdicted novelty 4.0

    A Palatini-inspired induced-gravity inflation model in supergravity fits ACT DR6 data while embedding into a B-L extended MSSM with split SUSY and leptogenesis.
