We show that gauge coupling unification in SUSY models can make a non-trivial interconnection between collider and proton decay experiments. Under the assumption of precise gauge coupling unification in the MSSM, the low energy SUSY spectrum and the unification scale are intertwined, and the lower bound on the proton lifetime can be translated into upper bounds on SUSY masses. We found that the current limit on $\tau(p \to \pi^0 e^+)$ already excludes gluinos and winos heavier than $\sim 120… Expand

Detectable dimension-6 proton decay in SUSY SO(10) GUT at Hyper-Kamiokande
Abstract In the minimal SUSY SU(5) GUT with O(1) TeV SUSY particles and O(1) or below self-coupling for the GUT-breaking Higgs field, the width of the dimension-6 proton decay is suppressed belowExpand
Search for Supersymmetry in events with an isolated lepton, at least 2-9 jets and missing transverse momentum with the ATLAS detector
This thesis presents a search for the supersymmetric partners of quarks (squarks) and gluons (gluinos) in proton-proton collision events with exactly one electron or muon, multiple jets and missingExpand
