SUMMARY:Naturalness Demands an Answer: The Imperative of Natural SUSY 
 at the HL-LHC\, Thesis Defense\, Kairui Zhang\, Physics PhD Graduate S
 tudent
DESCRIPTION:We explore the ramifications of natural supersymmetry (nat
 SUSY) frameworks for upcoming experiments at the high-luminosity Large
  Hadron Collider (HL-LHC). Specifically\, we scrutinize the production
  and subsequent decay modes of heavy SUSY Higgs bosons\, both neutral 
 and charged\, as well as stop pairs and electroweakino pairs\, within 
 the context of natural SUSY. The study highlights the importance of de
 cay hierarchy and the potential existence of a light higgsino for accu
 rate interpretation of LHC data. A detailed examination reveals that t
 he dominant decay modes of heavy winos to Standard Model bosons—W\, 
 Z\, or h—alongside light higgsinos with weak-scale masses\, emerge a
 s a unique signature of the natural SUSY paradigm. The investigation d
 elineates both the discovery and exclusion limits for these heavy SUSY
  particles\, thereby offering critical insights into the viability and
  constraints of natural SUSY models in the forthcoming LHC runs.
