The High-Luminosity Large Hadron Collider (HL-LHC) will operate at unprecedented luminosity, with substantial data boosts enhancing the search for new physics and precision measurements. This paper explores advancements in detector technology, novel search strategies, and cutting-edge analysis techniques aimed at maximizing the HL-LHC’s physics potential. We focus on the challenges of high pileup, precision measurements of Higgs boson properties, searches for physics beyond the Standard Model, and improvements in handling complex data with machine learning. Through these innovations, the HL-LHC will push the boundaries of our understanding in particle physics.
