Derives a three-parameter diffusion model from Nekhoroshev theorem that fits LHC beam dynamics experimental results with high accuracy.
New correlated observables from the (P_Higgs, θ_Zγ) plane with XGBoost improve H→Zγ signal discrimination from Z/γ* background, raising S/B to 2.1% (electrons) and 3.4% (muons) near the Higgs mass.
The average muon detection efficiency of 137 CMS GE1/1 triple-GEM chambers was measured at 93.3% using 2023 collision data, with defect-free chambers reaching ~96%, confirming readiness for HL-LHC operation.
Fully heavy pentaquark fragmentation functions PQ5Q1.0 are completed for charm and bottom flavors and used to compute NLL/NLO+ semi-inclusive production rates at future colliders.
