Performance Analysis of Higgs Decays to Four Leptons Using Staco and Muid Algorithms

This study investigates the performance of Staco and Muid algorithms for the reconstruction of Higgs boson decays, specifically analyzing the decay channel H → 4l. Utilizing a dataset of 4000 events from PythiaH130zz4l simulations, we examine the invariant mass distributions of combinations involving loose and medium electrons, as well as muons. We evaluate the effectiveness of different identification strategies for muons and electrons, and we present findings on the reconstructed Higgs mass from various lepton configurations, shedding light on algorithmic performance in particle physics.
