Physics
Researched and analyzed the efficiencies of resistive plate chambers of the CMS experiment using the CMS official computational tools (CMSSW and ROOT). She researched the background to the Higgs to ZG channel decay and improved the search for Higgs by decaying to two muons by recovering photons of final radiation. Also designed software for H2Mu group using traditional identification and search, through preselected cuts and selections; and implemented multivariate analysis techniques, machine learning, and decision trees for the identification and reconstruction of particles.
