Talk Title: "Revealing the secrets of the Higgs boson: progress and prospects" Abstract: In this talk, I will discuss two recent and unexpected advances by the CMS experiment in exploring the nature of the Higgs boson. I will begin with the first evidence for the rare Higgs boson decay to muons, achieved much earlier than had been expected by the LHC community largely due to the development of several novel analysis methods. This will be followed by a description of a set of innovative machine learning-based High Level triggers and state-of-the art event reconstruction algorithms that we developed for CMS data-taking during the LHC Run-3. I will show how these innovations are accelerating CMS’s multi-prong search program for the measurement of the Di-Higgs production rate, a key observable for probing the Higgs boson self-interaction.
