Search for boosted Higgs decays to pairs of heavy quarks with the CMS Experiment — •Andrzej Novak, Xavier Coubez, Luca Mastrolorenzo, Spandan Mondal, and Alexander Schmidt — RWTH Aachen, Aachen, Germany

The Higgs boson decay into bottom quarks has the highest branching fraction of all decay modes. Among the not yet observed decays, the branching fraction to charm quarks is the second highest. This talk presents a search for the Higgs boson in the gluon fusion production mode with high Lorentz boosts, decaying to a pair of bottom quarks. The analysis has been published in 2018 and was sensitive enough to observe the boosted Z boson decay into b quarks for the first time. Given the recently developed deep learning based tools for identification of bottom and charm flavor jets in such topologies, the natural next step is an analogous search for the decay to a pair of charm quarks. Probing this channel is not only important for completeness and studying the Higgs couplings to the second generation of fermions, but it could also be sensitive to potential beyond Standard Model corrections.
