Higgs bosons with a boost

Dr. Jennet Dickinson
Research Associate

The discovery of the Higgs boson during the first run of proton-proton collisions at the Large Hadron Collider (LHC) supplied the final missingĀ  piece of the standard model of particle physics. Measurements of the Higgs boson and its interactions, especially at high energies, present the most promising avenue to discover new physics at the LHC. The decay of a Higgs boson to a bottom-antibottom quark pair - H(bb) - has historically been a challenging channel for precision measurements. However, developments in jet substructure and flavor tagging algorithms since the Higgs discovery have made H(bb) a powerful channel for studying the boosted hadronic jet topology that is characteristic of a high energy H(bb) decay. Tools for identifying boosted H(bb) events will be discussed, and the first simultaneous measurement of two Higgs boson production modes at high transverse momentum will be presented.
