"A hunt for elusive Higgs couplings, with a boost"

Cristina Mantilla , Fermilab
[Host: Craig Group]

Higgs bosons produced at high momentum are rare, but measurable. The tails of their kinetic spectrum can provide a unique insight on whether anomalous interactions exist at the TeV scale. The production of Higgs boson pairs is even rarer - about 1000 times less frequent- but it can be enhanced in some new physics models, particularly when the pairs are produced at high momentum. This talk reviews how final states with jets have enabled the exploration of these elusive and possibly anomalous couplings, even in a difficult collider environment that is full of quarks and gluons like the Large Hadron Collider. We examine advances on particle jet identification that have drastically improved our ability to identify boosted Higgs and increased our physics reach. Finally, I will talk about how calorimetry detectors need more spatial precision, greater radiation tolerance, and smarter readout electronics to ensure that this and other search programs can continue at the upcoming High-Luminosity LHC run.
