Precision Higgs and Precise Tracks

HEP Special Seminar

Abstract: As no new resonances have yet been observed at the LHC, precision measurements of Standard Model couplings are becoming an increasingly important probe of new physics.

I present a measurement of Higgs boson production in association with a leptonically decaying vector boson in events where the Higgs boson decays to a pair of W bosons. The measurement is based on a data sample of pp collisions collected with the CMS detector at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 137 fb−1. In addition to an inclusive measurement, the production cross sections are measured with respect to the vector boson transverse momentum, according to a simplified template cross sections framework. This offers particular sensitivity to higher-order effective field theory operators, particularly when combined with measurements in other final states.
