Event Details

The measurement of W boson pair production is an important test of the electroweak gauge sector standard model (SM) of particle physics. Extending the measurement to include the properties of associated jets is a further test of quantum chromodynamics that has not been performed before in events with multiple heavy gauge bosons. This process is a significant background for Higgs boson studies in the W+W- decay mode at particle colliders where the use of jet vetos and jet counting is an essential element of the analysis technique. Dr. Parker will briefly discuss the search for the Higgs boson at CDF, focusing on the W+W- channel, before presenting the new CDF W+W- cross section measurement. The cross section has been measured inclusively and differentially as a function of jet energy and multiplicity, compared to current fixed order and next to leading order Monte Carlo predictions. This is the first measurement of associated jet properties in a massive diboson state, uniquely possible at the Tevatron due to reduced top quark pair production background relative to the LHC.
