We present a study of the invariant mass spectra of jets in events with one identified lepton and missing transverse energy at the CDF II experiment at the Fermilab Tevatron. Events of this signature indicate the interface between electroweak and strong processes, and are critical to studies of vector boson production, top-quark physics, Higgs boson physics, and searches for beyond-the-standard-model particles. We present detailed analyses of several control regions which are used to calibrate detector response and models of instrumental background. Finally, using the full CDF data set, we search for high-mass resonances decaying into jets, and find no significant excess above the standard-model-background prediction.
