Additional studies of the anomalous l+MET+2,3 jet events observed by CDF

We present additional studies of the kinematics of the anomalous events observed by the CDF experiment. These events contain a high-$p_T$ lepton, large transverse missing energy ($\MET$), and 2 or 3 high-$E_T$ jets, one of which contains both a displaced secondary vertex and a soft lepton. Previous articles detailed the selection and the kinematic properties of these events. In the present paper, we use several phenomenological approaches to model these data and to estimate their production cross section.
