In this talk I present findings for the measurement of a previously unconfirmed Standard Model (SM) process, providing further evidence that the electroweak sector of the SM is well behaved. In order to study more rare and exotic particle behavior at the LHC, SM background processes must be searched out, measured, and understood. To identify new signals, all of the backgrounds for a process must be understood, and one of the largest background sources remaining to be measured is a weakly produced single top quark produced in association with a Z boson. The measurement of such a process can be used in searches for flavor changing neutral currents as well as possible direct production of yet undiscovered particles. Here I present initial studies and results of such a search and measurement.
