Study of Hadronic Final States in Z Production in Searches for Monojet Signatures at the Tevatron

We present a comprehensive review of hadronic final states in $Z$ boson production in $\rm p\bar{\rm p}$ collisions at $\sqrt{s} = 1.96$ TeV. The analysis is performed in the context of preliminary studies on irreducible backgrounds in searches for monojet signatures, based on $\sim 1 \ {\rm fb^{-1}}$ of data collected by the CDF experiment in Run 2.
