This thesis outlines the first measurement of CCQE neutral hyperon production cross section in a liquid argon time projection chamber (LArTPC) through a topological study [1] and presents the ongoing progress of the addition of a calorimetric study. The analysis uses 1.20 £ 1020 protons-on-target, in the NuMI beam operating in the low energy antineutrino mode. The results of the topological study provide a total cross section measurement at the mean production energy of 3.42 GeV for CCQE neutral hyperons. The result of the topological study is consistent with the NUANCE cross section model and sets a 90% confidence level on the upper limit of the cross section. The calorimetric study is ongoing and shows promise to provide additional results to compare with results of the topological study [1]. The progress and further steps are presented in this thesis.
