A large portion of the universe is made from baryons (such as protons and neutrons), yet there are many open questions regarding their structure. When attempting to look at baryon structure, more specifically the production of negatively charged cascades, there are four methods one may choose: 1) photoproduction; 2) production with a kaon beam; 3) production with a pion beam; and 4) electroproduction. In this thesis the latter, electroproduction, is examined. While the cascades’ structure is related to that of the proton and neutron, its excited states are more easily separated from one another. The facility used for data collection is at the Thomas Jefferson National Accelerator Facility in Newport News, Virginia. Unfortunately, the run chosen for this data mining experiment did not have enough data to produce a distinguishable peak above the background signal. The upper bound estimate of the the cross section of the electroproduction process p(e,e’K + K +)Ξ − is estimated to be less than ∼ 10 nb, based on the cross section for the photoproduction process p(γ,K + K +)Ξ −. Where 1 barn = 10−28m 2 . The size of the cross section is the relative probability of this process occurring in relative to all other processes that are possible.
