Search for First Generation Leptoquarks in the $$e \nu j j$$ and $e e j j$ Decay Channels in $$p\bar{p}$$ Collisions at $$\sqrt{s}$$ = 1.8-TeV

The subject of this thesis is the search for first-generation scalar and vector leptoquarks produced in pairs in proton-antiproton collisions at a center-of-mass energy of 1.8 TeV and disintegrating in the channels "evjj" and " Eejj ". The analysis was carried out on the data collected by the CDF experiment during the period 1992-1995. The signature of the events sought is as follows: one energetic electron, two high-energy hadronic jets and transverse energy missing in channel "evjj" and two high-energy electrons, as well as two high-energy jets In the channel "eejj". No evidence of the signal is found. For each disintegration channel and for their combination, the lower limits on the leptoquarks mass were therefore determined at a confidence level of 95%
