Search For First Generation Leptoquark Pair Production In The Electron Missing Energy Jets Final State

Search for First Generation Leptoquark Pair Production in the Electron + Missing Energy + Jets Final State

We present a search for the pair production of first generation scalar leptoquarks (LQ) in data corresponding to an integrated luminosity of 5.4 fb-1 collected with the D0 detector at the Fermilab Tevatron Collider in pp collisions at √s = 1.96 TeV. In the channel LQLQ → eq?eq, where q,q are u or d quarks, no significant excess of data over background is observed, and we set a 95% C.L. lower limit of 326 GeV on the leptoquark mass, assuming equal probabilities of leptoquark decays to eq and ?subesubq.

International Europhysics Conference on High Energy Physics

The 1997 International Europhysics Conference on High Energy Physics was held at the campus of the Hebrew University of Jerusalem and at the Jerusalem Renaissance Hotel, from August 19th to August 25th, 1997. This was the first time that the European Physical Society had its High Energy Physics Conference outside the boundary of Europe. A total of 550 physicists participated in the conference with a total of 250 presentations in the parallel sessions and 26 presentations in the plenary sessions. The Board of the of the High Energy and Particle Physics division (HEPP) of the EPS acted as the Scientific Organizing Committee. The Board acknowl edges the help of the International Advisory Committee as well as that of the Local Organizing Committee. The conference was co-organized by the Hebrew University of Jerusalem and by the Weizmann Institute of Science, with important help by physi cists from the Israeli Institute of Technology (Technion) and the Tel Aviv University.
