Search for First Generation Scalar Leptoquark Pairs in pp Collisions at √s=1.8TeV
Search for First Generation Scalar Leptoquark Pairs in pp Collisions at √s=1.8TeV
 
  We have searched for first generation scalar leptoquark (LQ) pairs in the eν+jets channel using pp collider data (∫Ldt≈115pb−1) collected by the D0 experiment at the Fermilab Tevatron during 1992–1996. The analysis yields no candidate events. We combine the results with those from the ee+jets and νν+jets channels to obtain 95% confidence level (C.L.) upper limits on the LQ pair production cross section as a function of mass and of β, the branching fraction to a charged lepton. Comparing with the next-to-leading order theory, we set 95% C.L. lower limits on the LQ mass of 225, 204, and 79GeV/c2 for β=1, 1/2, and 0, respectively.

          Abstract
          We have searched for first generation scalar leptoquark (LQ) pairs in the eν+jets channel using pp collider data (∫Ldt≈115pb−1) collected by the D0 experiment at the Fermilab Tevatron during 1992–1996. The analysis yields no candidate events. We combine the results with those from the ee+jets and νν+jets channels to obtain 95% confidence level (C.L.) upper limits on the LQ pair production cross section as a function of mass and of β, the branching fraction to a charged lepton. Comparing with the next-to-leading order theory, we set 95% C.L. lower limits on the LQ mass of 225, 204, and 79GeV/c2 for β=1, 1/2, and 0, respectively.
