The Run 1a Analysis

This analysis is described in our 2nd generation prl. The D0 experiment has published mass limits for muon type scalar leptoquarks using the data collected between 1992 and 1993. We reported a lower limit of 111 GeV/c^2 for the muon-type LQ if beta=1. The limit is reduced to 89 GeV/c^2 if beta=0.5.
