Leptoquarks carry lepton number as well as baryon number and could provide an explanation for the observed symmetry between the quarks and leptons. Leptoquarks coupling to first-generation quarks and leptons were searched for in electron-protoncollisions at HERA using the ZEUS detector. In a sample of e~p —> v X events corresponding to an integrated luminosity of 27.5 nb- 1, no leptoquark candidates were found. Limits on leptoquark couplings are derived for leptoquark masses ranging from 50 G e V /c 2 to 2 2 5 G e V /c 2. Scalar (vector) isosinglet leptoquarks coupling to a left-h a n d e d electron and a u-quark (d -quark) with electroweak coupling strength are ruled out a t the 95% confidence level for masses below 154 G e V /c 2 (108 G e...
