Abstract
A search for any resonant state coupled to an electron and a proton constituent has been performed using collision of electron and proton beams at HERA. In a sample with integrated luminosity of 26 nb{sup -1}, no evidence has been found for production of leptoquarks with decays to e{sup -}+jet or {nu}+jet. Limits on the coupling strength of scalar leptoquarks to electron and quark have been determined for masses above 25 GeV. For example, scalar isosinglet leptoquarks (S{sub o}) with electroweak coupling strength to (e{sup -}u) states are ruled out at the 95% confidence level for masses below 168 GeV for left-handed couplings and below 176 GeV for right-handed couplings.
