The production of Z⁰ bosons in the reaction ep→eZ⁰p^(*), where p^(*) stands for a proton or a low-mass nucleon resonance, has been studied in ep collisions at HERA using the ZEUS detector. The analysis is based on a data sample collected between 1996 and 2007, amounting to 496pb^-1 of integrated luminosity. The Z⁰ was measured in the hadronic decay mode. The elasticity of the events was ensured by a cut on ηmax<3.0, where ηmax is the maximum pseudorapidity of energy deposits in the calorimeter defined with respect to the proton beam direction. A signal was observed at the Z⁰ mass. The cross section of the reaction ep→eZ⁰p^(*) was measured to be σ(ep→eZ⁰p^(*))=0.13±0.06(stat.)±0.01(syst.) pb, in agreement with the Standard Model prediction of 0.16 pb. This is the first measurement of Z⁰ production in ep collisions. © 2012 Elsevier B.V.
