Abstract

A summary of recent results from ZEUS is presented. New ZEUS results from HERA-1 data include Structure Functions, QCD fits, analysis of hadronic final states, precision measurements of alpha_s, production of heavy flavor mesons and baryons and studies of diffraction. Results from the new HERA-II running include the measurement of the cross section for polarized charged current events and charm events tagged with the new ZEUS vertex detector.
