Highlights from ZEUS

TL;DR

This paper summarizes recent results from the ZEUS experiment at HERA, focusing on high momentum transfer measurements with polarized leptons, their impact on QCD and electroweak fits, and ongoing challenges in understanding hadronic final states.

Contribution

It presents new high-Q^2 DIS measurements with polarized leptons and explores their implications for QCD and electroweak theory, including previously unmeasured hadronic states.

Findings

High-Q^2 DIS measurements with polarized leptons

Impact on combined QCD and electroweak fits

Identification of previously unmeasured hadronic final states

Abstract

Highlights from the ZEUS experiment at HERA as of the DIS06 conference in April are shown. New results focus on measurements from the HERA II running period of inclusive DIS at high momentum transfer using polarised leptons and on their impact in combined QCD and electroweak fits. Investigation of the hadronic final state, both for inclusive and diffractive reactions, continues to challenge theory. These are discussed as well as some previously unmeasured hadronic final states.
