Reconstruction and Identification of High-Q2 Elastic ep Events at EicC

Understanding the internal structure of a proton remains a central objective of modern nuclear physics. Measurements of unpolarized elastic electron–proton scattering at high four-momentum transfer, Q2, provide essential input for determining proton electromagnetic form factors. The proposed Electron–Ion Collider in China (EicC), with its broad kinematic coverage and advanced detector capabilities, offers a promising opportunity to study elastic scattering in this kinematic region. In this work, we present a feasibility study of high-Q2 unpolarized elastic electron–proton scattering at EicC. Particular attention is given to the reconstruction of elastic events and the suppression of inelastic backgrounds using kinematic constraints, with the aim of assessing whether a clean elastic event sample can be obtained.
