Investigation of initial Antiproton Polarization — •Vincent Verhoeven for the P371 collaboration — Ruhr-University Bochum — GSI

The preparation of a polarized antiproton beam, useful for experiments aiming at exploring new physics topics, remains a challenge. No simple and efficient polarization method has yet been established. The CERN P371 experiment aims to investigate whether antiprotons produced in a high-energy proton beam collision with an unpolarized solid target are initially polarized. The polarization can be determined by measuring the asymmetry of elastic pp-scattering with a known analyzing power in the Coulomb-Nuclear Interference region. The experiment was carried out in July and August 2025 using the T11 beam line of the Proton Synchroton in the East Area. As a track reconstruction is required even to determine the number of antiprotons in the beam, the data analysis is challenging and currently ongoing.
