The SPASCHARM project is aimed at studying a fundamental problem of modern particle physics, such as the mechanism of spin asymmetries in the production of hadrons. The goal of the first stage of the SPASCHARM experiment at the U-70 accelerator in Protvino is the study of single-spin asymmetry in different reactions using negative pion beam with a polarized proton target. SPASCHARM setup was commissioned and will start data taking this fall. Second stage of the SPASCHARM experiment will measure spin effects using polarized proton and antiproton beams.
The specific task of this talk is to study possibility to measure single-spin asymmetry in inclusive production of K⁰s and ω (782) mesons at negative pion and polarized antiproton beams. The measurement of inclusive production of K⁰s and ω (782) mesons with polarized antiproton beam are planning for the first time. Expected statistic accuracies of single-spin asymmetry in inclusive production of K⁰s and ω (782) mesons are presented. The expected accuracy is 1-2% in different kinematic regions.
