Acceptance effects in the hyperons global polarization measurement

Abstract

The possible sources of systematic uncertainties in the hyperons global polarization measurement are discussed. The equation with detector acceptance effects taken into account is provided. Contribution of the hyperons directed flow into the hyperons global polarization measurement is shown. The systematic uncertainties of the Lambda hyperons global polarization measurement in Au+Au collisions with the STAR detector at RHIC are calculated.
