Asymmetry measurement of charged hadron production in pA collisions at 40 GeV

Abstract

The single spin asymmetry of charge hadron production by a 40 GeV/c proton beam with 39% transverse polarization incident on nuclei (C, Cu) has been measured using the Focusing Double Arm Spectrometer (FODS). The measurements were carried out for hadrons with high Xt (82 deg. in c.m.) and with high Xf (one arm at 51 deg. and the other arm at 99 deg. in c.m.). The results are presented for charged pions, kaons, protons and antiprotons with high Xt.
