Analyzing power in inclusive + and production at high xF with a 200 GeV polarized proton beam Academic Article uri icon


  • The analyzing power in inclusive charged pion production has been measured using the 200 GeV Fermilab polarized proton beam. A striking dependence in xF is observed in which AN increases from 0 to 0.42 with increasing xF for the + data and decreases from 0 to -0.38 with increasing xF for - data. The kinematic range covered is 0.2xF0.9 and 0.2pT2.0 GeV/c. In a simple model our data indicate that at large xF the transverse spin of the proton is correlated with that of its quark constituents. 1991.
