Abstract

In the year 2005 run PHENIX has accumulated 3.8 pb^-1 integrated luminosity in longitudinally polarized p+p collisions at √(s)=200 GeV. Double helicity asymmetries of neutral pions lead to restrictions of the gluon polarization in the proton. Also, transverse single spin asymmetries of charged hadrons have been measured with comparable statistical accuracy of the 2002 run in considerably less time.
