Double Longitudinal Asymmetry in Jet k$_{t}$ Measured in Di-hadron Correlations in Polarized p+p Collisions at $\sqrt s $= 200GeV in the PHENIX Experiment at RHIC

By measuring the azimuthal correlations between two high p$_{t}$ hadrons, one can extract jet properties such as the fragmentation transverse momentum j$_{t}$ and the ``intrinsic'' transverse momentum k$_{t}$.~ In longitudinally polarized p+p collisions, differences in the extracted average k$_{t}$ for like and un-like helicity combinations (double asymmetry) may give information on the relationship between the polarization and the partonic transverse momentum, and thus the orbital angular momentum of the hard-scattered partons.~ This method is similar to a technique previously suggested by Meng Ta-chung et al. in the Drell-Yan channel.~ In this talk we present the physics technique, the analysis method and the current status of the analysis for $\pi ^{0}$ - hadron azimuthal correlations in PHENIX with data from RHIC in 2003, 2004 and 2005.
