Photon-jet coincidence measurements in polarized pp collisions at sqrt{s}=200 GeV with the STAR Endcap Calorimeter

Abstract
Recent inclusive measurements with polarized proton-proton collisions at RHIC provide significant constraints on the polarized gluon distribution, Delta g(x), integrated over the gluon momentum range 0.02 < x < 0.3. Di-jet and photon-jet coincidence measurements will allow to study the x-dependence of Delta g(x). In this report we present the status of photon-jet coincidence studies for photons detected at forward pseudorapidity, 1.08<eta<2, using the STAR Endcap Calorimeter.
