Abstract
We analyze PHENIX near-side ridge data for central Au+Au collisions at {sqrt}S_{NN} = 200 GeV. We find that the data can be described well by the momentum kick model. The systematics of the extracted parameters provide useful information on the magnitude of the momentum kick per jet-medium-parton collision, the number of jet-medium-parton collisions, and the momentum distribution of medium partons at the early stage of the nucleus-nucleus collision. We explore further the use of a photon jet to test models for the ridge phenomenon.
