Description

Measurement of different quarkonia states is a well known tool for study of hot and dense matter produced in heavy ion collisions. The PHENIX experiment at RHIC have successfully measured chi_c production in p+p and d+Au collisions at 200 GeV. The chi_c decays were reconstructed through their decays to J/Psi+gamma. Results from the 2006 p+p and 2008 d+Au datasets at 200GeV will be presented. The accuracy and pT reach of these measurements potentially can be improved if one uses conversions of soft photons from chi_c decays to e+e- pairs. These pairs can be then detected by the VTX detector recently installed in PHENIX. We present a simulation study of such measurement, and comparison to existing measurements.
