Measurement of jet fragmentation in p + p collision at sqrt(s) = 200 GeV with the PHENIX detector

Abstract

Measurement of jet fragmentation property in p + p collisions provides a crucial baseline for the study of a possible, modified fragmentation behavior at the presence of the quark-gluon plasma. We describe the first measurement of jet fragmentation functions in sqrt(s) = 200 GeV p + p collisions at RHIC. This is facilitated by extending the linear least square unfolding technique employed by high energy and nuclear experiments to multidimensional spectra, which allows us to correct the inefficiencies in the jet energy response encountered at detectors such as PHENIX.
