Update on pPPG. What is new. Unidentified charged tracks in muon arms are analyzed. Results are compared with Identified hadrons. Fitting method is used to extract jet yield. There are two details, 1.) In d+Au, the away side width is fixed by p+p.

What is new • Unidentified charged tracks in muon arms are analyzed. Results are compared with Identified hadrons. • Fitting method is used to extract jet yield. There are two details, • 1.) In d+Au, the away side width is fixed by p+p. • 2.) In d+Au, the away side width is not fixed. • Comparison between fitting method and counting method.
Selection of unidentified charged tracks • chi2 < 20 • depth > 0 • DG0 < 20 cm • nhits > 12 • angle between station1 hit position vector and station1 momentum • theta_xp < 0.03 radian.

What next • There is no more statistic! We have to finger out a way to present the data best. E.g. Do we use the fitting or counting( more robust)? do we need to split more bins in centrality and pt ? • PYTHIA, I will do it ASAP. • Draft ? Discussion with theorist has to be done.
