Multi-strange baryon correlations in p+p and d+Au collisions at $\sqrt{s}=200$ GeV

Abstract

Multi-strange baryon correlations with charged hadrons have been measured in the p+p and d+Au reference systems at s^(0.5) = 200 GeV per nucleon pair, for future comparison with correlations in Au+Au collisions. Weak correlation peaks are observed on both the same side as the high pT (pT > 2 GeV/c) Xi (the trigger particle), and on the away side (pi radians away in azimuth) in the p+p data. A quantitative analysis requires better statistics than is presently available. Distinct peaks are also seen in PYTHIA simulations of p+p collisions, but spectra comparison between PYTHIA and data shows that PYTHIA does not reproduce the data. A clear correlation is also present in d+Au data, establishing a reference foundation for a future Au+Au study.
