Particle correlation in p+p collision √sNN=200 GeV in PYTHIA
We calculated the relative abundances of charge hadron,KOS,Λ and (Λ) in the near-side and awayside cones correlated with triggered high pт particles in minimum bias in p+p collisions at √sNN = 200 GeV in the PYTHIA model.From the quark and gluon jet events in the PYTHIA model,we have found that the particle yields different splitting.So the di-hadron correlation in the quark jet events and gluon jet events are also presented.And the particle charge dependance of the di-hadron correlation is extracted from the PYTHIA model.The di-hadron plus and di-hadron minus correlations are similar in the near-side (Δφ～0),but in the away-side,the di-hadron minus correlation seems to be lower.The Hadron-KOS and -Λ + (Λ) correlations seem to be differet.We have used a double-Ganssian function to fit those correlation functions and compared the fit parameters.
