Abstract: We calculated the relative abundances of charge hadron, KS0, Λ and Λ in the near-side and away-side cones correlated with triggered high pT 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-KS0 and －Λ+Λ correlations seem to be differet. We have used a double-Gaussian function to fit those correlation functions and compared the fit parameters.
