The minimum bias differential yield is reported for , , , and strange hadrons, obtained from collisions at RHIC energies of as a function of in kinematic range of and pseudorapidity region of using PYTHIA8 and HIJING2 event generators. The PYTHIA8 is tuned to different Colour Reconnection (CR) modes, and results are compared with STAR data at RHIC. PYTHIA8 predictions agree with STAR data at low values, while underestimate at high values.The observed deviations in CR0 are due to multiparton interactions, the deviations in CR1 are due to QCD effects. At low , the non-pQCD effects are dominant, while at high , the pQCD effects are dominant. The deviations in CR2 mode is due to the minimization of strings followed by different colour combinations, and the deviations in case of CR3 mode is connected with strings as viewed diagonally in extended bags. HIJING2 predictions explain the STAR data very well over the entire region.
