Strange and Multi-Strange Particle Production in P+P Collisions at $\sqrt{s}$=200 Gev in Star

We present measurements of the transverse momentum spectra for K0s, Lambda, Xi and their antiparticles in p+p collisions at $\sqrt{s}=200$ GeV. The extracted mid-rapidity yields and <pT> are in agreement with previous $p+\bar{p}$ experiments while they have smaller statistical errors. We compa...

description We present measurements of the transverse momentum spectra for K0s, Lambda, Xi and their antiparticles in p+p collisions at $\sqrt{s}=200$ GeV. The extracted mid-rapidity yields and <pT> are in agreement with previous $p+\bar{p}$ experiments while they have smaller statistical errors. We compare the measured particle spectra and <pT> values to predictions from the PYTHIA leading order pQCD model (v6.221) and see significant disagreements with the default settings. Finally we compare the spectra to the latest calculations from NLO pQCD and see a good agreement for the K0s, but large discrepancies Lambda.
