We present results on the inclusive and identified (pion, kaon, proton and their antiparticles) charged-particle production in single diffractive (SD) dissociation process in proton-proton collisions at \sqrt{s}=200 s = 200 GeV with the STAR detector at RHIC. The forward-scattered proton is measured in the Roman Pot (RP) system, while the charged particle tracks are reconstructed in the STAR Time Projection Chamber. The proton-antiproton production asymmetry is measured to study the baryon number transfer over a large rapidity interval in SD process. In addition, K/\pi K / π ratio is measured, showing a larger strangeness production at p_T>0.5 p T > 0.5 GeV/ \mathit{c} compared to measurements in inclusive proton-proton collisions.
