摘要：
We present the inclusive and identified particle (pion, proton and their antiparticle) production in Single Diffraction Dissociation and Central Diffraction processes with the STAR detector at RHIC. The forward-scattered proton(s) are tagged in the STAR Roman Pot system, while the charged particle tracks are reconstructed in the STAR Time Projection Chamber. Ionization energy loss and time of flight of charged particles are used for particle identification. In addition, the proton-antiproton production asymmetry as a function of rapidity is measured and used to study the baryon number transfer over a large rapidity interval in the Single Diffraction Dissociation.
