Abstract

We present the inclusive and identified particle (pion, proton and their\nantiparticle) production in Single Diffraction Dissociation and Central\nDiffraction processes with the STAR detector at RHIC. The forward-scattered\nproton(s) are tagged in the STAR Roman Pot system while the charged particle\ntracks are reconstructed in the STAR Time Projection Chamber. Ionization energy\nloss and time of flight of charged particles are used for particle\nidentification. In addition, the proton-antiproton production asymmetry as a\nfunction of rapidity is measured and used to study the baryon number transfer\nover a large rapidity interval in Single Diffraction Dissociation.\n
