Recent results on Central Exclusive Production with the STAR detector

We present results on the Central Exclusive Production of charged particle pairs h^{+}h^{-} h+h− ( h = \pi, K, p display="inline">h=π,K,p ), pp\to p^\prime+h^{+}h^{-}+p^\prime display="inline">pp→p′+h+h−+p′ , obtained with STAR experiment at RHIC in proton-proton collisions a center-of-mass energy \sqrt{s} 200 display="inline">s=200 ~GeV. All final-state particles were reconstructed, including forward-scattered protons detected Roman Pot system. As result, Double Pomeron Exchange (DPE) events selected and non-exclusive backgrounds efficiently rejected. Differential fiducial cross sections measured as functions observables related to central hadronic final state protons. The compared phenomenological model predictions based DPE. also preliminary measurement same physics process higher collision 510 display="inline">s=510 data demonstrate features similar those observed
