Abstract
The Central Exclusive Production (CEP) processes with Double Pomeron Exchange (DPE) in proton-proton collisions are particularly intriguing as they can generate the exclusive h+h- pair with an even spin and positive parity. This unique characteristic makes them an ideal environment for the exploration and discovery of glueball states. In this work, we will present results on CEP of charged hadron pairs h+h-(h = pi, K, p) measured with the STAR experiment at RHIC in proton-proton collisions at root s = 200 GeV and 510 GeV. The differential fiducial cross sections at root s = 200 GeV will be presented and compared to the theoretical calculations from DPE models. Structures observed in the mass spectra of pi(+)pi(-) and K+K- pairs were found consistent with the DPE model, while angular distributions of pions suggested a dominant spin-0 contribution to pi(+)pi(-) production. We also present preliminary results on the measurement of the same physics process at the higher root s = 510 GeV.
