Narrow Results

Fundamental questions concerning the strong interaction are addressed by the PANDA experiment at the future FAIR facility at GSI-Darmstadt. PANDA will be a general purpose detector of modular design optimized to measure the interaction of an antiproton beam with proton and heavy nuclear targets. The physics program at PANDA covers a wide range of topics including gluonic excitations, spectroscopy of strange and charm mesons, Drell-Yan and CP violating processes. This contribution focuses on the part of the physics program dealing with antiproton - proton annihilation.

The present status and future plans of the physics program of Central Exclusive Production (CEP) at RHIC are described. The measurements are based on the detection of the forward protons from the Double Pomeron Exchange (DPE) process in the Roman Pot system and of the recoil system of charged particles from the DPE process measured in the STAR experiment's Time Projection Chamber (TPC). The data described here were taken using polarized proton–proton collisions at . The preliminary spectra of two-pion mass reconstructed by STAR TPC in central region of pseudorapidity |η| < 1, are presented. Near future plans to take data with the current system at center-of-mass energy and plans to upgrade the forward proton tagging system are presented. Also a possible addition of the RPs to the sPHENIX detector is discussed.
