The next frontier project of nuclear physics in United States will be the Electron-Ion Collider (EIC), planned to be built in the Brookhaven National Laboratory (BNL). Excellent particle identification (PID) is an essential requirement for the EIC central detector. Identification of the hadrons in the final state is critical to study how different quark flavors contribute to nucleon properties. A detector based on the Detection of Internally Reflected Cherenkov light (DIRC) principle, with a radial size of only a few cm, is a perfect solution for those requirements. The R&D program performed by the EIC PID collaboration (eRD14) is  focused on designing a high-performance DIRC (hpDIRC) that would extend the momentum coverage well beyond the state-of-the-art. Two alternative algorithms are being developed to o make optimum use of the observables and to determine the performance of the detector. Details and challenges of these algorithms and exciting news about EIC will be discussed.

Refreshments served at 3:45 PM
