RICH detector development for the Electron–Ion Collider experiments

Abstract

Abstract In the proposed Electron–Ion Collider (EIC) experiments, particle identification (PID) of the final state hadrons in semi-inclusive deep inelastic scattering allows the measurement of flavor-dependent gluon and quark distributions inside nucleons and nuclei. The EIC PID consortium (eRD14 Collaboration) has been formed for identifying and developing PID detectors using ring imaging Cherenkov (RICH) techniques for the future EIC experiments in a broad kinematic coverage. In this article, we summarize the recent work of the eRD14 Collaboration on three RICH detector systems: DIRC, dual radiator RICH, and compact modular RICH.
