Studies for EIC physics performance and detector design

The high-luminosity high-energy Electron-Ion Collider (EIC) to be built at Brookhaven National Laboratory (BNL) will provide a clean environment to address several fundamental questions including studying the proton/nuclear structure, understanding the proton spin origin, searching for gluon saturation and exploration of matter formation in the high energy and nuclear physics fields. A high granularity detector, which can determine the collision vertex, identify particle species and decay vertex, and measure track momentum and particle energy with high precision is desired. Recent detector and physics developments for the EIC project detector include the EIC yellow report preparation, the detector reference design selection and detector optimization led by the newly formed ePIC collaboration. The current ePIC detector design consists of vertex, tracking, particle identification, electromagnetic calorimeter and hadronic calorimeter subsystems to realize a series of hadron and jet measurements in the pseudorapidity region of |η| ≤ 3.5. Progresses and results of the EIC project detector physics and detector studies will be discussed in this talk.
