“…It also sports a very radially compact footprint, extending only a few cm, making it a very attractive solution for PID in this region. More detailed information about the physics goals of EIC experiments, as well as the designs of the JLab and BNL designs for the accelerator can be found in [1], [2], and [3]. The work presented in this article was done in collaboration with the PANDA Cherenkov Collaboration, who are concurrently working on a barrel DIRC for the PANDA experiment at the FAIR facility [4].…”

The proposed Electron-Ion Collider (EIC) will explore the physical regime of the most fundamental particles, quarks and gluons, and their interactions, which create 95% of the mass of the visible matter in the universe. To analyze these collisions a sophisticated particle ID system must be built. A detector based on Detection of Internally Reflected Chereknov light (DIRC) technology is an attractive and radially compact solution for charged particle identification (e/π, π/K, K/p) at an EIC in the barrel region not accessible by traditional RICH detectors. This article will describe the status of the design and R&D effort for a high performance DIRC envisioned for an EIC detector. The current design of the DIRC at EIC will use a new, innovative compound lens to reach remarkable resolution sufficient to extend the momentum coverage well beyond stateof-the-art, up to 6 GeV/c. Performance of a prototype of the compound lens on both test bench studies as well as in a CERN test beam will also be discussed.

“…Single transverse spin asymmetries for vector bosons in proton-proton collisions can thus serve as these purposes, i.e., to test the sign change on one side, and to constrain the sea quark Sivers function at the same time. The sea quark distribution will be further measured with high precision in a future electron ion collider [25][26][27].…”

We study the cross section for vector boson (W ± /Z 0 /γ * ) production in polarized nucleon-nucleon collisions for low transverse momentum of the observed vector boson. For the case where one measures the transverse momentum and azimuthal angle of the vector bosons, we present the cross sections and the associated spin asymmetries in terms of transverse momentum dependent parton distribution functions (TMDs) at tree level within the TMD factorization formalism. To assess the feasibility of experimental measurements, we estimate the spin asymmetries for W ± /Z 0 boson production in polarized proton-proton collisions at the Relativistic Heavy Ion Collider (RHIC) by using current knowledge of the relevant TMDs. We find that some of these asymmetries can be sizable if the suppression effect from TMD evolution is not too strong. The W program at RHIC can, thus, test and constrain spin theory by providing unique information on the universality properties of TMDs, TMD evolution, and the nucleon structure. For example, the single transverse spin asymmetries could be used to probe the well-known Sivers function f ⊥q 1T , as well as the transversal helicity distribution g q 1T via the parity-violating nature of W production.
