An overview of the progress preparing the Electron-Ion Collider (EIC) for construction. The presentation addresses the EIC design requirements, conceptual design, and construction schedule. Current efforts to promote international engagement and collaboration will be described, including opportunities for contributions to the design and construction of the accelerators and collaboration on...
The design of the electron-ion collider (EIC) at Brookhaven National Laboratory
is well underway, aiming at a peak electron-proton luminosity of 10^34 cm^-2
sec^-1. This high luminosity and wide center-of-mass energy range from 29 to
141 GeV (e-p) require innovative solutions to maximize the performance of the
machine, which makes the EIC one of the most challenging accelerator...
Understanding the properties of nuclear matter and its emergence through the underlying partonic structure and dynamics of quarks and gluons requires a new experimental facility in hadronic physics known as the Electron-Ion Collider (EIC).
The EIC will address some of the most profound questions concerning the emergence of nuclear properties by precisely imaging gluons and quarks inside...
On behalf of the ePIC Collaboration
The future Electron-Ion Collider (EIC) at Brookhaven National Laboratory will collide polarized electrons with polarized proton/ions. The electron Proton and Ion Collider (ePIC) detector is being designed as the day one EIC detector. The EIC physics program requires precision tracking and particle identification (PID) capabilities that extend over a large...
The ePIC detector is being designed as a general-purpose detector for the Electron-Ion Collider (EIC) to deliver the full physics program. One of the key challenges at the EIC is particle identification (PID), which requires excellent separation of pions, kaons, and protons over a wide phase space with significant pion/electron suppression. To address this challenge, ePIC utilises multiple...
This talk will cover some of the electromagnetic calorimetry plans for the ePIC detector with a concentration on the design of the central barrel calorimeter based on the current GlueX BCAL at JLab. The requirements (as specified in the ePIC Project) include energy resolution of 10%/$\sqrt{E} \oplus (2-3)$% and electron-pion suppression great than $10^3$, which will be comfortably met by a...
Generalized Parton Distributions (GPDs) are nowadays the object of an intense effort of research, in the perspective of understanding nucleon structure. They describe the correlations between the longitudinal momentum and the transverse spatial position of the partons inside the nucleon and they can give access to the contribution of the orbital momentum of the quarks and gluons to the nucleon...
Beam polarimetry will play an important role in meeting the goals of the planned EIC physics program. However, the EIC beam properties will make achieving the level of precision required challenging for both electron and hadron beam polarimetry.
In this talk, I will give a brief overview of the techniques used to measure electron and hadron beam polarization at high energies, and discuss...
Precise measurements of the electron-hadron cross sections are the corner stone of scientific program at the future Electron-Ion Collider, hence the high demands towards the EIC luminosity measurements – at least a 1% accuracy is required for the absolute luminosity determination and only a 0.01% uncertainty for the relative, bunch-to-bunch, luminosity measurements. As was demonstrated at HERA...
The investigation of nucleon elastic electromagnetic form factors (EMFFs) at large momentum transfer has generated a large and increasing amount of experimental and theoretical interest over the last several decades. EMFFs provide precision benchmarks for theoretical modeling of nucleon structure and ab initio predictions in lattice QCD. Additionally, precise knowledge of the form factors at...
The transversity distribution function of quarks, $h_1^{q}(x)$, encapsulates the transverse spin structure of the proton at leading twist, where $x$ represents the longitudinal momentum fraction carried by the quark $q$. Extracting $h_1^{q}(x)$ poses a formidable challenge due to its chiral-odd nature. Measurements of final-state hadron pairs in transversely polarized proton-proton...
During the past several decades a large quantity of high-quality mesonic photo- and electro-production data have been measured at electromagnetic facilities worldwide. By contrast, meson-beam data for these same final states are mostly outdated, largely of poorer quality, or even non-existent, especially those involving spin asymmetries and polarizations. Thus, existing meson beam results...
In its report, the DPAP observed that ``there is significant support in the community and from the panel for a second general-purpose detector system to be installed in IR8 when resources are available.'' Such a detector would unlock the full discovery potential of the EIC by providing cross checks of results from ePIC, and reduce the combined systematic uncertainties. And in combination with...
