California EIC Consortium Collaboration Meeting 2024
Glen Mor Meeting Room
University of California, Riverside
We are happy to announce that the California EIC Consortium Collaboration Meeting will be held at the University of California, Riverside on February 29-March 1, 2024. It will commence at 9 AM on Thursday and conclude at 12:00 PM on Friday.
This is a great opportunity for researchers, scientists, and students in the field of Electron-Ion Collider (EIC) to come together and share their latest findings, as well as collaborate on new projects. We hope to see you there!
Meeting room: The meeting will be held in the "Glen Mor Meeting Room K106/K108". To get there, please see the directions tab.

Proton-going ECal design and simulations
The proton-going Electromagnetic Calorimeter (pECal), situated in the Hadron Endcap alongside the forward Hadronic Calorimeter in the ePIC detector configuration, plays a crucial role in the ePIC scientific program for jet and photon/electron measurements. With an inner radius of 30 cm and an outer radius of 170 cm, the pECal spans a pseudorapidity range from 1.4 to 3.5.
The pECal's primary function is to facilitate the identification of $\pi^0$ decay photons up to 50 GeV and the reconstruction of jets with good hadron compensation in the hadron-going direction. Utilizing a sampling calorimeter design with a W-powder/ScFiber (W/ScFi) structure, initially developed at UCLA, this compact configuration efficiently fits within limited space constraints. Notably, the pECal boasts good energy resolution and fine granularity, meeting the stringent requirements of the ePIC scientific program.
During this presentation, I will show the pECal design and discuss the capabilities of the fECal in differentiating $\pi^0$ decay photons and identifying heavy-flavor jets from current simulations and machine-learning techniques.

Update on u-channel EIC Analyses
Backward ($u$-channel) meson production and DVCS results in baryons undergoing large momentum transfers. These reactions are interesting for their potential to provide insight on the mechanisms behind baryon stopping, and the nature of the baryon number inside the proton. We report an update on various $u$-channel physics simulations for the EIC, including a short summary report on our backward DVCS paper, and the status of several physics benchmarks in preparation for the ePIC TDR.

Transverse energy-energy correlators in the Color-Glass Condensate
Transverse energy-energy correlators (TEECs) are event-shape observables that can be used to study QCD by examining angular correlations between produced particles. As they are weighted by the energy of the particle, they are an infrared-safe observable that can be calculated to high accuracy. This makes TEECs a potentially useful tool in extracting the target structure in DIS and studying physics in the small-$x$ regime where saturation effects are believed to be important.
In this talk, we will present results for TEECs in back-to-back electron-hadron production in the small-$x$ region of DIS [1]. We establish a factorization theorem given in terms of the hard function, soft function, TEEC jet function, and quark distribution. The quark distribution is written in terms of the small-$x$ dipole amplitudes which incorporate the saturation effects. By considering both proton and nuclear targets in DIS, we demonstrate that TEECs can be a powerful tool to understand gluon saturation and nuclear modification at the upcoming Electron-Ion Collider.
