Kent+OSU Nuclear Experiment Joint Meeting May 2024

On May 20 - 24, we held a joint meeting of the Kent and OSU nuclear experimental groups. Since I and Zhangbu both started at our respective positions recently, we wanted to introduce our groups and cover a broad range of material beneficial for new students. The agenda allowed ample time for discussion and questions from everyone. We had the meeting at Kent State University on Monday - Wednesday. On Wednesday afternoon we took a group excursion to the Cuyahoga Falls National Park (see pictures below). On Thursday - Friday we hosted the meeting at OSU. We had about 20 people in attendance each day including undergraduates, pre- and post- candidacy students, post-docs and faculty from both universities. We had 21 talks on various topics in high-energy heavy ion physics.

On the final day we used this opportunity to also pilot another idea - to unify nearby institutions contributioning to the electron ion-collider and the ePIC experiment. On Friday we hosted the first ePIC Midwest meeting to discuss the ongoing efforts at Kent and OSU. Our agenda focuses on three topics according to the recent leadership positions taken by each institutions: 1) Zhangbu is the detector subsystem leader for the AC-LGAD TOF detector, 2) Leszek is the detector subsystem leader for the backward HCAL, and 3) I recently led the implementation of the initial electron-finder into the official EICRecon framework.

The meeting was a great success on several fronts. Scientifically, it provided a friendly and welcoming environment for new students to gain foundational knowledge about the field. Eight of the twenty participants were pre-candidacy or undergraduate students, and seven members gave their first presentation (outside of local group meetings). We also opened the ePIC Midwest session over ZOOM to welcomed University of Illinois Urbana-Champaign to the backward HCAL effort.
