Reimei Workshop "Hadrons in dense matter at J-PARC"

Feb 21, 2022, 9:00 AM → Feb 23, 2022, 10:00 PM Asia/Seoul

Su Houng Lee (Yonsei University), Atsushi Hosaka (RCNP, Osaka University), H. Sako (JAEA), Philipp Gubler (JAEA)

The Reimei Workshop "Hadrons in dense matter at J-PARC" will be held on February 21 - 23, 2022 in hybrid style, with both on-site and online participants. The workshop will focus on topics around the behavior and modifications of hadrons in nuclear matter, their relation to QCD and chiral symmetry, related experimental measurements at facilities around the world and especially the ongoing E16 experiment at J-PARC. The goal of the workshop is to stimulate discussions between theorists and experimentalists in order to exchange new ideas and to provide an overview of the current status of the field.

About the Reimei-workshop Series:
This Reimei Workshop is part of a series of workshops sponsored by the Japan Atomic Energy Agency (JAEA). Reimei means "dawn" in Japanese, and the workshops of this series are intended to highlight the physics being done now, or in the near future, at JAEA and its related facilities, such as J-PARC.

Online connection: 
A zoom-link will be sent to the registered participants a few days before the start of the workshop. 
The talks will be recorded and made accessible for registered participants. Please contact the 
organizers in case you do not wish your talk to be recorded.
