Exotic Hadrons in Vacuum & Matter


The Workshop "Exotic Hadrons in Vacuum & Matter" is held on March 2, 2023 at the Advanced Science Research Center (Room 205), JAEA, Tokai-mura, Japan. The goal of the workshop is to stimulate discussions between theorists and experimentalists in order to exchange new ideas in a relaxed atmosphere.

The workshop will focus on topics the following topics: 

-Exotic hadrons and their structure 
-Experimental methods to study exotic hadrons 
-Behavior of vector mesons in nuclear matter 
-E16 J-PARC experiment
-Related topics
