In February 2021, the CMS collaboration has reported the observation of X(3872) with anomalously large production yield in Pb-Pb heavy ion collision at 5.02 TeV. Such a large production rate was anticipated by the ExHIC (Exotics from Heavy Ion Collision)  theory collaboration, formed by the present organizers, in a PRL paper, which showed that the large hadron production yields in heavy ion collision could be used to discriminate a molecular from a compact configuration for an exotic hadron.  The work was an outcome of the discussion in the ExHIC inauguration workshop held in 2011 at Yukawa Institute, Kyoto. Furthermore, in July 2021, the LHCb collaboration has observed a doubly charmed meson Tcc, which has been extensively discussed in the 2007 APCTP program on “Hadron Physics at RHIC” organized by the present PI and collaborators with subsequent pioneering publications on the exotic hadron.  

Therefore, in the proposed focus program, the original authors of the pioneering works aim at bringing together experimentalists and theorists on the subject to discuss the current status of the newly developing subject and to probe future research direction.  We will also asses the possibilities of measuring Tcc for the first time from a heavy ion collision and what other measurements for the X(3872) and other hadron physics related observables would be feasible and useful. This will be a continuation of the 2007 APCTP focus program on “Hadron Physics at RHIC” and the extension of the ExHIC collaboration formed in the “Exotics in heavy ion collision (ExHIC)” workshops at YITP in 2011 and “Exotic Phenomena in heavy ion collision (ExHIC-p)” in 2019.

This meeting will be held in the hybrid mode.
