This meeting follows the successful previous workshop held at the Nagoya University in September 2013, 2015 and 2017. This is a joint workshop of the LHC forward physics working group meeting and the High-Energy Scattering at Zero degrees workshop (HESZ). This year, it aims at covering all aspects of forward physics at the LHC, RHIC, and the incoming EIC at BNL, benefiting from the experience gained at HERA and the Tevatron. The spirit of this meeting is to favour fruitful and informal discussions between experimentalists and theorists. Lots of time is devoted to discussion of new results, hot
