Il Nuovo Cimento Vol. 45 N. 3 (2022)

This issue of Il Nuovo Cimento is dedicated to the fourth edition of "IWM-EC", the International Workshop on Multi facets of EoS and Clustering, held in November 2021 at GANIL, Caen, France. The meeting, organized every two years alternately in France and Italy, follows a long tradition of conferences organized by CHIMERA and INDRA Collaborations in the past years and focuses on the more recent experimental and theoretical achievements in the field of heavy ions physics, related to fragmentation and clustering phenomena. A large variety of traditional topics together with some new subjects were thus explored thanks to a rich scientific program, keeping connection and continuity with the previous editions and at the same time following the current and future interests in the field.
