This issue, celebrating the 30th Anniversary of the Journal, contains two review articles, one in exotic hadrons and one in antikaon-nucleon systems, as well as a selection of original articles on experimental and theoretical physics in  which modern problems in few-body systems are discussed. Specific arguments, presented by world expert leaders, are very extensive and include the three and four-nucleon system, short-range correlations, universal behavior in few-boson systems, perspectives on the origin of hadron masses, scattering problems and studies using electromagnetic probes. This issue gives an overview of actual problems in Few-Body Systems.The articles have been previously published in Few-Body Systems, Volumes 57 - 58 (2016 - 2017) weiterlesen
