On the XIIIth international workshop on low-energy e(+) and Ps physics

A comment is presented on the XIIIth International Workshop on Low-Energy Positron and Positronium Physics (held at UNICAMP, Campinas, Brazil, 27- 30 July 2005). Exciting progress was reported on a range of antimatter research areas. The focus of the conference is on understanding fundamental positron and positronium scattering and annihilation from gas-phase atoms and molecules. Other hot topics included antihydrogen production and antimatter- and matter-bound states. We discuss some of the achievements and outstanding questions that have arisen during the past two years and discuss some directions for the future
