Open charm hadron spectroscopy at B-factories

Open charm hadrons are excellent probes to study the dynamics of quarks and gluons inside hadrons. Because the mass of a charm quark is heavier than Lambda(QCD), so called heavy quark symmetry emerges in the hadron containing a charm quark and plays a central role in the classification and constraining the interactions. Belle and BaBar, which are B-factory experiments, have made significant advances in the field of open charm hadron spectroscopy in these 15 years. In this article, experimental advances on both open charm mesons and baryons by B-factory experiments are reviewed. Finally, the prospect of the open charm hadrons with the next generation B-factory experiment, Belle II is described. (C) 2019 Elsevier B.V. All rights reserved.
