In a previous paper, based on a calculation in the nonrelativistic quark model, we advanced the hypothesis that the D s ð2317Þ, D 0 ð2308Þ mesons are predominantly four-quark states lowered in mass by the flavor-dependent Kobayashi-Kubo-Maskawa 't Hooft U A ð1Þ symmetry breaking effective interaction. Here we show similar results and conclusions in a relativistic effective chiral model calculation, based on three-light-quark (i.e., two q plus one " q) local interpolators. To this end we classify the four-quark (three light plus one heavy quark) local interpolators according to their chiral transformation properties and then construct chiral invariant interactions. We evaluate the diagonal matrix elements of the Kobayashi-Kubo-Maskawa 't Hooft interaction between different interpolating fields and show that the lowest-lying one is always the (antisymmetric) SUð3Þ F antitriplet belonging to the chiral (3, 3) multiplet. We predict bottomstrange B s0 and the bottom-nonstrange B 0 scalar mesons with equal masses at 5720 MeV, the strange meson being some 100 MeV lower than in most of the quark potential models. We also predict the J P ¼ 1 þ bottom-nonstrange B 1 and the bottom-strange B s1 meson masses as 5732 MeV and 5765 MeV, respectively, using the Bardeen-Hill-Nowak-Rho-Zahed scalar-vector mass relation.

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 Λ 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.

This chapter of the report of the "Flavour in the era of the LHC" Workshop discusses the theoretical, phenomenological and experimental issues related to flavour phenomena in the charged lepton sector and in flavour-conserving CP-violating processes. We review the current experimental limits and the main theoretical models for the flavour structure of fundamental particles. We analyze the phenomenological consequences of the available data, setting constraints on explicit models beyond the Standard Model, presenting benchmarks for the discovery potential of forthcoming measurements both at the LHC and at low energy, and exploring options for possible future experiments.
