This paper reports world averages of measurements of b-hadron, c-hadron, and τ τ-lepton
properties obtained by the Heavy Flavour Averaging Group using results available through …

Chiral symmetry and its spontaneous breaking play an important role both in the light
hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …

This paper reports world averages of measurements of b-hadron, c-hadron, and τ-lepton
properties obtained by the Heavy Flavor Averaging Group using results available before …

Since the discovery of the first charmed meson in 1976, many open-charm and open-bottom
hadrons were observed. In 2003 two narrow charm-strange states $ D_ {s0}^{\ast}(2317) …

Quantum chromodynamics (QCD), the generally accepted theory for strong interactions,
describes the interactions between quarks and gluons. The strongly interacting particles that …

This paper gives results for the spectrum, all allowed E1 radiative partial widths (and some
important M1 widths) and all open-charm strong decay amplitudes of all 40 cc¯ states …

Glueballs, hybrids and multiquark states are predicted as bound states in models guided by
quantum chromo dynamics (QCD), by QCD sum rules or QCD on a lattice. Estimates for the …

This article reports world averages of measurements of $ b $-hadron, $ c $-hadron, and
$\tau $-lepton properties obtained by the Heavy Flavor Averaging Group (HFAG) using …

The masses of the ground, orbitally and radially excited states of heavy-light mesons are
calculated within the framework of the QCD-motivated relativistic quark model based on the …
