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 …

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) …

The Ξ c+ K-mass spectrum is studied with a sample of pp collision data corresponding to an
integrated luminosity of 3.3 fb-1, collected by the LHCb experiment. The Ξ c+ is …

Mass spectra of heavy baryons are calculated in the heavy-quark–light-diquark picture in the
framework of the QCD-motivated relativistic quark model. The dynamics of light quarks in the …

A quark model is applied to the spectrum of baryons containing heavy quarks. The model
gives masses for the known heavy baryons that are in agreement with experiment, but for …

About 120 baryons and baryon resonances are known, from the abundant nucleon with u
and d light-quark constituents up to the Ξ b−=(bsd), which contains one quark of each …

The composite nature of baryons manifests itself in the existence of a rich spectrum of
excited states, in particular in the important mass region 1–2 GeV for the light-flavoured …

The strong and radiative decays of the low-lying S-and P-wave Λ c (b), Σ c (b), Ξ c (b), Ξ c
(b)′, and Ω c (b) baryons are systematically studied in a constituent quark model. We find …

From samples of pp collision data collected by the LHCb experiment at s= 7, 8 and 13 TeV,
corresponding to integrated luminosities of 1.0, 2.0 and 1.5 fb-1, respectively, a peak in both …

The mass spectra of the excited heavy baryons consisting of two light (u, d, s) and one heavy
(c, b) quarks are calculated in the heavy-quark–light-diquark approximation within the …
