Tetraquarks and pentaquarks from quark model perspective

H Huang, C Deng, X Liu, Y Tan, J Ping - Symmetry, 2023 - mdpi.com
According to the classification of the quark model, the hadrons going beyond three-quark
baryon and quark-antiquark meson pictures are called exotic hadrons. Many new hadrons …

QCD and the strange baryon spectrum

T Hyodo, M Niiyama - Progress in Particle and Nuclear Physics, 2021 - Elsevier
The strange quark plays a unique role in QCD, reflecting its intermediate mass between the
light and heavy quarks. In recent years, remarkable progress has been made in the …

Heavy baryons in a quark model

W Roberts, M Pervin - International Journal of Modern Physics A, 2008 - World Scientific
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 …

B Chen, KW Wei, X Liu, T Matsuki - The European Physical Journal C, 2017 - Springer
In this work, we systematically study the mass spectra and strong decays of 1 P and 2 S
charmed and charmed-strange baryons in the framework of non-relativistic constituent quark …

Observation of an Excited Baryon

J Yelton, I Adachi, JK Ahn, H Aihara, S Al Said… - Physical review …, 2018 - APS
Using data recorded with the Belle detector, we observe a new excited hyperon, an Ω*-
candidate decaying into Ξ 0 K-and Ξ-KS 0 with a mass of 2012.4±0.7 (stat)±0.6 (syst) MeV/c …

Spectroscopic investigation of light strange S=− 1 Λ and Σ and S=− 2 Ξ baryons

C Menapara, AK Rai - Chinese Physics C, 2021 - iopscience.iop.org
The present study is dedicated to light-strange with strangeness S=− 1 and isospin I= 0, with
S=− 1 and I= 1, and baryon with S=− 2 and. In this study, the hypercentral constituent quark …

Spectroscopic study of strangeness=–3 Ω–baryon

C Menapara, AK Rai - Chinese Physics C, 2022 - iopscience.iop.org
Ω− Abstract: baryon with sss quarks has been investigated through many theoretical studies
so far but scarcely observed in experiments. Here, an attempt has been made to explore …

[HTML][HTML] Quantum number assignments of light strange baryons in Regge phenomenology

J Oudichhya, K Gandhi, AK Rai - Nuclear Physics A, 2023 - Elsevier
The present article contains the descriptive study of light strange baryons Λ, Σ, Ξ, and Ω. The
Regge phenomenology with quasi-linear Regge trajectories has been employed and the …

Observation of and Evidence for in Decays

M Sumihama, I Adachi, JK Ahn, H Aihara, S Al Said… - Physical review …, 2019 - APS
We report the first observation of the double strange baryon Ξ (1620) 0 in its decay to Ξ-π+
via Ξ c+→ Ξ-π+ π+ decays based on a 980 fb-1 data sample collected with the Belle …

baryon spectrum and their decays in a constituent quark model

MS Liu, KL Wang, QF Lü, XH Zhong - Physical Review D, 2020 - APS
Combining the recent developments of the observations of Ω sates we calculate the Ω
spectrum up to the N= 2 shell within a nonrelativistic constituent quark potential model …
