Understanding the structure of d*(2380) in chiral quark model [PDF]
Science China Physics Mechanics and Astronomy, 2015 The structure and decay properties of d* have been detailedly investigated in both the chiral SU(3) quark model and the extended chiral SU(3) quark model that describe the energies of baryon ground states and the nucleon-nucleon (NN) scattering data ...

Properties of color-flavor locked matter in a quasiparticle model
European Physical Journal C: Particles and Fields, 2023 We investigate the thermodynamical properties of color-flavor locked (CFL) quark matter at zero temperature, finite temperature, and strong magnetic field by using quasiparticle model. We find that considering CFL quark phase can significantly change the

Hyperon Polarization in a Quark-Quark Scattering Model [PDF]
AIP Conference Proceedings, 2007 A continuing mystery in particle physics is the large polarization observed in inclusive hyperon production in high energy p-p collisions. In this paper the authors advance the concept that the polarization effects can be accounted for in a simple model based on quarks becoming polarized in the direct q-q scattering process and where, at a fundamental ...

Strange baryon spectroscopy in the relativistic quark model [PDF]
, 2015 Mass spectra of strange baryons are calculated in the framework of the relativistic quark model based on the quasipotential approach. Baryons are treated as the relativistic quark-diquark bound systems.

New signals for vector-like down-type quark in U(1) of $$E_6$$ E6
European Physical Journal C: Particles and Fields, 2018 We consider the pair production of vector-like down-type quarks in an $$E_6$$ E6 motivated model, where each of the produced down-type vector-like quark decays into an ordinary Standard Model light quark and a singlet scalar.

Dibaryons in a constituent quark model [PDF]
, 2015 We investigate the properties of dibaryons containing u and d quarks in the constituent quark model. In constructing the ground state wave function, we choose the spatial part to be fully symmetric and the remaining color, isospin and spin part to be ...

Asymmetries of quark sea in nucleon
EPJ Web of Conferences, 2014 The effects of “quark sea” in determining the flavor structure of the octet baryons have been investigated in the chiral constituent quark model. The chiral constituent quark model is able to qualitatively generate the requisite amount of quark sea and ...

The structure of pentaquarks $P_c^+$ in the chiral quark model [PDF]
, 2015 The recent experimental results of LHCb collaboration suggested the existence of pentaquark states with charmonium. To understand the structure of the states, a dynamical calculation of 5-quark systems with quantum numbers $IJ^P=\frac{1}{2}(\frac{1}{2})^\

The Effective Baryon–Baryon Potential with Configuration Mixing in Quark Models
UniverseThe effective baryon–baryon potential can be derived in the framework of the quark model. The configurations with different quark spatial distributions are mixed naturally when two baryons get close. The effect of configuration mixing in the chiral quark
