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

EPJ Web of Conferences, 2015 In this contribution, we briefly discuss the results for charmonium and bottomonium spectra with self-energy corrections in the unquenched quark model, due to the coupling to the meson-meson continuum The UQM formalism can be extended to include also the

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

Evidence for quark-matter cores in massive neutron stars [PDF]
Nature Physics, 2019 The theory governing the strong nuclear force—quantum chromodynamics—predicts that at sufficiently high energy densities, hadronic nuclear matter undergoes a deconfinement transition to a new phase of quarks and gluons1.

Chemistry – A European Journal, EarlyView.Five heteroleptic iridium(III) complexes bearing cyclometalated 2,4‐diphenylpyridinato ligands were synthesized and their electrochemiluminescence (ECL) investigated. Two different coreactants were evaluated: tri‐n‐propylamine and benzoyl peroxide under anodic and cathodic potentials, respectively.

High-energy dileptons from an anisotropic quark-gluon plasma [PDF]
, 2009 We calculate leading-order dilepton yields from a quark-gluon plasma which has a time-dependent anisotropy in momentum space. Such anisotropies can arise during the earliest stages of quark-gluon plasma evolution due to the rapid longitudinal expansion ...

Search for Possible Stable Structures in the
AtomsInspired by the well-known experimental connections between X(3872), Zcs(4220), and Y(4620), we systematically study the recently reported strange partner of Tcc, the 1+ccq¯s¯ system, and its orbital excitation state 1−ccq¯s¯.

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 ...

Understanding the charmed states recently observed by the LHCb and BABAR Collaborations in the quark model [PDF]
, 2014 Comparing the expected spectroscopy in the relativistic quark model and the predicted strong decays in the $^3P_0$ model employing the realistic wave functions from the relativistic quark model with the measured properties of the LHCb and BaBar charmed ...

Generalized Beth–Uhlenbeck Entropy Formula From the Φ‐Derivable Approach
Contributions to Plasma Physics, EarlyView.ABSTRACT We derive a generalized Beth–Uhlenbeck formula for the entropy of a dense fermion system with strong two‐particle correlations, including scattering states and bound states. We work within the Φ‐derivable approach to the thermodynamic potential.
