Charged-particle multiplicity dependence of charm-baryon-to-meson ratio in high-energy proton-proton collisions

open access: yesPhysics Letters B, 2021
We propose that the charged-particle multiplicity dependence of the charm-baryon-to-meson ratio observed in high-energy pp collisions can be explained by canonical treatment of quantum charges in the statistical hadronization model (SHM). Taking the full

Simple Scenario of Photons Emission from Anti Charm–Gluon Interaction using QCD Theory

open access: yesJournal of Kufa-Physics, 2023
  In this work, the chromodynamics (QCD) theory was used to investigate the photon rate which was produced in interactions of anti-charm with gluon.

Ξc−Ξc′ mixing from lattice QCD

open access: yesPhysics Letters B, 2023
In heavy quark limit, the lowest-lying charmed baryons with two light quarks can form an SU(3) triplet and sextet. The Ξc in the SU(3) triplet and Ξc′ in the sextet have the same JPC quantum number and can mix due to the finite charm quark mass and the ...

The melting and abundance of open charm hadrons

open access: yesPhysics Letters B, 2014
Ratios of cumulants of conserved net charge fluctuations are sensitive to the degrees of freedom that are carriers of the corresponding quantum numbers in different phases of strong interaction matter.

Thermal dileptons production from the QGP in the intermediate mass region [PDF]

open access: yesAIP Advances
A momentum distribution function incorporating quark number density and temperature was constructed. Based on the reaction mechanism of quantum chromodynamics and the Bjorken hydrodynamic model, the production expression of thermal dileptons from the ...

The 3-loop non-singlet heavy flavor contributions and anomalous dimensions for the structure function F2(x,Q2) and transversity

open access: yesNuclear Physics B, 2014
We calculate the massive flavor non-singlet Wilson coefficient for the heavy flavor contributions to the structure function F2(x,Q2) in the asymptotic region Q2≫m2 and the associated operator matrix element Aqq,Q(3),NS(N) to 3-loop order in Quantum ...

Interpretation of the narrow J/ψ p peaks in Λb → J/ψ p K− decay in the compact diquark model

open access: yesPhysics Letters B, 2019
Recently, the LHCb Collaboration have updated their analysis of the resonant J/ψp mass spectrum in the decay Λb0→J/ψpK−. In the combined Run 1 and Run 2 LHCb data, three peaks are observed, with the former Pc(4450)+ state split into two narrow states, Pc(

Elucidating the nature of hidden-charm pentaquark states with spin-32 through their electromagnetic form factors

open access: yesPhysics Letters B
We perform a systematic study of the electromagnetic properties of exotic states to shed light on their nature, which is still controversial and not fully understood. The magnetic dipole and higher multipole moments of a hadronic state are as fundamental

Application of fragmentation function to the indirect production of fully charmed tetraquark

open access: yesEuropean Physical Journal C: Particles and Fields
The indirect production mechanisms of fully charmed tetraquark are analyzed using the NRQCD factorization and Suzuki approach, respectively. The process first produces a heavy charm quark through Higgs, $$W^+$$ W + , or $$Z^0$$ Z 0 decay, and then the ...

Heavy mesons mass spectroscopy under a spin-dependent Cornell potential within the framework of the spinless Salpeter equation

open access: yesOpen Physics
The energy bound-state solutions of the spinless Salpeter equation (SSE) have been obtained under a spin-dependent Cornell potential function via the Wentzel–Kramers–Brillouin approximation.
