In most theoretical approaches to hadron resonances these states have been described as excited bound states rather than as genuine resonances taking into account their decay channels explicitly. As a result essential properties, such as the decay widths, have not been predicted strictly from quantum chromodynamics (QCD). Most of the existing results must therefore be considered as stemming...
Properties and applications of QED parton distribution and fragmentation functions are discussed. Optimization of the factorization scale choice is demonstrated for specific processes. A new factorization scheme is proposed for Drell-Yan processes in QED. Features of QED and QCD parton distribution functions are compared.
Within Yang-Mills-Proca theory with external sources, finite-energy regular solutions have been obtained. It is shown that color electric/magnetic fields have two components: the first one is a gradient/curl component, respectively, and the second one is a nonlinear component. It is shown that the color electric field has $\Upsilon-$like spatial distribution. In this case, the $\Upsilon-$like...
The heavy baryon spectroscopy is crucial for gaining deeper insights into the strong interaction in the Quantum Chromodynamics (QCD). It has attracted considerable experimental and theoretical attentions. So far, a large number of singly heavy baryons have been observed in experiment, which provides the important support for related theoretical researches. The mass spectroscopy of Σc will be...
We consider a vacuum wavefunctional for SU(N) Yang-Mills theory peaked at thick center vortices. The vacuum average of the 't Hooft within this wavefunctional yields a perimeter law, while that of the Wilson loop yields an area law,, consistent with both criterions for confinement. In this work, we evaluate the topological susceptibility of the vacuum in this framework, and use the results to...
Hadrons, including mesons and baryons, constitute the smallest observable units with internal structure that can be separated from matter. The search for new hadronic states and the exploration of the internal quark-gluon structure of hadrons represent a shared frontier research topic in both particle physics and medium-to-high energy nuclear physics. In recent years, an increasing number of...
