Simulation of meson–proton interactions is considered in the framework of a new phenomenological model (FANSY 2.0 QGSJ) developed on the basis of the traditional quark-gluon string model to simulate hadron interactions in a wide energy range. The m

We investigate the contributions of sea quarks and gluon to the structure of pion and kaon at low Q2 scale. To this end, we calculate the sea quark and gluon distribution functions of these mesons applying the modified chiral quark model ( $ \chi QM$

The couplings of unflavored vector mesons to the $e^+e^-$ annihilation are an important source of information on the nature and structure of these resonances which play a prominent role in the hadron phenomenology. The couplings of many radially exci

The magnetic moments, transition magnetic moments and the radiative decay widths of singly charmed baryons are calculated with $ {J^P = \frac{1}{2}}^+$ and $ {J^P = \frac{3}{2}}^+$ in the constitute quark model. Further, the strong decay rates for $

The intranuclear cascade model INCL (Li\`ege Intranuclear Cascade) is now able to simulate spallation reactions induced by projectiles with energies up to roughly 15 GeV. This was made possible thanks to the implementation of multipion emission in th

We have studied the decay constants of the pseudoscalar and the vector B and D mesons in the framework of the light-cone quark model. We have applied a variational method to the relativistic Hamiltonian with the Gaussian-type trial wave function to o

The nature of the $\Lambda (1405)$ has been a puzzle for decades, whether it is a standard three-quark baryon, a hybrid baryon or a baryon-meson molecule. More information on the decay channels of this particle and its strong, weak and electromagneti

The parameters, i.e. the mass and current coupling of the exotic $X(5568)$ state observed by the D0 Collaboration as well as the decay width of the process $X \to B_s^{0}\pi^{+}$ are explored using $B\bar{K}$ molecule assumption on its structure. Emp

A survey of basic properties of the decay of unstable nuclei is here presented, with a focus on \( \alpha\) and \( \beta\) decay. An overview of basic properties and the description of few examples of recently measured decays in exotic nuclei are giv

Using the DGLAP evolution equation with the corrections of parton recombinations, the flavor asymmetric sea quark distributions in the proton are first extracted from the available experimental data with the global QCD analysis method. Comparisons of
