Contribution

It highlights the vector meson exchange dominance in short-range light quark interactions, aligning recent findings with earlier hadron spectroscopy models.

Findings

VME dominance observed in $NN$, $D_{03}$, and $D_{30}$ systems

Supports earlier quark model studies with hidden local symmetry

Provides explanation for empiric VME dominance in hadron interactions

Abstract

I give a brief comment on a recent study revealing the vector meson exchange (VME) dominant for the short range interactions between u/d quarks in the $NN$, $D_{03}$, and $D_{30}$ systems. The finding echoes nicely with an earlier study of hadron spectroscopy using a quark model with hidden local symmetry which also favors the VME dominant for the short range interactions of light quarks. The VME dominance for the short range interactions of light quarks gives a natural explanation of the empiric VME dominance for the interactions between hadrons containing light quarks.
