Hadronization Studies via $\omega(782)$ Electroproduction off D, C, Fe, and Pb

A complete picture of the strong interaction must include hadronization, the dynamical process of a free quark forming a color-neutral hardon. To study the hadronization of the vector meson $\omega(782)$, we perform semi-inclusive deep-inelastic scattering measurements on deuterium, carbon, iron, and lead using data collected with the CLAS detector at Jefferson Lab employing a 5.014 GeV electron beam. To examine nuclear dependence, we present $\omega$ multiplicities of the solid targets relative to those on deuterium as one-dimensional functions of the virtual-photon energy $\nu$, the photon virtuality $Q^2$, the fractional hadron energy $z$, and the square of the hadron transverse momentum $p_T^2$. This analysis corresponds to the first hadronization studies of the $\omega$ meson and hints at a promising future for upcoming CLAS12 and EIC experiments, where more detailed investigations could be achieved.
