$K_s^0 Hadronization Following DIS at CLAS

TL;DR

This paper investigates how neutral kaons ($K^0$) form from quarks during deep inelastic scattering within nuclear matter, providing insights into the space-time process of hadronization at CLAS.

Contribution

It presents the first measurements of $K^0$ hadronization in SIDIS on various nuclei, comparing results with pions and $K^+$ to deepen understanding of hadron formation.

Findings

Multiplicity ratios indicate nuclear medium effects on $K^0$ production.

$ riangle p_T^2$ values suggest differences in transverse momentum broadening.

Results are consistent with models of quark propagation and hadronization in nuclear matter.

Abstract

The hadronization of $K^0$ particles was measured in semi-inclusive deep inelastic scattering (SIDIS) kinematics for several nuclear targets using the CLAS detector. Multiplicity ratios and $\Delta p_T^2$ values were extracted from the data. These results may be compared with similar values for $\pi^+$ hadronization from CLAS (at the same kinematics) and $K^+$ hadronization from HERMES (at higher energy transfer). The physics goal of these measurements is to understand the space-time evolution as the struck quark becomes a full-blown hadron as it propagates through nuclear matter.
