  Liquid argon technology is widely used by many previous and current neutrino
experiments, and it is also promising for future large-scale neutrino
experiments. When detecting neutrinos using liquid argon, many hadrons are
involved, which can also interact with argon nuclei. In order to gain a better
understanding of the detection processes, and to simulate neutrino events,
knowledge of hadron-argon cross sections is needed. This paper describes a new
procedure which improves upon the previous work with multi-dimensional
unfolding to measure hadron-argon cross sections in a liquid argon time
projection chamber. Through a simplified version of simulation, we demonstrate
the validity of this procedure.
