Interactions between hard partons and the quark-gluon plasma range from frequent soft interactions to rare hard interactions. While it is reasonable that hard interactions can be described perturbatively, soft interactions likely have significant non-perturbative effects. The cumulative effect of the soft interactions can be encoded into parton transport coefficients, which can be constrained from heavy ion measurements. In this work, we perform a simplified proof of principle calculations showing that the magnitude of the drag and diffusion of light partons can be constrained from the hadronic and jet RAA, assuming a known temperature dependence of the soft transport coefficients. We show how this study can be implemented naturally in a parton energy loss model that factorizes systematically soft and hard partonic interactions. We use this proof of principle calculation to understand how reducing uncertainties on RAA can improve constraints on the parton's transport coefficients. We also observe the complementarity of jet and hadronic observables to constrain the light parton transport coefficients.
