Contribution

It offers a detailed analysis of the impact of RG evolution on nuclear structure and reaction components in a controlled two-body system.

Findings

RG transformations leave cross sections invariant

Wave functions and interaction currents are significantly altered

Dependence of modifications on kinematic conditions

Abstract

Renormalization group (RG) methods used to soften Hamiltonians for nuclear many-body calculations change the effective resolution of the interaction. For nucleon knock-out processes, these RG transformations leave cross sections invariant, but initial-state wave functions, interaction currents, and final-state interactions are individually altered. This has implications for the factorization of nuclear structure and reactions. We use deuteron electrodisintegration as a controlled laboratory for studying how structure and reaction components are modified under RG evolution, without the complication of three-body forces or currents. The dependence of these changes on kinematics is explored.
