Overview
Prof. Roxanne Springer works on weak interactions (the force responsible for nuclear beta decay) and quantum chromodynamics (QCD, the force that binds quarks into hadrons). The weak interactions are an excellent place to look for fundamental symmetry violations which may occur in nature, while the study of QCD is necessary for understanding protons, neutrons, and their partner particles. Dr. Springer uses effective theories involving these forces to study processes in both nuclear and particle physics.

The role of intermediate ΔΔ states in nucleon-nucleon scattering in the large-Nc and unitary limits, and ΔΔ and ΩΩ scattering
Journal Article Journal of Physics G Nuclear and Particle Physics · August 31, 2025 We explore potential explanations for why using large-Nc (Nc is the number of colors) scaling to determine the relative size of few-nucleon low-energy operators agrees with experiment even when dynamical Δ’s are not explicitly include ...

Journal Article Physical Review C · October 1, 2023 We calculate the cold neutron-deuteron (nd) capture cross section,σnd to next-to-next-to leading order (NNLO) using the model-independent approach of pionless effective-field theory [EFT(π)]. At leading order we find σnd=0.314±0.217 mb, while the experimen ... Full text CiteImplications of Large-N QCD for the NN Interaction
Journal Article Annual Review of Nuclear and Particle Science · September 25, 2023 We present a method for ordering two-nucleon interactions based upon their scaling with the number of QCD colors, Nc, in the limit that Nc becomes large. Available data in the two-nucleon sector show general agreement with this orderi ... Full text CiteRecent Grants
