Multi-Nucleon Short-Range Correlation Model for Nuclear Spectral Functions: I. Theoretical Framework

Understand

We develop a theoretical approach for nuclear spectral functions at high missing momenta and removal energies based on the multi-nucleon short-range correlation~(SRC) model.

• The approach is based on the effective Feynman diagrammatic method which allows to account for the relativistic effects important in the SRC domain.
• In addition to two-nucleon SRC with center of mass motion we derive also the contribution of three-nucleon SRCs to the nuclear spectral functions.
• The latter is modeled based on the assumption that 3N SRCs are a product of two sequential short range NN interactions.
