TL;DR
This paper discusses a modified Yamaguchi function for the Bethe-Salpeter equation with a separable kernel, tailored for describing breakup reactions involving interacting nucleon pairs in the final state.
Contribution
It introduces a specific form of the separable function based on the analytic structure of the hadron current for breakup reactions.
Findings
The modified Yamaguchi function effectively models breakup reactions.
The approach aligns with the analytic properties of the hadron current.
It provides a framework for analyzing electro-, photo-, and nucleon-disintegration of the deuteron.
Abstract
In the paper the so-called modified Yamaguchi function for the Bethe-Salpeter equation with a separable kernel is discussed. The type of the functions is defined by the analytic stucture of the hadron current with breakup - the reactions with interacting nucleon-nucleon pair in the final state (electro-, photo-, and nucleon-disintegration of the deuteron).
