O.V. Selyugin, and J.-R. Cudell
TL;DR
This paper investigates the impact-parameter representation of the hadron elastic scattering spin-flip amplitude across various unitarisation schemes, emphasizing the importance of the asymptotic amplitude value over the specific unitarisation method.
Contribution
It demonstrates that unitarisation scheme properties are unaffected by the functional form but are significantly influenced by the asymptotic value of the unitarised amplitude.
Findings
Properties of unitarisation schemes are independent of the functional form.
The asymptotic value of the unitarised amplitude critically affects scheme properties.
The Born term from the Dubna Dynamical Model is used for the spin-flip amplitude.
Abstract
The impact-parameter representation of the spin-flip amplitude of hadron elastic scattering is examined in different unitarisation schemes, taking the Born term of the spin-flip amplitude from the Dubna Dynamical Model (DDM). It is shown that the basic properties of the unitarisation schemes are independent of the functional form used for unitarisation but heavily depend on the asymptotic value of the unitarised amplitude.
