The BSW Impact Picture 30 Years After

TL;DR

This paper reviews the 30-year development of the BSW impact picture model for proton-proton and antiproton-proton elastic scattering, emphasizing its evolution and future experimental tests at the LHC.

Contribution

It provides a comprehensive review of the BSW impact picture model's history and discusses how upcoming LHC experiments will test its predictions.

Findings

BSW model successfully described elastic scattering 30 years ago

Evolution of the impact picture over the years

Future LHC experiments will critically test the model's predictions

Abstract

Thirty years ago Bourrely-Soffer-Wu (BSW) investigated an impact picture description of $p-p$ and $\bar p -p$ elastic scattering with success. For this anniversary, a short review of the main features of this picture will be presented with its evolution over the years. The future experiments at the LHC collider will provide decisive tests for the impact picture at high energy.
