# Elastic pp scattering and the internal structure of colliding proton

## TL;DR

This paper analyzes high-energy elastic proton-proton scattering data to interpret the internal structure of protons, suggesting that elastic processes are better viewed as peripheral and related to the superposition of two internal structures with specific dimensions.

## Contribution

It demonstrates that elastic pp scattering at 53 GeV can be interpreted as collisions between two internal structures with measurable external dimensions, providing a new perspective on proton internal structure.

## Key findings

- Elastic pp data at 53 GeV can be modeled as superpositions of internal structures.
- The approximate dimensions of these structures are estimated from the data.
- Elastic scattering is better interpreted as a peripheral process rather than central.

## Abstract

Elastic scattering data gained for proton-proton collisions at high energies are being analyzed at the present practically only with the help of purely phenomenological mathematical models. And the question exists whether in the impact parameter plane the elastic processes may be interpreted as central or peripheral. From realistic point of view the peripherality should be preferred and one may expect that nucleon dimensions should manifest in some way in elastic data. It will be demonstrated that the elastic pp data at the energy of 53 GeV in the interval |t| from (0., 4.) [GeV^2] may be interpreted well as the superposition of mutual collisions of two internal structures with maximal external dimensions; the approximate dimensions and frequencies of corresponding structures being established on the basis of measured elastic data.
