# Rapidity Distributions of Hadrons in Proton-Nucleus Collisions

## TL;DR

This paper introduces a new model for proton-lead collisions that links the proton's Fock states to rapidity distributions, successfully comparing with existing data and exploring high multiplicity scenarios.

## Contribution

The paper presents a novel model connecting proton Fock states to rapidity distributions in proton-nucleus collisions, incorporating maximum entropy distributions and energy shifts.

## Key findings

- Model matches existing 5 TeV data.
- Predictions for 8 TeV collisions.
- Insights into high multiplicity events.

## Abstract

We study proton-lead collisions with a new model for the Fock states of the incoming proton. The number of collisions which the proton experiences selects the appropriate Fock state of the proton which generates a multiple of pp-like rapidity distributions. We take as input the pp maximum entropy distributions shifting the respective cm-rapidities and reducing the available energies. A comparison with existing data at 5 TeV is made and results for 8 TeV are presented. We also explore the high multiplicity data in this model.
