Self-consistent description of HERA data at low $Q^2$ and soft hadron production at LHC

TL;DR

This paper presents a unified theoretical framework that accurately describes low $Q^2$ proton structure data from HERA and soft hadron production at LHC using a self-consistent gluon density model within the color dipole and quark-gluon string frameworks.

Contribution

It introduces a self-consistent analytical gluon density model that simultaneously explains diverse phenomena across different energy scales and experiments.

Findings

Successful description of $F_2(x,Q^2)$ data at low $Q^2$ from HERA

Accurate modeling of soft hadron production at LHC

Unified approach linking proton structure and hadron production

Abstract

Using the analytical expression for transverse momentum dependent (TMD) gluon density in a proton, a self-consistent simultaneous description of low $Q^2$ data on proton structure function $F_2(x,Q^2)$, reduced cross section for the electron-proton deep inelastic scattering at HERA and soft hadron production in $pp$ collisions at the LHC is achieved in the framework of color dipole approach and modified quark-gluon string model.
