# Rapidity dependent transverse momentum spectra of heavy quarkonia produced in small collision systems at the LHC

## TL;DR

This paper models the rapidity-dependent transverse momentum spectra of heavy quarkonia in small collision systems at the LHC using a two-component statistical approach, successfully fitting experimental data and analyzing parameter dependencies.

## Contribution

It introduces a two-component statistical model based on Tsallis statistics and inverse power-law to describe heavy quarkonia spectra in small collision systems at the LHC.

## Key findings

- Model fits well to LHCb data across rapidities.
- Parameters show specific dependence on rapidity.
- Provides insights into particle production mechanisms.

## Abstract

The rapidity dependent transverse momentum spectra of heavy quarkonia (J/psi and Upsilon mesons) produced in small collision systems such as proton-proton (pp) and proton-lead (p-Pb) collisions at center-of-mass energy (per nucleon pair) 5-13 TeV are described by a two-component statistical model which is based on the Tsallis statistics and inverse power-law. The experimental data measured by the LHCb Collaboration at the Large Hadron Collider (LHC) are well fitted by the model results. The related parameters are obtained and the dependences of parameters on rapidity are analyzed.
