Cross sections of inclusive $\psi(2S)$ and $X(3872)$ production from $b$-hadron decays in $pp$ collisions and comparison with ATLAS and CMS data

TL;DR

This paper analyzes the production cross sections of $ ext{psi}(2S)$ and $X(3872)$ particles from $b$-hadron decays in proton-proton collisions at the LHC, comparing theoretical predictions with experimental data from ATLAS, CMS, and LHCb.

Contribution

It provides a detailed comparison of theoretical cross section calculations with experimental measurements for $ ext{psi}(2S)$ and $X(3872)$ production at different energies.

Findings

Good agreement between theory and experiment for $ ext{psi}(2S)$ production.

Discrepancies observed in $X(3872)$ production cross sections.

Energy dependence of production cross sections analyzed.

Abstract

We study the cross sections for the inclusive production of $\psi(2S)$ and $X(3872)$ hadrons in $pp$ collisions at the LHC at two different center-of-mass energies and compare with experimental data obtained by the ATLAS, CMS, and LHCb collaborations.
