Production of quarkonia and doubly heavy baryons in $pp$-collisions with duality approach

TL;DR

This paper presents a duality-based approach to model the production of heavy quarkonia and doubly heavy baryons in proton-proton collisions, predicting higher diquark production rates than traditional methods, with implications for experimental verification.

Contribution

It introduces a duality approach accounting for independent parton scatterings, leading to increased diquark production cross sections in $pp$ collisions.

Findings

Diquark production cross section is larger than traditional models.

The approach aligns with potential experimental verification at LHCb.

Discusses contributions to double and associated quarkonium production.

Abstract

In present work we discuss the production of heavy quarkonia and diquarks in $pp$-interactions. The aim is to take into account the production of bound states of quarks originating from independent parton scatterings. This production is regulated by constraints on the invariant mass of constituents. Such an approach leads to larger value of the diquark production cross section than traditional consideration in single parton scattering. This production mechanism of doubly heavy baryons can sooner be verified by modern experiments (e.g. LHCb). We also discuss related contributions to double and associated quarkonium production.
