Hadroproduction data support tetraquark hypothesis for $\chi_{c1} (3872)$

TL;DR

This paper demonstrates that a parameter-free formalism based on the tetraquark hypothesis accurately predicts the production rates of the $chi_{c1}(3872)$ at the LHC, aligning well with experimental data.

Contribution

It introduces a novel, parameter-free formalism for $chi_{c1}(3872)$ production based on the tetraquark hypothesis, supported by collider data.

Findings

The formalism matches measured prompt and nonprompt cross sections.

Hadroproduction data strongly support the tetraquark hypothesis.

No unknown parameters are needed in the formalism.

Abstract

We show that the recently proposed tetraquark hypothesis for the nature of the $\chi_{c1}(3872)$ results in a formalism for inclusive production rates that has no unknown parameters. We employ this formalism to compute hadroproduction rates of $\chi_{c1}(3872)$ at the Large Hadron Collider, which agree with measured prompt and nonprompt cross sections. Thus we find that the tetraquark hypothesis for $\chi_{c1}(3872)$ is well supported by hadroproduction data.
