Abstract

We show that the recently proposed tetraquark hypothesis for the nature of the χ_c1(3872) results in a formalism for inclusive production rates that has no unknown parameters. We employ this formalism to compute hadroproduction rates of χ_c1(3872) at the Large Hadron Collider, which agree with measured prompt and nonprompt cross sections. Thus we find that the tetraquark hypothesis for χ_c1(3872) is well supported by hadroproduction data.
