Abstract

We show that the recently proposed tetraquark hypothesis for the nature of the χc1(3872) results in a formalism for inclusive production rates that has no unknown parameters. We employ this formalism to compute hadroproduction rates of χc1(3872) at the Large Hadron Collider, which agree with measured prompt and nonprompt cross sections. Thus, we find that the tetraquark hypothesis for χc1(3872) is well supported by hadroproduction data.
