摘要

We use the Born-Oppenheimer effective field theory factorization to compute the inclusive production cross sections of the χc1(3872) and its partner in the bottomonium sector. In the same framework, we compute the production cross sections of the pentaquark states P c c ¯ 4312 + \( {P}_{c\overline{c}}{(4312)}^{+} \) , P c c ¯ 4457 + \( {P}_{c\overline{c}}{(4457)}^{+} \) , P c c ¯ 4380 + \( {P}_{c\overline{c}}{(4380)}^{+} \) and P c c ¯ 4440 + \( {P}_{c\overline{c}}{(4440)}^{+} \) within two possible scenarios for the Born-Oppenheimer potentials. Also for pentaquarks, we extend the results to the bottomonium sector. All our results are genuine predictions that do not involve fits to prompt hadroproduction data.
