We use the Born--Oppenheimer effective field theory factorization to compute the inclusive production cross sections of the $\chi_{ c1}(3872)$ and its partner in the bottomonium sector. In the same framework, we compute the production cross sections of the pentaquark states $P_{ c\bar{ c}}(4312)^+$, $P_{ c\bar{ c}}(4457)^+$, $P_{ c\bar{ c}}(4380)^+$ and $P_{ c\bar{ c}}(4440)^+$ 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.
