Abstract: A bstract We use the Born-Oppenheimer effective field theory factorization to compute the inclusive production cross sections of the χ c 1 (3872) and its partner in the bottomonium sector. In the same framework, we compute the production cross sections of the pentaquark states $$ {P}_{c\overline{c}}{(4312)}^{+} $$ P c c ¯ 4312 + , $$ {P}_{c\overline{c}}{(4457)}^{+} $$ P c c ¯ 4457 + , $$ {P}_{c\overline{c}}{(4380)}^{+} $$ P c c ¯ 4380 + and $$ {P}_{c\overline{c}}{(4440)}^{+} $$ P c 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.
