Inclusive hadroproduction of ${\chi }_{c1}(3872)$, $X_b$ and pentaquarks

Abstract

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.
