A method for modelling the prompt production of molecular states using the hadronic rescattering framework of the general-purpose Pythia event generator is introduced. Production cross sections of possible exotic hadronic molecules via hadronic rescattering at the LHC are calculated for the resonance, a possible tetraquark state, as well as three possible pentaquark states, , , and . For the states, the expected cross section from decays is compared to the hadronic-rescattering production. The cross section is compared to the fiducial cross-section measurement by LHCb and found to contribute at a level of . Finally, the expected yields of production from hadronic rescattering during Run 3 of LHCb are estimated. The prompt background is found to be significantly larger than the prompt signal from hadronic rescattering.
