This work details the release of the CTEQ-TEA collaboration's updated set of parton distribution functions, CT18. These PDFs are a crucial input to almost all theory and experimental calculations carried out at the LHC and potentially other hadron colliders. The new set supersedes the CT14 analysis, incorporating additional data from the HERA and LHC experiments and providing alternative fits to explore the effect of different input assumptions.
