Abstract
Abstract In this study, we investigate the , , , , , , , and pentaquark molecular states with and without strangeness via the QCD sum rules in detail, focusing on the light flavor, , breaking effects, and make predictions for new pentaquark molecular states besides assigning , , , , and self-consistently. In the future, we can search for these pentaquark molecular states in the decay of , , and . Furthermore, we discuss high-dimensional vacuum condensates in detail.
