New strange pentaquarks
Marek Karliner, Jonathan R. Rosner

TL;DR
This paper analyzes the nature of newly observed strange pentaquarks, proposing they are hadronic molecules similar to non-strange pentaquarks, and predicts three additional states with specific mass shifts.
Contribution
It introduces the hypothesis that strange pentaquarks are hadronic molecules and predicts three new states based on this model.
Findings
Strange pentaquarks are likely hadronic molecules of ar D and ar D*.
Comparison with non-strange pentaquarks supports the molecular interpretation.
Predicts three new strange pentaquarks with higher masses.
Abstract
The new strange pentaquarks observed by LHCb are very likely hadronic molecules consisting of and We discuss the experimental evidence supporting this conclusion, pointing out the similarities and differences with the , and pentaquarks in the non-strange sector. The latter clearly are hadronic molecules consisting of and Following this line of thought, we predict three additional strange pentaquarks, consisting of and The masses of these states are expected to be shifted upwards by MeV with respect to the corresponding known strange pentaquarks.
