Description

Currently, there are only six cascade states (out of 44 predicted) that have at least a three-star rating in the PDG, with the production mechanism of these states still remaining mostly elusive. Cascade studies are promising as a tool to differentiate genuine quark states from hadronic molecules, since we have the ability to measure the line shape in various decay branches with unprecedented precision. Because we have ss in the final state, the number of diquark configurations we can have is constrained. As a doubly strange final state, it also gives us access to various exotic channels which might be viable for analysis.

This work focuses on the analysis of CLAS12 data collected at Jefferson Lab to study the production mechanisms and decays of excited cascade baryon states that are not well established or missing, with the aim of determining
their branching ratios and quantum numbers. Additionally, the possibility of exploring doubly strange exotics, an analogue of double charm exotics recently observed at LHCb, in the same dataset will be discussed.
