Abstract |
In this exploratory work we analyze the possible existence of a strangeness S = -3, isospin I = 1 pentaquark state P-sss generated dynamically from the (K) over bar Xi interaction. We employ a unitarized scheme in coupled channels based on the chiral Lagrangian expanded up to next-to-leading order (NLO), and show that the inclusion of the NLO terms can be crucial to provide the necessary attraction that favors the existence of such triply strange pentaquark. The (K) over bar Xi femtoscopic correlation functions are calculated as example of a possible experimental measurement in which a direct signal of the P-sss state could be observed. |
