DESCRIPTION:Speakers: Isaac Vidana (Istituto Nazionale di Fisica Nucleare)
 \nIn this exploratory work  we analyze the possible existence of a strange
 ness $S=-3$\, isospin $I=1$ pentaquark  state $P_{sss}$ generated dynamica
 lly from the $\\bar{K}\\Xi$ interaction. We employ a unitarized scheme in 
 coupled channels based on the chiral Lagrangian expanded up to next-to-lea
 ding order (NLO)\, and show that the inclusion of the NLO terms can be cru
 cial to provide the necessary attraction that favors the existence of such
  triply strange pentaquark. The $\\bar{K}\\Xi$ femtoscopic correlation fun
 ctions are calculated as example of a possible experimental measurement in
  which a direct signal of the $P_{sss}$ state could be observed.\n\nhttps:
