DESCRIPTION:Speakers: Elena G. Ferreiro (Universidad de Santiago de Compos
 tela)\nThe behavior of quarkonia and open-heavy flavour hadrons in hadroni
 c collisions provide a unique testing ground for understanding quantum chr
 omodynamics (QCD). Although there has been significant progress\, our unde
 rstanding of hadronic collisions has been challenged by the observation of
  intriguing effects in high-multiplicity proton-proton and proton-Pb colli
 sions\, such as the discovery of correlations and the suppression of quark
 onium excited states in those systems. Those phenomena show a smooth conti
 nuation of heavy-ion features to small systems and lower density\, whose o
 rigin is still not clear. Two serious contenders remain today as possible 
 explanations\, one based on initial-state correlations and another that re
 quires final-state interactions to be at play.\nIn this talk\, I will pres
 ent different results\, considering the possibility of final-state interac
 tions for the explanation of quarkonium excited states. Moreover\, the str
 ucture of exotic resonances that do not trivially fit the usual quark mode
 l expectations has been a matter of intense scientific debate during the l
 ast two decades. I will show that a possible way of estimating the nature 
 of these states is to study their behavior when immersed in QCD matter.\n\
