DESCRIPTION:A^ review on some recent progresses in our understanding of^ 5
 -quark componentsin baryons is presented. Two most possible configurations
 \, diquark-diquark-antiquark and meson cloud\, for the 5-quark components 
 in^ baryons are discussed. The diquark-diquark-antiquark picture gives a n
 atural^ explanation not only to the empirical indications for a positive^ 
 strangeness magnetic moment �/_s /\, positive strangeness radius of the^
  proton and single spin asymmetry but also the longstanding mass- reverse 
 problem of /N/*(1535)\, /N/*(1440)^ and Lambda*(1405) resonances as well a
 s the unusual decay pattern^ of the /N/*(1535) resonance. While the lowest
  1/2- baryon nonet may have large diquark-diquark-antiquark component\, th
 e lowest 1/2- baryon decuplet is proposedto have large vector-meson- baryo
 n components. Evidence for the "missing" members of these pictures is poin
 ted out and suggestions are made for detecting these predicted states from
  forthcoming experiments.\n\nhttps://indico.ific.uv.es/event/1619/
