DESCRIPTION:Speakers: Dr. SUENAGA\, Daiki (RCNP\, Osaka University)\nWe pr
 opose a new type of structure for singly heavy baryons of $Qqq\\bar{q}q$ i
 n addition to the conventional one of $Qqq$. Based on chiral symmetry of t
 he light quarks\, we find $\\Lambda_c(2765)$ and $\\Xi_c(2967)$ are mostly
  $Qqq\\bar{q}q$ while $\\Lambda_c(2286)$ and $\\Xi_c(2470)$ are mostly $Qq
 q$. The masses of negative-parity baryons are predicted. We also derive a 
 mass formula and the extended Goldberger-Treiman relation that the masses 
 of the baryons satisfy.\n\nhttps://indico.nucleares.unam.mx/event/1541/ses
