DESCRIPTION:Title: <a href="https://researchseminars.org/talk/FHD3/2/">Fro
 m strings to QCD: The study of doubly heavy hadrons</a>\nby Oleg Andreev (
 Munich University) as part of Frontiers of Holographic Duality-3\n\n\nAbst
 ract\nWe will discuss the string theory constructions for the $QQq$ and $Q
 Q\\bar q\\bar q $systems. Following the hadro-quarkonium picture the poten
 tial  is a function of separation between the heavy quarks. The results sh
 ow the universality of the string tension and factorization at small separ
 ations expected from heavy quark-diquark symmetry. The potentials look ver
 y similar at small quark separations but at larger separations they differ
 . The reason for this is that the flattening of the potentials happens at 
 two well-separated scales as follows from the two different mechanisms: st
 ring breaking by light quarks for QQq and string junction annihilation for
  $QQ\\bar q\\bar q$.\n
