DESCRIPTION:*Speaker : Prof. Kwang Sik Jeong (Pusan National University)
 \n\n*Abstract : We explore gauge coupling unification and dark matter in 
 high scale supersymmetry where the scale of supersymmetry breaking is much
  above the weak scale. The gauge couplings unify as precisely as in low en
 ergy supersymmetry if the higgsinos\, whose mass does not break supersymme
 try\, are much lighter than those obtaining masses from supersymmetry brea
 king. The dark matter of the universe can then be explained by the neutral
  higgsino or the gravitino. High scale supersymmetry with light higgsinos 
 requires a large Higgs mixing parameter for electroweak symmetry breaking 
 to take place. It is thus naturally realized in models where superparticle
  masses are generated at loop level while the Higgs mixing parameter is in
 duced at tree level\, like in anomaly and gauge mediation of supersymmetry
  breaking.\n\nhttps://sshep.snu.ac.kr/event/7/
