DESCRIPTION:Speakers: Dr. MURAMATSU\, Yu (Nagoya University)\nWe show that
  the sizable $D$-term contributions to sfermion mass spectrum can be signa
 tures of certain GUT\, $E_6\\times SU(2)_F\\times U(1)_A$ GUT. Note that t
 hese $D$-term contributions deviate the degenerate sfermion masses among d
 ifferent generations in this model. This is different from the previous wo
 rks which have argued the $D$-term contributions\, which deviate masses on
 ly between sfermions with different quantum charges\, as a signature of GU
 T with larger rank unification group. Such $D$-terms are strongly constrai
 ned by the FCNC processes if the SUSY breaking scale is the weak scale. Ho
 wever\, in $E_6\\times SU(2)_F\\times U(1)_A$\, natural SUSY type sfermion
  mass spectrum is obtained\, and if the masses of ${\\bf 10}_3$ sfermions 
  are larger than $O(1{\\rm TeV})$ to realize 126 GeV Higgs and the other s
 fermion masses are $O(10{\\rm TeV})$\, then sizable $D$-term contribution 
 is allowed. If the deviations by these $D$-terms can be observed in future
  experiments like 100 TeV proton collider or muon collider\, we may confir
 m the $E_6\\times SU(2)_F\\times U(1)_A$ GUT. And we produce some predicti
 ons for FCNC phenomena. This talk is based on arXiv:1405.4193 [hep-ph].\n\
