Opening Address on behalf of Organizers • We welcome all participants with great pleasure. • This conference inherits GUT07. • This conference is sponsored by Yukawa Institute for Theoretical Physics and co-sponsored by Inoue Foundation for Science.
The Tohoku Earthquake • Just one year ago, Japan suffered from historical disaster - The Tohoku Earthquake - and lost more than twenty thousands precious lives. • More than three hundred thousands peoples are still forced to live refugee life. • We are always living with these peoples.
Japan thanks to so many supports from peoples around the world, and we do espepecially to friends who came here.
Let me comment on the prospect of GUT only in the next one sheet. GUT now enters into the precision science. GUT is testable. Only GUT can explain miscellaneousphenomena comprehensively as the SM does. We need the unambiguous priciples for model building where NO-GO theorems play very essential roles.
Horizontal Symmetry string theory F theory Continuous and discrete, No-Go (2) local and global but ? GUT in extra D Gauge-Higgs We need any No-Go Vertical Symmetry No-Go (3) Inflation Model GUT in 4D SUSY GUT No-Go(1) (1) Coleman-Mandula (2) No-Go of high-ranked Higgs etc. (3) Nelson-Seiberg th. is sublimated to NO-GO by Ratz et al.
Enjoy Workshop And Hope many many discussions !
