Title of talk4 Albright, Anderson, Babu, Barr, Barbieri, Berezhiani, Blazek, Carena, Chang, Dermisek, Dimopoulos, Hall, Masiero, Murayama, Pati, Raby, Romanino, Rossi, Starkman, Wagner, Wilczek, Wiesenfeldt, Willenbrock Possible UV completion to strings !! Effective higher dimension operators, Small reps + Many predictions !! Hierarchical SO(10) Yukawas

5
Note, CANNOT predict top mass due to large SUSY threshold corrections to bottom and tau mass So instead use Yukawa unification to predict soft SUSY breaking masses !!

6
MSO 10 SM Fit t,b,tau requires TM

Roughly ½ comes From RG running from Radiative EWSB requires Blazek, Dermisek & Raby Just so Note, this is difficult in bottom – up approach !!
