Flat-Directions in Grand Unification With Symmetry
S. M. Barr, Bumseok Kyae, Qaisar Shafi
It is shown that in SO(10) and SU(5) models having a symmetry, the requirement of breaking the unified group to the Standard Model leads to flat directions in the scalar p…
DF-strings from D33 as Cosmic Strings
Inyong Cho, Yoonbai Kim, Bumseok Kyae
We study Dirac-Born-Infeld type effective field theory of a complex tachyon and U(1)U(1) gauge fields describing a D33 system. Classical solutions of straig…
Global and Local D-vortices
Yoonbai Kim, Bumseok Kyae, Jungjai Lee
Codimension-two objects on a system of brane-antibrane are studied in the context of Born-Infeld type effective field theory with a complex tachyon and U(1)U(1) gauge field…
Inflation With Realistic Supersymmetric SO(10)
Bumseok Kyae, Qaisar Shafi
We implement inflation within a realistic supersymmetric SO(10) model in which the doublet-triplet splitting is realized through the Dimopoulos-Wilczek mechanism, the MSSM prob…
