SQCD Vacua and Geometrical Engineering
Radu Tatar, Ben Wetenhall
We consider the geometrical engineering constructions for the N = 1 SQCD vacua recently proposed by Giveon and Kutasov. After one T-duality, the geometries with wrapped D5 branes b…
Metastable Vacua and Complex Deformations
Radu Tatar, Ben Wetenhall
We use the non-normalizable complex deformations to describe the stringy realizations of the metastable vacua in N = 1, SU(N_c) SUSY theories with N_f > N_c massive fundamental fla…
Duality and Confinement in N=1 Supersymmetric Theories from Geometric Transitions
Kyungho Oh, Radu Tatar
We study large N dualities for a general class of N=1 theories realized on type IIB D5 branes wrapping 2-cycles of local Calabi-Yau threefolds or as effective field theories on D4…
A Note on Non-Commutative Field Theory and Stability of Brane-Antibrane Systems
Radu Tatar
It has been conjectured that a pair of D5 - anti D5 branes wrapped on some non-trivial two cycle of a Calabi-Yau manifold becomes a stable BPS D3 brane in the presence of a very la…
Comments on Brane Configurations with Semi-infinite D4 Branes
Kyungho Oh, Radu Tatar
We consider four dimensional supersymmetric gauge field theories from brane configurations with the matter content given by semi-infinite D4 branes ending on both sides of NS brane…
