Fundamental Strings and Higher Derivative Corrections to d-Dimensional Black Holes
Amit Giveon, Dan Gorbonos, Merav Stern
We study aspects of d-dimensional black holes with two electric charges, corresponding to fundamental strings with generic momentum and winding on an internal circle. The perturbat…
Uplifted Metastable Vacua and Gauge Mediation in SQCD
Amit Giveon, Andrey Katz, Zohar Komargodski
Anomalously small gaugino masses are a common feature of various models of direct gauge mediation. This problem is closely related to the vacuum structure of the theory. In this pa…
Brane Dynamics and 3D Seiberg Duality on the Domain Walls of 4D N=1 SYM
Adi Armoni, Amit Giveon, Dan Israel +1
We study a three-dimensional U(k) Yang-Mills Chern-Simons theory with adjoint matter preserving two supersymmetries. According to Acharya and Vafa, this theory describes the low-en…
D-Terms and Supersymmetry Breaking from Branes
Amit Giveon, David Kutasov, Jock McOrist +1
Metastable supersymmetry breaking configurations of D-branes and NS5-branes in string theory often owe their existence to classical gravitational interactions between the branes. W…
Spontaneous SUSY Breaking in Various Dimensions
Amit Giveon, David Kutasov, Oleg Lunin
We generalize the ISS model of spontaneous supersymmetry breaking to lower dimensions. We also comment on the dynamics of the corresponding brane systems in string theory, and on p…
