Branes and instantons at angles and the F-theory lift of O(1) instantons
Mirjam Cvetič, Iñaki García-Etxebarria, Robert Richter
We discuss the physics of D-branes and D-brane instantons intersecting at angles, focusing on the (non)generation of a superpotential in the worldvolume theory of the branes. This…
Mass Hierarchies vs. Proton Decay in MSSM Orientifold Compactifications
Mirjam Cvetič, James Halverson, Robert Richter
We review two systematic bottom-up analyses of MSSM quivers recently performed by the authors. We extend the analysis of arXiv:0905.3379 by including constraints arising from proto…
Mass Hierarchies from MSSM Orientifold Compactifications
Mirjam Cvetič, James Halverson, Robert Richter
We investigate phenomenologically viable four- and five-stack MSSM D-brane quivers which exhibit realistic fermion mass hierarchies. In our analysis, the mass hierarchies arise eit…
Greybody Factors and Charges in Kerr/CFT
Mirjam Cvetic, Finn Larsen
We compute greybody factors for near extreme Kerr black holes in D=4 and D=5. In D=4 we include four charges so that our solutions can be continuously deformed to the BPS limit. In…
Non-Abelian Black Holes in D=5 Maximal Gauged Supergravity
M. Cvetic, H. Lu, C. N. Pope
We investigate static non-abelian black hole solutions of anti-de Sitter Einstein-Yang-Mills-Dilaton gravity, which is obtained as a consistent truncation of five-dimensional maxim…
Realistic Yukawa Structures from Orientifold Compactifications
Mirjam Cvetič, James Halverson, Robert Richter
We perform a systematic analysis of globally consistent D-brane quivers which realize the MSSM, and analyze them with respect to their Yukawa couplings. Often, desired couplings ar…
Branes and instantons intersecting at angles
Mirjam Cvetič, Iñaki García-Etxebarria, Robert Richter
We study in detail the system of D6 branes and euclidean D2-brane instantons intersecting at angles in type IIA string theory. We find that in the absence of orientifolds the syste…
D-brane Instantons in Type II String Theory
Ralph Blumenhagen, Mirjam Cvetic, Shamit Kachru +1
We review recent progress in determining the effects of D-brane instantons in N=1 supersymmetric compactifications of Type II string theory to four dimensions. We describe the abst…
