Nonlinear N=2 Supersymmetry, Effective Actions and Moduli Stabilization
I. Antoniadis, J. P. Derendinger, T. Maillard
Nonlinear supersymmetry is used to compute the general form of the effective D-brane action in type I string theory compactified to four dimensions in the presence of internal magn…
Penrose Limits vs String Expansions
Matthias Blau, Sebastian Weiss
We analyse the relation between two a priori quite different expansions of the string equations of motion and constraints in a general curved background, namely one based on the co…
Remodeling the B-model
Vincent Bouchard, Albrecht Klemm, Marcos Marino +1
We propose a complete, new formalism to compute unambiguously B-model open and closed amplitudes in local Calabi-Yau geometries, including the mirrors of toric manifolds. The forma…
Metastable supergravity vacua with F and D supersymmetry breaking
Marta Gomez-Reino, Claudio A. Scrucca
We study the conditions under which a generic supergravity model involving chiral and vector multiplets can admit viable metastable vacua with spontaneously broken supersymmetry an…
Axionic symmetry gaugings in N=4 supergravities and their higher-dimensional origin
Jean-Pierre Derendinger, P. Marios Petropoulos, Nikolaos Prezas
We study the class of four-dimensional N=4 supergravities obtained by gauging the axionic shift and axionic rescaling symmetries. We formulate these theories using the machinery of…
Hidden Borcherds symmetries in Z_n orbifolds of M-theory and magnetized D-branes in type 0' orientifolds
Maxime Bagnoud, Luca Carlevaro
We study T^{11-D-q}xT^q/Z_n orbifold compactifications of 11D supergravity and M-theory by a purely algebraic method. Using the mapping between scalar fields of toroidally compacti…
