A multitrace deformation of ABJM theory
Ben Craps, Thomas Hertog, Neil Turok
Motivated by the study of big crunch singularities in asymptotically spacetimes, we consider a marginal triple trace deformation of ABJM theory. The deformation corresponds…
Chiral Symmetry Breaking with non-SUSY D7-branes in ISD backgrounds
Anatoly Dymarsky, Stanislav Kuperstein, Jacob Sonnenschein
Supersymmetric probe branes satisfy the kappa-symmetry condition which ensures that the action is minimized with respect to both variations of the embedding and of the world-volume…
N=2 world-sheet approach to D-branes on generalized Kaehler geometries: II. Dualities
Alexander Sevrin, Wieland Staessens, Alexander Wijns
Following the general formalism reviewed in 0810.5355 [hep-th] we present several examples of possible D3-brane configurations on four-dimensional generalized Kaehler geometries. W…
Two Loop R-Symmetry Breaking
Antonio Amariti, Alberto Mariotti
We analyze two loop quantum corrections for pseudomoduli in O'Raifeartaigh like models. We argue that R-symmetry can be spontaneously broken at two loop in non supersymmetric vacua…
Can free strings propagate across plane wave singularities?
Ben Craps, Frederik De Roo, Oleg Evnin
We study free string propagation in families of plane wave geometries developing strong scale-invariant singularities in certain limits. We relate the singular limit of the evoluti…
N = 2 world-sheet approach to D-branes on generalized Kaehler geometries: I. General formalism
Alexander Sevrin, Wieland Staessens, Alexander Wijns
We present an N = 2 world-sheet superspace description of D-branes on bihermitian or generalized Kaehler manifolds. To accomplish this, D-branes are considered as boundary conditio…
