Polchinski-Strassler does not uplift Klebanov-Strassler
Iosif Bena, Mariana Grana, Stanislav Kuperstein +1
Anti-D3-branes at the tip of the Klebanov-Strassler solution with D3-charge dissolved in fluxes give rise, in the probe approximation, to a metastable state. The fully back-reacted…
Generalized N=1 and N=2 structures in M-theory and type II orientifolds
Mariana Graña, Hagen Triendl
We consider M-theory and type IIA reductions to four dimensions with N=2 and N=1 supersymmetry and discuss their interconnection. Our work is based on the framework of Exceptional…
Anti-D3's - Singular to the Bitter End
Iosif Bena, Mariana Grana, Stanislav Kuperstein +1
We study the full backreaction of anti-D3 branes smeared over the tip of the deformed conifold. Requiring the 5-form flux and warp factor at the tip to be that of anti-D3 branes, w…
Gauged Double Field Theory
Mariana Graña, Diego Marques
We find necessary and sufficient conditions for gauge invariance of the action of Double Field Theory (DFT) as well as closure of the algebra of gauge symmetries. The so-called wea…
