Generalized Kac-Moody Algebras from CHL dyons
Suresh Govindarajan, K Gopala Krishna
We provide evidence for the existence of a family of generalized Kac-Moody(GKM) superalgebras, G_N, whose Weyl-Kac-Borcherds denominator formula gives rise to a genus-two modular f…
On The Stability of Non-Supersymmetric Attractors in String Theory
Suresh Nampuri, Prasanta K. Tripathy, Sandip P. Trivedi
We study non-supersymmetric attractors obtained in Type IIA compactifications on Calabi Yau manifolds. Determining if an attractor is stable or unstable requires an algebraically c…
Non-Supersymmetric Attractors in String Theory
Prasanta K. Tripathy, Sandip P. Trivedi
We find examples of non-supersymmetric attractors in Type II string theory compactified on a Calabi Yau three-fold. For a non-supersymmetric attractor the fixed values to which the…
Fermion Zero Modes in the Presence of Fluxes and a Non-perturbative Superpotential
Dieter Lust, Susanne Reffert, Waldemar Schulgin +1
We study the effect of background fluxes of general Hodge type on the supersymmetry conditions and on the fermionic zero modes on the world-volume of a Euclidean M5/D3-brane in M-t…
Gaugino Condensation and Nonperturbative Superpotentials in Flux Compactifications
Lars Goerlich, Shamit Kachru, Prasanta K. Tripathy +1
There are two known sources of nonperturbative superpotentials for Kähler moduli in type IIB orientifolds, or F-theory compactifications on Calabi-Yau fourfolds, with flux: Euclide…
Flux Compactifications on Calabi-Yau Threefolds
Alexander Giryavets, Shamit Kachru, Prasanta K. Tripathy +1
The presence of RR and NS three-form fluxes in type IIB string compactification on a Calabi-Yau orientifold gives rise to a nontrivial superpotential W for the dilaton and complex…
