Maximal supergravity from IIB flux compactifications”, Phys
 Lett. B583
"... Using a recently proposed grouptheoretical approach, we explore novel gaugings of maximal supergravity in four dimensions with gauge group embeddings that can be generated by fluxes of IIB string theory. The corresponding potentials are positive without stationary points. Some allow domain wall sol ..."

Stringy Instantons in IIB Brane Systems
, 2008
"... In this note, we study Dbrane instantons which intersect N = 1 supersymmetric configurations of spacefilling Dbranes in general CalabiYau compactifications of type IIB string theory. Our focus is on rigid “stringy instantons ” – those which cannot be interpreted as YangMills instantons in a no ..."

Dbrane Deconstructions in IIB Orientifolds

"... With model building applications in mind, we collect and develop basic techniques to analyze the landscape of D7branes in type IIB compact CalabiYau orientifolds, in three different pictures: Ftheory, the D7 worldvolume theory and D9antiD9 tachyon condensation. A significant complication is th ..."

de Sitter string vacua from supersymmetric Dterms
 JHEP
, 2003
"... Abstract: We propose a new mechanism for obtaining de Sitter vacua in type IIB string theory compactified on (orientifolded) CalabiYau manifolds similar to those recently studied by Kachru, Kallosh, Linde and Trivedi (KKLT). dS vacuum appears in KKLT model after uplifting an AdS vacuum by adding an ..."

Generalised G2structures and type IIB superstrings
, 2004
"... The recent mathematical literature introduces generalised geometries which are defined by a reduction from the structure group SO(d,d) of the vector bundle T d ⊕ T d ∗ to a special subgroup. In this article we show that compactification of IIB superstring vacua on 7manifolds with two covariantly co ..."

An exact prediction of N = 4 SUSYM theory for string theory
 J. Math. Phys
, 2001
"... We show that the expectation value of a circular BPSWilson loop in N = 4 SUSYM can be calculated exactly, to all orders in a 1/N expansion and to all orders in g 2 N. Using the AdS/CFT duality, this result yields a prediction of the value of the string amplitude with a circular boundary to all orde ..."

Geometric and NonGeometric Compactifications Of IIB Supergravity
, 2006
"... Complimentary geometric and nongeometric consistent reductions of IIB supergravity are studied. The geometric reductions on the identified group manifold X = G/Γ are found to have a gauge symmetry with Lie algebroid structure, generalising that found in similar reductions of the Bosonic string theo ..."

N = 4 Supergravity Lagrangian for Type IIB
, 2003
"... We derive the Lagrangian and the transformation laws of N = 4 gauged supergravity coupled to matter multiplets whose σmodel of the scalars is SU(1,1)/U(1)⊗ SO(6,6 + n)/SO(6) ⊗ SO(6 + n) and which corresponds to the effective Lagrangian of the Type IIB string compactified on the T 6 /Z2 orientifold ..."

Fundamental Strings and Dstrings in the IIB Matrix Model
, 2008
"... The matrix model for IIB Superstring proposed by Ishibashi, Kawai, Kitazawa and Tsuchiya is investigated. Consideration of planar and nonplanar diagrams suggests that the large N perturbative expansion is consistent with the double scaling limit proposed by the above authors. We write down a Wilson ..."

Three Family Type IIB Orientifold String

We present an explicit threefamily example with the gauge group (U(4)×U(2)×SU(2)×SU(2)) 2 ×(U(6)×Sp(4)) 2 and give the particle spectrum and the trilinear superpotential. Emphasizing t ..."
