Anomaly mediation in superstring theory [PDF]
AbstractWe study anomaly mediated supersymmetry breaking in type IIB string theory and use our results to test the supergravity formula for anomaly mediated gaugino masses. We compute 1‐loop gaugino masses for models of D3‐branes on orbifold singularities with 3‐form fluxes by calculating the annulus correlator of 3‐form flux and two gauginos in the ...

Stringy tachyonic instabilities of non-supersymmetric Ricci flat backgrounds
Superstring/M-theory compactified on compact Ricci flat manifolds have recently been conjectured to exhibit instabilities whenever the metrics do not have special holonomy.

One loop mass renormalization of unstable particles in superstring theory [PDF]
A bstractMost of the massive states in superstring theory are expected to undergo mass renormalization at one loop order. Typically these corrections should contain imaginary parts, indicating that the states are unstable against decay into lighter ...

Tree-level S-matrix of superstring field theory with homotopy algebra structure
We show that the tree-level S-matrices of the superstring field theories based on the homotopy-algebra structure agree with those obtained in the first-quantized formulation. The proof is given in detail for the heterotic string field theory.

Galilean Supersymmetry in 2+1 Dimensions [PDF]
We review work done in collaboration with C.B. Thorn on Super-Galilei invariant field theory and its application to the reformulation of superstring theory in terms of constituent superstring-bits.Comment: 10 pages, Latex.

String Field Theory from IIB Matrix Model [PDF]
We derive Schwinger-Dyson equations for the Wilson loops of a type IIB matrix model. Superstring coordinates are introduced through the construction of the loop space.

Solving String Field Equations: New Uses for Old Tools [PDF]
It is argued that the (NS-sector) superstring field equations are integrable, i.e. their solutions are obtainable from linear equations. We adapt the 25-year-old solution-generating "dressing" method and reduce the construction of nonperturbative ...

Yang-Baxter deformations of the AdS5 × S 5 pure spinor superstring
We present integrable Yang-Baxter deformations of the AdS5 × S 5 pure spinor superstring theory which were obtained by using homological perturbation theory. Its equations of motion and BRST symmetry are discussed and its Lax connection is derived.
