Tree-Level Stability Without Spacetime Fermions: Novel Examples in String Theory
Dan Israel, Vasilis Niarchos
Is perturbative stability intimately tied with the existence of spacetime fermions in string theory in more than two dimensions? Type 0'B string theory in ten-dimensional flat spac…

Comments on geometric and universal open string tachyons near fivebranes
Dan Israel
In a recent paper (hep-th/0703157), Sen studied unstable D-branes in NS5-branes backgrounds and argued that in the strong curvature regime the universal open string tachyon (on D-b…

Orientifolds in N=2 Liouville Theory and its Mirror
Dan Israel, Vasilis Niarchos
We consider unoriented strings in the supersymmetric SL(2,R)/U(1) coset, which describes the two-dimensional Euclidean black hole, and its mirror dual N=2 Liouville theory. We anal…
