Einstein gravity from the spinning particle
Roberto Bonezzi, Adiel Meyer, Ivo Sachs
We obtain a manifestly background independent BRST quantization of the supersymmetric spinning particle. We show that nilpotency of the BRST charge implies the Einstein…
Classical Open String Amplitudes and Boundary String Field Theory
Christoph Chiaffrino, Ivo Sachs
Abstract: We show that boundary string field theory realizes the minimal model of open string field theory. More precisely, we observe that the expansion of the (co)homological vec…
Loops in Anti-de Sitter Space
Igor Bertan, Ivo Sachs
We obtain analytic results for the four-point amplitude, at one loop, of an interacting scalar field theory in four-dimensional, Euclidean anti-de Sitter space without exerting any…
boundary twist fields and the moduli space of D-branes
Luca Mattiello, Ivo Sachs
We revisit the boundary conformal field theory of twist fields. Based on the equivalence between twisted bosons on a circle and the orbifold theory at the critical radius, we provi…
