We describe a new correspondence between four-dimensional conformal field theories with extended supersymmetry and two-dimensional chiral algebras. The meromorphic correlators of the chiral algebra…

We study the $${\mathcal{N}=2}$$ four-dimensional superconformal index in various interesting limits, such that only states annihilated by more than one supercharge contribute. Extrapolating from the…
Tachyon potentials, star products and universality
- L. Rastelli, B. Zwiebach
- Mathematics
- 30 June 2000
We develop an efficient recursive method to evaluate the tachyon potential using the relevant universal subalgebra of the open string star algebra. This method, using off-shell versions of Virasoro…

- Physics, Mathematics
- 19 April 2011
In this letter we describe a new powerful duality, relating physics in four and in two dimensions. We will argue that for a large class of four-dimensional superconformal gauge theories, non-trivial…
Classical solutions in string field theory around the tachyon vacuum
- L. Rastelli, A. Sen, B. Zwiebach
- Physics
- 19 February 2001
In a previous paper [hep-th/0012251] we proposed a simple class of actions for string field theory around the tachyon vacuum. In this paper we search for classical solutions describing D-branes of…
The bootstrap program for boundary CFTd
- P. Liendo, L. Rastelli, B. V. Rees
- Mathematics
- 16 October 2012
A bstractWe study the constraints of crossing symmetry and unitarity for conformal field theories in the presence of a boundary, with a focus on the Ising model in various dimensions. We show that an…

Ghost Structure and Closed Strings in Vacuum String Field Theory
- D. Gaiotto, L. Rastelli, A. Sen, B. Zwiebach
- Physics
- 14 November 2001
We complete the construction of vacuum string field theory by proposing a canonical choice of ghost kinetic term – a local insertion of the ghost field at the string midpoint with an infinite…
