Abstract: A bstractWe calculate the corrections to the open string BRST charge in boundary string field theory and show that the expansion coefficients agree with the perturbative S-matrix to all orders. In mathematical terms, boundary string… read more here.

Abstract: A bstractWe report on progress in formulating a field theory of tensionless strings in AdS3, starting from the dual large-N symmetric orbifold CFT. We propose a set of field equations which are gauge invariant under… read more here.

Abstract: Abstract In this paper, which is the last of a series including [1, 2] we first verify that the two open-closed effective potentials derived in the previous paper from the WZW theory in the large… read more here.

DOI: 10.1093/ptep/ptz051
Abstract: We construct a complete heterotic string field theory that includes both the Neveu-Schwarz and Ramond sectors. We give a construction of general string products, which realizes a cyclic L-infinity structure and thus provides with a… read more here.
