Abstract: We continue our analysis of open string field theory based on A∞-algebras obtained from Witten’s theory by attaching stubs to the elementary vertex. Classical solutions of the new theory can be obtained from known analytic… read more here.

DOI: 10.1007/jhep04(2025)039
Abstract: Open string amplitudes at tree level have been studied for over fifty years. However, there is no known analytic form for general n-point amplitudes, and their conventional representation in terms of worldsheet integrals does not… read more here.

DOI: 10.1007/jhep06(2019)076
Abstract: A bstractIn this article, we explicitly demonstrate that, for a sufficiently generic class of examples, an open string embedded in an AdS-background yields an effective Schwarzian action and, in the semi-classical description, the fluctuation modes… read more here.

DOI: 10.1007/jhep06(2019)086
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 here report a possibility of detecting the open string pair production from the system of a D3 brane, taken as our own (1 + 3)-dimensional world and carrying its worldvolume collinear electric and… read more here.
