Gauge-invariant action for free string field theory with boundary
Carlo Maccaferri, Alberto Ruffino, Jakub Vošmera
We construct fully gauge-invariant kinetic terms for open and closed string field theories on a target space with boundary. This is realized by promoting the gauge parameters at th…
Boundary Modes in String Field Theory
Carlo Maccaferri, Riccardo Poletti, Alberto Ruffino +1
We discuss the construction of boundary contributions to free string field theory actions in the context of the bosonic string. We show that it is generally possible to obtain a we…
Bulk-induced D-brane deformations and the string coupling constant
Carlo Maccaferri, Alberto Ruffino, Jakub Vošmera
We consider computing the on-shell disk action of open-closed string field theory as a gauge-invariant way of capturing the shift in D-brane tension that is induced by a deformatio…
Adding stubs to quantum string field theories
Carlo Maccaferri, Riccardo Poletti, Alberto Ruffino +1
Generalizing recent work by Schnabl-Stettinger and Erbin-Firat, we outline a universal algebraic procedure for `adding stubs' to string field theories obeying the BV quantum master…
Open-Closed String Field Theory in the Large Limit
Carlo Maccaferri, Alberto Ruffino, Jakub Vošmera
We use the new nilpotent formulation of open-closed string field theory to explore the limit where the number of identical D-branes of the starting background is large. By refo…
The Nilpotent Structure of Open-Closed String Field Theory
Carlo Maccaferri, Alberto Ruffino, Jakub Vošmera
In this note we revisit the homotopy-algebraic structure of oriented bosonic open-closed string field theory and we give a new compact formulation in terms of a single cyclic open-…
