Proof of new S-matrix formula from classical solutions in open string field theory (or, Deriving on-shell open string field amplitudes without using Feynman rules, Part II)
Toru Masuda, Hiroaki Matsunaga, Toshifumi Noumi
We study relation between the gauge invariant quantity obtained in [arXiv:1908.09784] and the Feynman diagrams in the dressed gauge in the open cubic string field…
Perturbative path-integral of string field and the structure of the BV master equation
Toru Masuda, Hiroaki Matsunaga
The perturbative path-integral gives a morphism of the (quantum) structure intrinsic to each quantum field theory, which we show explicitly on the basis of the homolo…
Deriving on-shell open string field amplitudes without using Feynman rules
Toru Masuda, Hiroaki Matsunaga
We present a series of new gauge invariant quantities in Witten's open string field theory. They are defined for a given set of open string states which satisfy the physical state…
Rolling Near the Tachyon Vacuum
Theodore Erler, Toru Masuda, Martin Schnabl
In a linear dilaton background, it has been argued that an unstable D-brane can decay to the tachyon vacuum without leaving behind a remnant of tachyon matter. Here we address the…
Vector profile and gauge invariant observables of string field theory solutions for constant magnetic field background
Nobuyuki Ishibashi, Isao Kishimoto, Toru Masuda +1
We study profiles and gauge invariant observables of classical solutions corresponding to a constant magnetic field on a torus in open string field theory. We numerically find that…
Topological defects in open string field theory
Toshiko Kojita, Carlo Maccaferri, Toru Masuda +1
We show how conformal field theory topological defects can relate solutions of open string field theory for different boundary conditions. To this end we generalize the results of…
