A Non-local "Boundary'' Term for Two-Point Amplitudes in String Field Theory
Yasu Gen, Hiroaki Matsunaga, Jojiro Totsuka
We propose a new ``boundary'' term in free bosonic string field theory. Here, the term ``boundary'' refers to a contribution introduced to restore the cyclicity broken by the inser…
Mapping between Witten and Lightcone String Field Theories
Theodore Erler, Hiroaki Matsunaga
We propose a transformation between the off-shell field variables of Witten's open bosonic string field theory and the traditional lightcone string field theory of Kaku and Kikkawa…
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…
Light-cone reduction of Witten's open string field theory
Hiroaki Matsunaga
We elucidate some exact relations between light-cone and covariant string field theories on the basis of the homological perturbation lemma for . The covariant string…
On the BV formalism of open superstring field theory in the large Hilbert space
Hiroaki Matsunaga, Mitsuru Nomura
We construct several BV master actions for open superstring field theory in the large Hilbert space. First, we show that a naive use of the conventional BV approach breaks down at…
Hidden gauge reducibility of superstring field theory and Batalin-Vilkovisky master action
Hiroaki Matsunaga
In this paper, we show that there exists a hidden gauge reducibility in superstring field theory based on the small dynamical string field whose gauge varia…
Notes on the Wess-Zumino-Witten-like structure: triplet and NS-NS superstring field theory
Hiroaki Matsunaga
In the NS-NS sector of superstring field theory, there potentially exist three nilpotent generators of gauge transformations and two constraint equations: It makes the gauge algebr…
structure and alternative action for WZW-like superstring field theory
Keiyu Goto, Hiroaki Matsunaga
We propose new gauge invariant actions for open NS, heterotic NS, and closed NS-NS superstring field theories. They are based on the large Hilbert space, and have Wess-Zumino-Witte…
Comments on complete actions for open superstring field theory
Hiroaki Matsunaga
We clarify a Wess-Zumino-Wtten-like structure including Ramond fields and propose one systematic way to construct gauge invariant actions: Wess-Zumino-Witten-like complete action $…
On-shell equivalence of two formulations for superstring field theory
Keiyu Goto, Hiroaki Matsunaga
In this paper we derive the condition providing the on-shell equivalence of -type and WZW-like formulations for superstring field theory. We construct the NS string pro…
Nonlinear gauge invariance and WZW-like action for NS-NS superstring field theory
Hiroaki Matsunaga
We complete the construction of a gauge-invariant action for NS-NS superstring field theory in the large Hilbert space begun in arXiv:1305.3893 by giving a closed-form expression f…
Construction of a Gauge-Invariant Action for Type II Superstring Field Theory
Hiroaki Matsunaga
We construct a gauge-invariant action for covariant type II string field theory in the NS-NS sector. Our construction is based on the large Hilbert space description and Zwiebach's…
