Closed string deformations in open string field theory. Part II. Superstring
Journal of High Energy Physics, 2021 This is the second paper of a series of three. We construct effective open-closed superstring couplings by classically integrating out massive fields from open superstring field theories coupled to an elementary gauge invariant tadpole proportional to an

The closed string field theory action vanishes
Journal of High Energy Physics, 2022 Using the dilaton theorem, we show that the classical action of closed string field theory vanishes on-shell.

Closed string cohomology in open string field theory [PDF]
Journal of High Energy Physics, 2011 We show that closed string states in bosonic string field theory are encoded in the cyclic cohomology of cubic open string field theory (OSFT) which, in turn, classifies the deformations of OSFT. This cohomology is then shown to be independent of the open string background.

A superstring field theory for supergravity
Journal of High Energy Physics, 2017 A covariant closed superstring field theory, equivalent to classical tendimensional Type II supergravity, is presented. The defining conformal field theory is the ambitwistor string worldsheet theory of Mason and Skinner.

String field theory solution for any open string background. Part II
Journal of High Energy Physics, 2020 Generalizing previous work, we give a new analytic solution in Witten’s open bosonic string field theory which can describe any open string background. The central idea is to use Riemann surface degenerations as a mechanism for taming OPE singularities ...

String cosmology — Large-field inflation in string theory [PDF]
International Journal of Modern Physics A, 2015 This is a short review of string cosmology. We wish to connect string-scale physics as closely as possible to observables accessible to current or near-future experiments. Our possible best hope to do so is a description of inflation in string theory. The energy scale of inflation can be as high as that of Grand Unification (GUT). If this is the case,

Light strings and strong coupling in F-theory
Journal of High Energy Physics, 2023 We consider 4d N $$ \mathcal{N} $$ = 1 theories arising from F-theory compactifications on elliptically-fibered Calabi-Yau four-folds and investigate the non-perturbative structure of their scalar field space beyond the large volume/large complex ...

Field theory questions for string theory answers [PDF]
Nuclear Physics B, 1997 We discuss the field theory of 3-brane probes in F-theory compactifications in two configurations, generalizing the work of Sen and of Banks, Douglas and Seiberg. One configuration involves several parallel 3-brane probes in F-theory compactified on $T^4/Z_2$, while the other involves a compactification of F-theory on $T^6/Z_2 x Z_2$ (which includes ...

Light-cone reduction of Witten’s open string field theory
Journal of High Energy Physics, 2019 We elucidate some exact relations between light-cone and covariant string field theories on the basis of the homological perturbation lemma for A ∞.
