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

Noncommutative Gauge Dynamics From The String Worldsheet [PDF]
, 2000 We show how string theory can be used to reproduce the one-loop two-point photon amplitude in noncommutative U(1) gauge theory. Using a simple realization of the gauge theory in bosonic string theory, we extract from a string cylinder computation in the ...

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,

Energy Momentum Tensor and Marginal Deformations in Open String Field Theory [PDF]
, 2004 Marginal boundary deformations in a two dimensional conformal field theory correspond to a family of classical solutions of the equations of motion of open string field theory.

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 ...

Tadpoles and Closed String Backgrounds in Open String Field Theory [PDF]
, 2003 We investigate the quantum structure of Witten's cubic open bosonic string field theory by computing the one-loop contribution to the open string tadpole using both oscillator and conformal field theory methods.

Gauge and General Coordinate Invariance in Non-Polynomial Closed String Field Theory [PDF]
, 1991 An appropriate field configuration in non-polynomial closed string field theory is shown to correspond to a general off-shell field configuration in low energy effective field theory.
