Superstring field theory and the Wess-Zumino-Witten action [PDF]
Journal of High Energy Physics, 2017 We describe a notion of “higher” Wess-Zumino-Witten-like action which is natural in the context of superstring field theories formulated in the large Hilbert space.

RECENT PROGRESS IN SUPERSTRING THEORY
The Ninth Marcel Grossmann Meeting, 2002 Superstring theory has continued to develop at a rapid clip in the past few years. Following a quick review of some of the major discoveries prior to 1998, this talk focuses on a few of the more recent developments. The topics I have chosen to present are 1) the use of K-theory to classify conserved charges carried by D-branes; 2) tachyon condensation ...

Resolving Witten's Superstring Field Theory [PDF]
Journal of High Energy Physics, 2013 We regulate Witten's open superstring field theory by replacing the picture-changing insertion at the midpoint with a contour integral of picture changing insertions over the half-string overlaps of the cubic vertex.

Reality of superstring field theory action [PDF]
Journal of High Energy Physics, 2016 A bstractWe determine the reality conditions on the string fields that make the action for heterotic and type II string field theories real.

Open-closed homotopy algebra in superstring field theory [PDF]
Progress of Theoretical and Experimental Physics, 2022 We construct open-closed superstring interactions based on the open-closed homotopy algebra structure. It provides a classical open superstring field theory on general closed-superstring-field backgrounds described by classical solutions of the ...

Superstring Loop Amplitudes from the Field Theory Limit. [PDF]
Physical Review Letters, 2021 We propose a procedure to determine the moduli-space integrands of loop-level superstring amplitudes for massless external states in terms of the field theory limit. We focus on the type II superstring.

D=5 holomorphic Chern-Simons and the pure spinor superstring
Journal of High Energy Physics, 2023 The physical states of D=5 holomorphic Chern-Simons theory correspond to on-shell D=10 open superstring states in the cohomology of q +, where q + is one of the 16 spacetime supersymmetry generators.

Modular forms and SL(2, ℤ)-covariance of type IIB superstring theory [PDF]
Journal of High Energy Physics, 2019 A bstractThe local higher-derivative interactions that enter into the low-energy expansion of the effective action of type IIB superstring theory with constant complex modulus generally violate the U(1) R-symmetry of IIB supergravity by qU units.

Theory of ultracold superstrings [PDF]
Physical Review A, 2006 The combination of a vortex line in a one-dimensional optical lattice with fermions bound to the vortex core makes up an ultracold superstring. We give a detailed derivation of the way to make this supersymmetric string in the laboratory. In particular, we discuss the presence of a fermionic bound state in the vortex core and the tuning of the laser ...

Instanton solutions in open superstring field theory
Journal of High Energy Physics, 2022 Open superstring field theory admits a “hybrid” formulation where N = 1 D = 4 supersymmetry is manifest for Calabi-Yau compactifications to four dimensions.
