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.

Green-Schwarz and pure spinor formulations of chiral strings
Journal of High Energy Physics, 2021 Bosonic and RNS chiral strings have been defined from a singular gauge fixing of the respective Polyakov and spinning string actions, enforcing, among other things, the finite nature of their physical spectra.

Refined topological amplitudes from the Ω-background in string theory
Journal of High Energy Physics, 2022 It was recently shown that the N $$ \mathcal{N} $$ = 2 string topological amplitudes in the heterotic weak coupling limit generate a six-dimensional Melvin space, providing a description of the Ω-background in string theory, where string propagation can ...

Normal form of nilpotent vector field near the tip of the pure spinor cone
Journal of High Energy Physics, 2021 Pure spinor formalism implies that supergravity equations in space-time are equivalent to the requirement that the worldsheet sigma-model satisfies certain properties.

A New Approach to String Theory
Universe, 2023 In the present paper, we consider quantum theories obtained through the quantization of classical theories with first-class constraints assuming that these constraints form a Lie algebra.

Manifest spacetime supersymmetry and the superstring
Journal of High Energy Physics, 2021 The algebra of spacetime supersymmetry generators in the RNS formalism for the superstring closes only up to a picture-changing operation. After adding non-minimal variables and working in the “large” Hilbert space, the algebra closes without picture ...

A Note on Toroidal Compactifications of the Type I Superstring and Other Superstring Vacuum Configurations with 16 Supercharges [PDF]
, 1997 We show that various disconnected components of the moduli space of superstring vacua with 16 supercharges admit a rationale in terms of BPS un-orientifolds, i.e.

Pinching parameters for open (super) strings
Journal of High Energy Physics, 2018 We present an approach to the parametrization of (super) Schottky space obtained by sewing together three-punctured discs with strips. Different cubic ribbon graphs classify distinct sets of pinching parameters; we show how they are mapped onto each ...

Three-loop β-functions for the superstring and heterotic string
Nuclear Physics B, 1988 Abstract The β-function for the (1,1) superstring is calculated explicitly up to three loops, using two different choices of the fermion quantum field. In both cases the bosonic contribution is exactly cancelled by the fermionic contribution. The calculation is repeated for the heterotic string and the non-vanishing β-function is shown to be ...

, 1995 This talk is divided into two parts. The first part reviews some of the duality relationships between superstring theories. These relationships are interpreted as providing evidence for the existence of a unique underlying fundamental theory.
