Higher-derivative heterotic Double Field Theory and classical double copy

Journal of High Energy Physics, 2021
The generalized Kerr-Schild ansatz (GKSA) is a powerful tool for constructing exact solutions in Double Field Theory (DFT). In this paper we focus in the heterotic formulation of DFT, considering up to four-derivative terms in the action principle, while

Dual String Pairs With N=1 And N=2 Supersymmetry In Four Dimensions [PDF]

, 1995
Based on a simple adiabatic argument and by considering the heterotic string counterpart of certain symmetries of Type II superstrings such as $(-1)^{F_L}$ and orientation reversal, we construct orbifold candidates for dual pairs of heterotic and Type II

Two-point string amplitudes

Journal of High Energy Physics, 2019
We show that the two-point tree level amplitude in string theory in flat space is given by the standard free particle expression.

Dilaton incoming vertices of the closed superstring and the heterotic string

Physics Letters B, 1990
Abstract BRST- and conformally-invariant incoming vertices for the dilaton are constructed in the closed superstring and the heterotic string theories. The BRST-invariant (0, 0) conformal field corresponding to the dilaton is determined up to a BRST cohomology transformation.

Random Walks in Rindler Spacetime and String Theory at the Tip of the Cigar [PDF]

, 2014
In this paper, we discuss Rindler space string thermodynamics from a thermal scalar point of view as an explicit example of the results obtained in JHEP 1402 (2014) 127.

Worldsheet description of a massive type IIA superstring in 10D

Journal of High Energy Physics, 2023
We construct, following [1, 2], a massive M2-brane (supermembrane) as the limit of a genus two M2-brane that becomes a twice punctured Riemann surface with particular boundary conditions on the fields defined on the punctures.

On the equivalence between SRS and PCO formulations of superstring perturbation theory

Journal of High Energy Physics, 2023
We establish the equivalence between two formulations of superstring perturbation theory, one based on integration over the supermoduli space of super Riemann surfaces (SRS), the other based on integration over the bosonic moduli space with insertions of

Electric/magnetic duality and its stringy origins [PDF]

, 1995
We review electric/magnetic duality in $N=4$ (and certain $N=2$) globally supersymmetric gauge theories and show how this duality, which relates strong to weak coupling, follows as a consequence of a string/string duality.

Topological amplitude computations using the pure spinor formalism

Journal of High Energy Physics, 2019
After constructing a simplified four-dimensional version of the b ghost, topological multiloop amplitudes in type II superstring theory compactified on a six-dimensional orbifold are computed using the non-minimal pure spinor formalism. These pure spinor

Massive theta lifts

Journal of High Energy Physics, 2023
We use Poincaré series for massive Maass-Jacobi forms to define a “massive theta lift”, and apply it to the examples of the constant function and the modular invariant j-function, with the Siegel-Narain theta function as integration kernel.
