New BPS states from bosonic/heterotic duality
Journal of High Energy PhysicsIn this paper, we consider the recently proposed bosonic/heterotic duality that relates the heterotic superstrings to the noncritical bosonic string. Although the latter is nonsupersymmetric, it can be viewed as pseudo-supersymmetric in that the theory ...

Green-Schwarz and pure spinor formulations of chiral strings [PDF]
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.

A New Approach to String Theory [PDF]
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.

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.

Chiral closed strings: four massless states scattering amplitude [PDF]
Journal of High Energy Physics, 2016 A bstractWe compute the scattering amplitudes of four massless states for chiral (closed) bosonic and type II superstrings using the Kawai-Lewellen-Tye (KLT ) factorization method.

Quantization of heterotic strings in a Goedel/Anti de Sitter spacetime and chronology protection [PDF]
, 2003 We show that a Godel-like deformation of AdS3 in heterotic string theory can be realized as an exact string background. Indeed this class of solutions is obtained as an exactly marginal deformation of the worldsheet conformal field theory describing the ...

Homotopy Transfer and Effective Field Theory II: Strings and Double Field Theory
Fortschritte der Physik, Volume 70, Issue 2-3, March 2022., 2022 Abstract We continue our study of effective field theory via homotopy transfer of L∞$L_\infty$‐algebras, and apply it to tree‐level non‐Wilsonian effective actions of the kind discussed by Sen in which the modes integrated out are comparable in mass to the modes that are kept. We focus on the construction of effective actions for string states at fixed

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 ...

The anomaly that was not meant IIB
Fortschritte der Physik, Volume 70, Issue 1, January 2022., 2022 Abstract Type IIB supergravity enjoys a discrete non‐Abelian duality group, which has potential quantum anomalies. In this paper we explicitly compute these, and present the bordism group that controls them, modulo some physically motivated assumptions.

Toroidal & Orbifold Compactifications at Large D and D‐Duality
Fortschritte der Physik, Volume 70, Issue 1, January 2022., 2022 Abstract In this paper I will further investigate the spectrum of quantum gravity or string theories at large number of dimensions. We will see that volumes of certain orbifolds shrink at large D. It follows that the mass spectra of the leading Kaluza‐Klein towers and also of wrapped brane states on these orbifolds possess a non‐trivial dependence on D:
