Heterotic complex structure moduli stabilization for elliptically fibered Calabi-Yau manifolds

Journal of High Energy Physics, 2021
Holomorphicity of vector bundles can stabilize complex structure moduli of a Calabi-Yau threefold in N = 1 supersymmetric heterotic compactifications. In principle, the Atiyah class determines the stabilized moduli.

Locality and causality properties of light cone string field theory [PDF]

, 2004
The recent discovery of a new maximally supersymmetric background for the type IIB superstring theory has revived the interest in light cone string field theory.

Confinement from distance in metric space and its relation to cosmological constant

Journal of High Energy Physics
We argue that, in a theory of quantum gravity, the gauge coupling and the confinement scale of a gauge theory are related to distance in the space of metric configurations, and in turn to the cosmological constant. To support the argument, we compute the

Bosonic construction of superstring theory and related topics [PDF]

, 2002
This thesis splits into two parts. In the first part we introduce a bosonic construction of the ten-dimensional fermionic theories. This construction relies on a consistent truncation procedure which can produce fermions out of bosons. We illustrate this

Towards massive field-theory amplitudes from the cohomology of pure spinor superspace

Journal of High Energy Physics
By analogy with the formula for the massless string disk amplitudes, we define massive field-theory tree amplitudes and conjecture that the BRST cohomology structure of pure spinor superspace fixes their form. We give evidence by deriving the pure spinor

State counting on fibered CY 3-folds and the non-Abelian weak gravity conjecture

Journal of High Energy Physics, 2021
We extend the dictionary between the BPS spectrum of Heterotic strings and the one of F-/M-theory compactifications on K3 fibered Calabi-Yau 3-folds to cases with higher rank non-Abelian gauge groups and in particular to dual pairs between Heterotic CHL ...

Massless representation of massive superfields and tree amplitudes with the pure spinor formalism

Journal of High Energy Physics
We construct the unintegrated vertex operator at the first mass level of the open superstring from the OPE of massless vertices. Using BRST cohomology manipulations, the tree amplitude of two massless and one massive state is rewritten in terms of the ...

Eigenvalue equation for the modular graph C a,b,c,d

Journal of High Energy Physics, 2019
The modular graph C a,b,c,d on the torus is a three loop planar graph in which two of the vertices have coordination number four, while the others have coordination number two. We obtain an eigenvalue equation satisfied by C a,b,c,d for generic values of

Completing R 4 using O(d, d)

Journal of High Energy Physics, 2022
The tree-level string effective action is known to contain quartic Riemann terms with coefficient ζ(3)α′3. In the case of the type II string this is the first α′ correction.
