Connecting the ambitwistor and the sectorized heterotic strings
Journal of High Energy Physics, 2017 The sectorized description of the (chiral) heterotic string using pure spinors has been misleadingly viewed as an infinite tension string. One evidence for this fact comes from the tree level 3-point graviton amplitude, which we show to contain the usual

Confinement from distance in metric space and its relation to cosmological constant
Journal of High Energy PhysicsWe 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

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.

Towards massive field-theory amplitudes from the cohomology of pure spinor superspace
Journal of High Energy PhysicsBy 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

String field theoryะ Time evolution and T-duality [PDF]
, 2005 The time evolution operator of quantum field theory (Schrödinger functional) can be written in terms of particles moving on S(^1)/Z(_2-). By deriving the 'gluing property’ which joins two propagators across fixed time surfaces, we show that the Feynman ...

Massless representation of massive superfields and tree amplitudes with the pure spinor formalism
Journal of High Energy PhysicsWe 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 ...

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 ...

Phase transitions as the origin of large scale structure in the universe [PDF]
, 1988 A review of the formation of large scale structure through gravitational growth of primordial perturbations is given. This is followed by a discussion of how symmetry breaking phase transitions in the early universe might have produced the required ...
