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

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 ...

Non-critical Heterotic Superstrings in Various Dimensions

, 2006
We construct heterotic string theories on spacetimes of the form R^{d-1,1} times N=2 linear dilaton, where d=6,4,2,0. There are two lines of supersymmetric theories descending from the two supersymmetric ten-dimensional heterotic theories.

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 ...

Arguments for F-theory [PDF]

, 2005
After a brief review of string and $M$-Theory we point out some deficiencies. Partly to cure them, we present several arguments for ``$F$-Theory'', enlarging spacetime to $(2, 10)$ signature, following the original suggestion of C. Vafa.

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.

The Bosonic Ancestor of Closed and Open Fermionic Strings [PDF]

, 2002
We review the emergence of the ten-dimensional fermionic closed string theories from subspaces of the Hilbert space of the 26-dimensional bosonic closed string theory compactified on an $E_8\times SO(16)$ lattice.
