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

Subleading soft theorem for multiple soft gravitons

Journal of High Energy Physics, 2017
We derive the subleading soft graviton theorem in a generic quantum theory of gravity for arbitrary number of soft external gravitons and arbitrary number of finite energy external states carrying arbitrary mass and spin.

Open Heterotic Strings

, 2005
We classify potential cosmic strings according to the topological charge measurable outside the string core. We conjecture that in string theory it is this charge that governs the stability of long strings.

Are Strings Thermostrings? [PDF]

, 1998
In the method of thermostring quantization the time evolution of point particles at finite temperature kT is described in a geometric manner. The temperature paths of particles are represented as closed (thermo)strings, which are swept surfaces in space ...

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 ...

Heterotic sigma models on T 8 and the Borcherds automorphic form Φ12

Journal of High Energy Physics, 2017
We consider the spectrum of BPS states of the heterotic sigma model with (0, 8) supersymmetry and T 8 target, as well as its second-quantized counterpart.

Loop amplitudes monodromy relations and color-kinematics duality

Journal of High Energy Physics, 2021
Color-kinematics duality is a remarkable conjectured property of gauge theory which, together with double copy, is at the heart of a wealth of new developments in scattering amplitudes.

Universal Thermal Instabilities and the High-Temperature Phase of the N=4 Superstrings [PDF]

, 1999
Using the properties of gauged N=4 supergravity, we show that it is possible to derive a universal thermal effective potential that describes all possible high-temperature instabilities of the known N=4 superstrings.

Two-loop vacuum energy for Calabi-Yau orbifold models [PDF]

, 2013
A precise evaluation of the two-loop vacuum energy is provided for certain Z_2 x Z_2 Calabi-Yau orbifold models in the Heterotic string. The evaluation is based on the recent general prescription for superstring perturbation theory in terms of ...
