Towards AdS distances in string theory by Yixuan Li, Eran Palti, Nicolò Petri

“…This metric is negative, making the distance ill-defined, a property relating to the famous conformal factor problem of quantum gravity. However, in string theory, variations of the AdS conformal factor are accompanied by variations of the internal dimensions and of the background flux. …”

A New Approach to String Theory by Albert Schwarz

“…We apply this construction to string theory. We find that scattering amplitudes in critical bosonic closed string theory can be expressed in terms of physical quantities of the new type. …”

Starobinsky inflation from string theory? by Max Brinkmann, Michele Cicoli, Pietro Zito

“…Previous efforts to derive Starobinsky inflation from string theory have been based on the derivation of higher derivative curvature terms from the low-energy limit of ten-dimensional string theory. …”

CP violation from string theory by Hans Peter Nilles, Michael Ratz, Andreas Trautner, Patrick K.S. Vaudrevange

“…We identify a natural way to embed CP symmetry and its violation in string theory. The CP symmetry of the low energy effective theory is broken by the presence of heavy string modes. …”

Embedding Unimodular Gravity in string theory by Luis J. Garay, Gerardo García-Moreno

“…We restrict ourselves to the unoriented bosonic string theory in critical dimension for the sake of simplicity, although we argue that no differences are expected for other string theories. …”

Non-relativistic heterotic string theory by Eric A. Bergshoeff, Luca Romano

“…Abstract In this work we consider heterotic-gravity as the low-energy approximation to heterotic string theory. We define a consistent non-relativistic limit of heterotic gravity that includes the Yang-Mills Chern-Simons term. …”

Quantum no-scale regimes in string theory by Thibaut Coudarchet, Claude Fleming, Hervé Partouche

“…We show that in generic no-scale models in string theory, the flat, expanding cosmological evolutions found at the quantum level can be attracted to a “quantum no-scale regime”, where the no-scale structure is restored asymptotically. …”

T-duality equivalences beyond string theory by José D. Edelstein, Konstantinos Sfetsos, J. Anibal Sierra-Garcia, Alejandro Vilar López

“…This further supports the idea put forward in our previous work that T-duality might provide physical equivalences beyond the realm of string theory.…”

On codimension-one vacua and string theory by Salvatore Raucci

“…We investigate codimension-one vacua arising from low energy effective actions inspired by string theory, with an eye to their consistency when localized sources are allowed in the equations of motion. …”

Comparing double string theory actions by De Angelis, L, Gionti, G, Marotta, R, Pezzella, F

“…Aimed to a deeper comprehension of a manifestly T-dual invariant formulation of string theory, in this paper a detailed comparison between the non-covariant action proposed by Tseytlin and the covariant one proposed by Hull is done. …”
