Amid all candidates of physics beyond the Standard Model, string theory provides a unique
proposal for incorporating gauge and gravitational interactions. In string theory, a four …

Besides the familiar D-branes, string theory contains a vast number of other non-perturbative
objects. While a complete classification is lacking, many of these objects are related to each …

A bstract Motivated by principles from the Swampland program, which characterize
requirements for a consistent UV completion of quantum gravity, combined with …

We give a brief overview of the string landscape and techniques used to construct string
compactifications. We then explain how this motivates the notion of the swampland and …

We use F‐theory to classify possibly all six‐dimensional superconformal field theories
(SCFTs). This involves a two step process: We first classify all possible tensor branches …

A bstract A single M5-brane probing G, an ADE-type singularity, leads to a system which has
G× G global symmetry and can be viewed as “bifundamental”(G, G) matter. For the AN …

Motivated by the recent CDF measurement of the W-boson mass, we study string-based
particle physics models which can accommodate this deviation from the Standard Model …

Abstract Extra``hidden''U (1) gauge factors are a generic feature of string theory that is of
particular phenomenological interest. They can kinetically mix with the Standard Model …

The real world as we know it happens at energies well below the Planck scale, so it is very
well described by effective field theory. There is a continuous infinity of consistent effective …

A bstract Applying the Ashok-Denef-Douglas estimation method to elliptic Calabi-Yau
fourfolds suggests that a single elliptic fourfold\({\mathrm {\mathcal {M}}} _ {\max}\) gives rise …
