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 …

A bstract Asymptotically massless towers of species are ubiquitous in the string landscape
when infinite-distance limits are approached. Due to the remarkable properties of string …

String and 5-brane junctions are shown to succinctly classify all known 8D N= 1 string
vacua. This requires an extension of the description for ordinary [p, q]-7-branes to …

A bstract The space of 6D supergravities with minimal supersymmetry is greatly constrained
by anomaly cancellation. Nevertheless, a large number of models satisfy all low-energy …

We view and provide further evidence for a number of swampland criteria, including the
weak gravity conjecture, distance conjecture and bounds on the finiteness of the quantum …

A bstract The landscape of six-dimensional supergravities is dramatically constrained by the
cancellation of gauge and gravitational anomalies, but the full extent of its implications has …

A bstract We describe three previously unnoticed components of the moduli space of
minimally supersymmetric string theories in d≥ 7, describing in some detail their spectrum …

A bstract We propose quantum gravitational constraints on effective four-dimensional
theories with\(\mathcal {N}\)= 1 supersymmetry. These Swampland constraints arise by …

A bstract It has been proposed that cobordism and K-theory groups, which can be
mathematically related in certain cases, are physically associated to generalised higher …

A bstract We extend the analysis of [9] to the 6d (1, 0) SCFTs known as massive E-string
theories, which can be engineered in massive Type IIA with 8− n 0< 8 D8-branes close to an …
