Strongly-coupled black holes (are not) at weak coupling
Ben Heidenreich, Matteo Lotito
The authors prove rigorous bounds on the scalar‑field (moduli) excursion outside a spherically symmetric charged black hole, showing it cannot exceed π/(2√k_N), and use this result…
The weak gravity conjecture in perturbative strings
Matteo Lotito
In this note we give a summary of [arXiv:2401.14449] in which we proposed a proof of the weak gravity conjecture in perturbative string theory. While the WGC is well established, c…
UV/IR relations from the worldsheet
Christian Aoufia, Ivano Basile, Giorgio Leone +1
We derive universal scaling relations for the low-energy effective action of string theory, connecting the vacuum energy and gauge couplings to higher-derivative Wilson coefficient…
Twists of superconformal algebras
Chris Elliott, Owen Gwilliam, Matteo Lotito
We take first steps toward a theory of ``conformal twists'' for superconformal field theories in dimension 3 to 6, extending the well-known analysis of twists for supersymmetric th…
Special Kähler geometries of superYang-Mills
Philip C. Argyres, Antoine Bourget, Julius F. Grimminger +2
The low energy effective theory on the moduli space of vacua of 4d superYang-Mills (sYM) theory defines a special Kähler geometry. For simple sYM gauge algebras, , w…
Proving the Weak Gravity Conjecture in Perturbative String Theory, Part I: The Bosonic String
Ben Heidenreich, Matteo Lotito
We present a complete proof of the Weak Gravity Conjecture in any perturbative bosonic string theory in spacetime dimension . Our proof works by relating the black hole extr…
