Strongly-coupled black holes (are not) at weak coupling
Ben Heidenreich, Matteo Lotito
We prove sharp bounds on the moduli space excursion that is possible outside the event horizon of a spherically symmetric charged black hole. In regions where the black hole charge…
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…
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, , we…
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…
Vertex algebra of extended operators in 4d N=2 superconformal field theories
Philip C. Argyres, Matteo Lotito, Mitch Weaver
We construct a class of extended operators in the cohomology of a pair of twisted Schur supercharges of 4d N=2 SCFTs. The extended operators are constructed from the local operator…
Deconfining SCFTs, or the Art of Brane Bending
Iñaki García Etxebarria, Ben Heidenreich, Matteo Lotito +1
We introduce a systematic approach to constructing Lagrangians for a class of interacting SCFTs. We analyse in detail the simplest case of the const…
Flavor symmetries and the topology of special Kähler structures at rank 1
Philip C. Argyres, Matteo Lotito
We propose a method for determining the flavor charge lattice of the continuous flavor symmetry of rank-1 4d N = 2 superconformal field theories (SCFTs) and IR free gauge theories…
Geometric constraints on the space of N=2 SCFTs III: enhanced Coulomb branches and central charges
Philp Argyres, Matteo Lotito, Yongchao Lü +1
This is the third in a series of three papers on the systematic analysis of rank 1 four dimensional SCFTs. In the first two papers we developed and carried out a st…
Expanding the landscape of =2 rank 1 SCFTs
Philip C. Argyres, Matteo Lotito, Yongchao Lü +1
We refine our previous proposal for systematically classifying 4d rank-1 SCFTs by constructing their possible Coulomb branch geometries. Four new recently discussed…
Geometric constraints on the space of N=2 SCFTs II: Construction of special Kähler geometries and RG flows
Philip C. Argyres, Matteo Lotito, Yongchao Lü +1
This is the second in a series of three papers on systematic analysis of rank 1 Coulomb branch geometries of four dimensional =2 SCFTs. In the first paper we developed…
Geometric constraints on the space of N=2 SCFTs I: physical constraints on relevant deformations
Philip Argyres, Matteo Lotito, Yongchao Lü +1
We initiate a systematic study of four dimensional superconformal field theories (SCFTs) based on the analysis of their Coulomb branch geometries. Because these SCF…
