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…
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…
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…
Collider Signatures of Flavorful Higgs Bosons
Wolfgang Altmannshofer, Joshua Eby, Stefania Gori +3
Motivated by our limited knowledge of the Higgs couplings to first two generation fermions, we analyze the collider phenomenology of a class of two Higgs doublet models (2HDMs) wit…
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…
Group Momentum Space and Hopf Algebra Symmetries of Point Particles Coupled to 2+1 Gravity
Michele Arzano, Danilo Latini, Matteo Lotito
We present an in-depth investigation of the momentum space describing point particles coupled to Einstein gravity in three space-time dimensions. We introd…
