Moduli Bounds from Spin-2 Sum Rules
Francesco Bertucci, James Bonifacio, Kurt Hinterbichler
Mirbabayi and Villadoro have provided strong numerical evidence for a universal upper bound on the mass of the lightest scalar field in gravitational Kaluza--Klein (KK) theories. T…

Bootstrapping Euclidean Lattices
Francesco Bertucci, James Bonifacio
We derive spectral identities involving the Laplace spectrum and the integrals of products of eigenfunctions on flat tori and orbifolds. Using semidefinite programming, we derive u…

Positivity Bounds on Massive Vectors
Francesco Bertucci, Johan Henriksson, Brian McPeak +3
In this paper, we explore positivity bounds for the effective field theory~(EFT) of a single weakly coupled massive vector field. The presence of both mass and spin makes the cross…
