Finite-volume effects on smeared spectral densities
Francesca A. Bresciani, Mattia Bruno, Maxwell T. Hansen
Using two distinct approaches, we derive a universal expression for the leading finite-volume effects of the smeared vector-vector spectral density (proportional to the smeared had…

Spectral densities from Euclidean-time lattice correlation functions
Matteo Saccardi, Mattia Bruno, Leonardo Giusti
In quantum field theories, spectral densities are directly related to relevant physical observables. In Lattice QCD, their non-perturbative extraction from first principles require…

Thermal evolution of dark matter and gravitational-wave production in the early universe from a symplectic glueball model
Mattia Bruno, Niccolò Forzano, Marco Panero +1
The hypothesis that dark matter could be a bound state of a strongly coupled non-Abelian gauge theory is theoretically appealing and has a variety of interesting phenomenological i…
