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…

Towards four-pion effects in multi-hadron decays
Rajnandini Mukherjee, Maxwell T. Hansen
The rigorous treatment of four-particle intermediate and final states poses a major challenge for lattice calculations of scattering and decay amplitudes, as well as long-distance…
