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…
Isotensor scattering with a resonant subsystem from QCD
Raúl A. Briceño, Maxwell T. Hansen, Andrew W. Jackura +2
This work presents a lattice quantum chromodynamics (QCD) determination of scattering amplitudes for the isospin-2 channel with angular momentum and parity .…
Finite-volume formalism for at maximal isospin
Maxwell T. Hansen, Fernando Romero-López, Stephen R. Sharpe
We extend the relativistic field theoretic finite-volume formalism to scattering states at maximal isospin, . As in previous work using the relativistic field theor…
Implementing the finite-volume three-pion scattering formalism across all non-maximal isospins
Athari Alotaibi, Maxwell T. Hansen, Raúl A. Briceño
We present a numerical exploration of the relativistic-field-theory (RFT) formalism for three pions with all possible values of non-maximal isospin, , and .…
Implementing the RFT finite-volume formalism for three pions across all non-maximal isospins
Athari Alotaibi, Maxwell T. Hansen
We present a numerical investigation of the relativistic-field-theoretic (RFT) formalism, used to predict the discrete energy spectrum of three pions in a finite volume. Applying t…
