Progress in three-particle scattering from LQCD
Raúl A. Briceño, Maxwell T. Hansen, Stephen R. Sharpe
We present the status of our formalism for extracting three-particle scattering observables from lattice QCD (LQCD). The method relies on relating the discrete finite-volume spectr…
On the effect of excited states in lattice calculations of the nucleon axial charge
Maxwell T. Hansen, Harvey B. Meyer
Excited-state contamination is one of the dominant uncertainties in lattice calculations of the nucleon axial-charge, . Recently published results in leading-order chiral pert…
Progress on the three-particle quantization condition
Raul A. Briceno, Maxwell T. Hansen, Stephen R. Sharpe
We report progress on extending the relativistic model-independent quantization condition for three particles, derived previously by two of us, to a broader class of theories, as w…
Applying the relativistic quantization condition to a three-particle bound state in a periodic box
Maxwell T. Hansen, Stephen R. Sharpe
Using our recently developed relativistic three-particle quantization condition, we study the finite-volume energy shift of a spin-zero three-particle bound state. We reproduce the…
Threshold expansion of the three-particle quantization condition
Maxwell T. Hansen, Stephen R. Sharpe
We recently derived a quantization condition for the energy of three relativistic particles in a cubic box. Here we use this condition to study the energy level closest to the thre…
