Higher order quantization conditions for two-body scattering with spin
Lucas Chandler, Frank X. Lee, Andrei Alexandru
We examine the Lüscher quantization condition to high order for the scattering of a spinless particle and a spin-1/2 particle in a periodic box. First, we derive the quantization c…
Coupled-channel approach to isotensor scattering from lattice QCD
Yuchuan Feng, Chris Culver, Michael Döring +3
The quest to understand three-body dynamics from first-principle QCD includes the study of non-resonant and resonant systems. The isospin system is of particular interest hav…
Neutral pion polarizabilities from four-point functions in lattice QCD
Frank X. Lee, Walter Wilcox, Andrei Alexandru +2
We report a proof-of-principle lattice QCD simulation of the electric and magnetic polarizabilities for a neutral pion in the four-point function method. The results are based on t…
Higher order finite volume quantization conditions for two spinless particles
Frank X. Lee, Andrei Alexandru, Ruairí Brett
Lattice QCD calculations of scattering phaseshifts and resonance parameters in the two-body sector are becoming precision studies. Early calculations employed Lüscher's formula for…
