Description
L\"{u} scher method for two-particle scattering is a critical tool for
connecting finite-volume spectrum to infinite-volume scattering phaseshifts.
We numerically validate the quantization conditions up to partial waves l=4.
Various setups used in practice are considered: cubic or elongated lattices, rest or moving frames, unequal or equal masses, and integer or half-integer total angular momentum.
