      abstract     = {Simulating the kappa(800) on the lattice is a challenging
                      task that starts to become feasible due to the rapid
                      progress in recent-years lattice QCD calculations. As the
                      resonance is broad, special attention to finite-volume
                      effects has to be paid, because no sharp resonance signal as
                      from avoided level crossing can be expected. In the present
                      article, we investigate the finite volume effects in the
                      framework of unitarized chiral perturbation theory using
                      next-to-leading order terms. After a fit to meson-meson
                      partial wave data, lattice levels for piK scattering are
                      predicted. In addition, levels are shown for the quantum
                      numbers in which the sigma(600), $f_0(980),$ $a_0(980),$
                      phi(1020), K*(892), and rho(770) appear, as well as the
                      repulsive channels. Methods to extract the kappa(800) signal
                      from the lattice spectrum are presented. Using pseudo-data,
                      we estimate the precision that lattice data should have to
                      allow for a clear-cut extraction of this resonance. To put
                      the results into context, in particular the required high
                      precision on the lattice data, the sigma(600), the P-wave
                      resonances K*(892) and rho(770), and the repulsive piK, pipi
                      phases are analyzed as well.},
