Döring, U. Meißner, E. Oset, A. Rusetsky] We develop a scheme for the extraction of the properties of the scalar mesons f 0(600) , f 0(980) , and a 0(980) from lattice QCD data. This scheme is based on a two-channel chiral unitary approach with fully relativistic propagators in a finite volume. In order to discuss the feasibility of finding the mass and width of the scalar resonances, we analyze synthetic lattice data with a fixed error assigned, and show that the framework can be indeed used for an accurate determination of resonance pole positions in the multichannel scattering.
