Scalar mesons in a finite volume

Michael Lage (Bonn)

Using effective field theory methods, we discuss the extraction of the mass and width of the scalar mesons f₀(980) and a₀(980) from the finite-volume spectrum in lattice QCD. In particular, it is argued that the nature of these states can be studied by invoking twisted boundary conditions, as well as investigating the quark mass dependence of the spectrum.
