Understand

We study the light scalar mesons a_0(980) and kappa using N_f = 2+1+1 flavor lattice QCD.

In order to probe the internal structure of these scalar mesons, and in particular to identify, whether a sizeable tetraquark component is present, we use a large set of operators, including diquark-antidiquark, mesonic molecule and two-meson operators.
The inclusion of disconnected diagrams, which are technically rather challenging, but which would allow us to extend our work to e.g.
the f_0(980) meson, is introduced and discussed.
