1. Scalar mesons and tetraquarks from twisted mass lattice QCD

Prof. Marc Wagner (Goethe University Frankfurt)

We study the light scalar mesons a_0(980) and \kappa using N_f = 2+1+1 flavor twisted mass 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. We find that the low-lying states...
