Scalar mesons and tetraquarks by means of lattice QCD
Marc Wagner, Constantia Alexandrou, Jan Oliver Daldrop +5
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 iden…
Lattice investigation of the scalar mesons a_0(980) and κ using four-quark operators
Constantia Alexandrou, Jan Oliver Daldrop, Mattia Dalla Brida +4
We carry out an exploratory study of the isospin one a0(980) and the isospin one-half kappa scalar mesons using Nf=2+1+1 Wilson twisted mass fermions at one lattice spacing. The va…
Lattice investigation of the tetraquark candidates a0(980) and kappa
Jan Oliver Daldrop, Constantia Alexandrou, Mattia Dalla Brida +4
It is a long discussed issue whether light scalar mesons have sizeable four-quark components. We present an exploratory study of this question using N_f=2+1+1 twisted mass lattice…
