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…
Properties of pseudoscalar flavour-singlet mesons from 2+1+1 twisted mass lattice QCD
Krzysztof Cichy, Vincent Drach, Elena Garcia-Ramos +5
We study properties of pseudoscalar flavour-singlet mesons from Wilson twisted mass lattice QCD with Nf=2+1+1 dynamical quark flavors. Results for masses are presented at three val…
Quark mass and chiral condensate from the Wilson twisted mass lattice quark propagator
Florian Burger, Vittorio Lubicz, Michael Müller-Preussker +2
In this work, we report about the determination of nonperturbative OPE parameters from fits of continuum perturbation theory to the Landau gauge quark propagator. The propagators a…
η and η' mesons from Nf=2+1+1 twisted mass lattice QCD
K. Ottnad, C. Michael, S. Reker +1
We determine mass and mixing angles of eta and eta' states using Nf=2+1+1 Wilson twisted mass lattice QCD. We describe how those flavour singlet states need to be treated in this l…
