Hadron properties from lattice QCD
(2014)We discuss the status of current dyanmical lattice QCD simulations in connection to the emerging results on the low-lying baryon spectrum, excited states of the nucleon and the investigation of the structure of scalar ...

Investigation of light and heavy tetraquark candidates using lattice QCD
(2014)We review the status of an ongoing long-term lattice investigation of the spectrum and structure of tetraquark candidates. We focus on the light scalar meson a0(980). First steps regarding the study of a possibly existing ...

Scalar mesons and tetraquarks by means of lattice QCD
(2012)We study the light scalar mesons a0(980) and κ using Nf = 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 ...

Scalar mesons and tetraquarks from twisted mass lattice QCD
(2013)We study light scalar mesons with particular focus on the a 0(980) using lattice QCD with 2+1+1 dynamical quark flavors. To investigate the structure of these scalar mesons and to identify, whether a sizeable tetraquark ...

Using a new analysis method to extract excited states in the scalar meson sector
(Proceedings of Science (PoS), 2016)We explore a method to extract energy eigenstates, called Athens Model Independent Analysis Scheme (AMIAS), which is an alternative to solving standard Generalized Eigenvalue Problems (GEVP). The method is based on ...
