Numerical Stochastic Perturbation Theory in the Schrödinger Functional
Michele Brambilla, Mattia Dalla Brida, Francesco Di Renzo +2
The Schrödinger functional (SF) is a powerful and widely used tool for the treatment of a variety of problems in renormalization and related areas. Albeit offering many conceptual…
Investigation of light and heavy tetraquark candidates using lattice QCD
Marc Wagner, Abdou Abdel-Rehim, Constantia Alexandrou +5
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 . First step…
Study of the a_0(980) on the lattice
Marc Wagner, Abdou Abdel-Rehim, Constantia Alexandrou +5
We present lattice results for the a_0(980) state using a variational approach with a variety of creation operators: quark-antiquark, mesonic molecule, diquark-antidiquark as well…
Scalar mesons and tetraquarks from twisted mass lattice QCD
Marc Wagner, Constantia Alexandrou, Jan Oliver Daldrop +5
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…
