String breaking by light and strange quarks in QCD
The energy spectrum of a system containing a static quark anti-quark pair is computed for a wide range of source separations using lattice QCD with Nf=2+1 dynamical flavours. By employing a variational method with a basis including operators resembling both the gluon string and systems of two separa...
