Kaon-kaon scattering at maximal isospin from twisted mass lattice QCD
Christopher Helmes, Christian Jost, Bastian Knippschild +4
We present results for the interaction of two kaons at maximal isospin. The calculation is based on 2+1+1 flavour gauge configurations generated by the ETM Collaboration (ETMC) fea…

Pi-Pi Scattering with Nf=2+1+1 Twisted Mass Fermions
Christopher Helmes, Christian Jost, Bastian Knippschild +3
Pi-Pi scattering is investigated for the first time for Nf=2+1+1 dynamical quark flavours using Wilson twisted mass fermions. Lüscher's finite size method is used to relate energy…
