Hadron dynamics on the lattice (A02)

• Subject Area: Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
• Term: since 2012
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 196253076

In this project we will continue to investigate hadron dynamics from first principles using lattice QCD. As a basis we have successfully generated ensembles with dynamical light, strange and charm quarks all tuned to their physical mass values. For the next CRC110 cycle we will continue to generate such ensembles so that we have better control over lattice artifacts and finite size effects. Our recent studies of two-meson systems show that one of the main systematic uncertainties comes from the extrapolation to the physical point. Thus, with our physical point lattices generated from the previous CRC cycle, we will extend our investigation of two meson systems directly to the physical point, essentially removing this systematic uncertainty. Further, we will consider the pion-nucleon system, baryon-baryon interactions, three-particle systems and exotic states.
