Abstract:

Hadron interactions in lattice QCD: Non-perturbative studies on interactions between composite particles

After a brief introduction to theoretical and numerical aspects of lattice Quantum ChromoDynamics (QCD), I explain our methodology, called the HAL QCD potential method, which has been proposed primarily to extract a nuclear potential, a potential between proton and neutron, from the fundamental interaction, QCD. Since proton and neutron are composite particles of quarks and gluons, it is rather nontrivial to define a potential between them. I show how we have solved this difficulty and present some results on the nuclear potential. I also report on the lates application of the HAL QCD method to various types of interactions between hadrons including comparisons with experimental data.
