Multi-hadron systems in lattice QCD
Abstract
Lattice QCD is a well established tool for studying the low energy dynamics of
QCD. Precise results with fully controlled uncertainties are available for many
single hadron properties and lattice QCD has become a integral part of modern
particle physics. In the last few years the first realistic calculations in
the two hadron sector have also appeared (although not yet with the same level
of systematic control of uncertainties as in the single hadron case)
stimulating the interest of the nuclear physics community as well. To become a
central part of nuclear physics, lattice QCD must confront the many hadron
systems that define nuclear physics.
Recently, the first steps have been taken in this direction by the NPLQCD
collaboration who have performed a series of numerically studies of systems of
up to twelve pions and/or kaons and up to three baryons. I will review this
work and outline the future prospects for lattice QCD in nuclear physics.
