Title: Many-body Systems in QCD

Abstract:
Multi-hadron systems are of great interest in many areas of physics, 
from low energy scattering experiments to neutron stars. In this 
seminar, I will discuss such systems from the point of view of lattice 
QCD. While QCD calculations of single hadron properties are at a 
relatively mature stage, multi-hadron states are only beginning to be 
explored. I will describe recent progress in calculations of systems of 
up to twelve mesons. These calculations have allowed us to determine 
both the two-and three-body interactions between pions and kaons for 
the first time.
