  HADRON-HADRON SCATTERING LENGTHS FROM LATTICE QCD 

 

 ABSTRACT

 

A steady stream of developments in Lattice QCD (Quantum Chromodynamics) have made it possible today to  begin  to address the question of how nuclear physics emerges from the underlying theory of strong interactions. Central role in this understanding play both the effective field theory description of nuclear  forces and the ability to perform accurate non-perturbative calculations in low energy QCD.
Here I present some recent results on hadronic scattering lengths from lattice QCD. In addition, I will address the numerical problems we encounter in such calculations and will discuss possible algorithmic improvements.
