Method to study complex systems of mesons in lattice QCD
Abstract
Correlation functions involving many hadrons allow finite density systems to be explored with Lattice QCD. Recently, systems with up to 12 $$\pi^+$$'s or $K^+$'s have been studied to determine the the $3$$$\pi^+$$ and $3$$K^+$ interactions and the corresponding chemical potential has been determined as a function of density in each case. We derive recursion relations between correlation functions that allow us to extend this work to systems of arbitrary numbers of mesons and to systems containing arbitrary different types of mesons such as $$\pi^+$$'s, $K^+$'s, $D^0$'s and $B^+$'s. These relations allow for the study of finitedensity systems in arbitrary volumes, and the study of highdensity systems. Systems comprised of up to N=12 m mesons can be explored with Lattice QCD calculations utilizing $m$ different sources for the quark propagators. As the recursion relations require only a small, Nindependent, number of operations to derive the N+1 meson contractions from the N meson contractions, they are compuationally feasible.
