Using Evolutionary Algorithms to Extract Field Theory Mass Spectra

Presenter: Robert Petry — University of Regina

G.M. von Hippel, Randy Lewis, and Robert G. Petry

The spectrum of masses from a lattice QCD simulation may be found by fitting exponential functions to correlators of operators possessing the quantum numbers of the particle of interest. The ability of evolutionary algorithms to find globally optimized solutions containing a variable number of states across multiple data sets is exploited to provide a promising solution to this problem.
