Evolutionary Fitting Methods for Mass Spectra in Lattice Field Theory — •Georg von Hippel1, Randy Lewis2, and Rob Petry2 — 1DESY Zeuthen, D-15738 Zeuthen — 2University of Regina, Regina (Saskatchewan), Kanada
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 particles 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 the problem of finding these fits.
