Description
Partial-wave analysis of experimental data provides the point
of comparison between many theoretical approaches and Nature. The
parametrization of partial waves is guided by theoretical principles of
scattering theory and effective approaches to QCD; however, data
themselves can be used to find the simplest model from a large class of
possible ones, to deliver a minimally parametrized yet accurate
description of the data. The workflow includes the combination of the Least
Absolute Shrinkage and Selection Operator (LASSO) with criteria from
information theory and cross validation. This model selection process
is illustrated in the example of low-energy pion photoproduction.
