Abstract
New order parameters involving ratios of gauge invariant correlation functions for distinguishing different phases - confined/screened or free charges - in systems with lattice gauge fields coupled to matter fields have been proposed by Fredenhagen and Marcu and by Bricmont and Fröhlich. Our Monte Carlo analysis of those quantities for an SU(2) gauge field coupled to scalar matter fields in the fundamental representation supports the theoretically expected behaviour. Also a new mass parameter determining the exponential decay of two-point functions is observed.
