  The study of lowest eigenmodes of the covariant Laplacian in fundamental
representation of the gauge group revealed their specific localization
properties. These may bear information on confinement of fundamental scalar
particles in SU(2) Yang-Mills vacuum. It was expected that scalar particle
eigenmodes in other representations would be localized in different physical
volumes. However simulations show strikingly different results for the adjoint
and higher (J=3/2) representations. Apart from much higher extent of
localization, we find evidence of different scaling behavior of localized
eigenmodes.
