Composite dark matter hides stable heavy charged particles in neutral atom-like states. Physical examples of such stable particles are given by U-quark of 4th generation from heterotic string phenomenology, by tera-particles of S.L.Glashow's Sinister model and by AC-leptons from models, based on almost commutative geometry. In the early Universe formation of composite dark matter is accompanied by formation of various fractions of exotic matter. These fractions and their transformations are severely constrained by experimental data. In the context of this approach accelerator and cosmic ray search for new stable quarks and leptons acquires the significance of experimentum crucis for charged components of composite dark matter.
