    AnnotationWe report on an experimental and theoretical study of optical binding of polystyrene sphere pairs illuminated by retro-reflected wide Gaussian beam, so-called "tractor beam". We show that depending on configuration of particle pairs, optically bound structure in the "tractor beam" can be pushed or pulled against the beam propagation. We employ holographic video microscopy to analyse object positions in three dimensions and their time evolution. In such a way, we investigate their dynamics in dependence on the geometrical configuration that is compared with numerical simulations. We observe strong dependence of the particle pair motion on the relative distance of the particles.
