A statistical analysis of almost 3000 star forming regions (knots) in a representative sample of 32 (U)LIRGs has been performed by means of high angular resolution ACS/HST B and I images. We present the results of the photometric characterization of these star forming regions as a function of the infrared luminosity of the systems (we have split the sample in three luminosity bins) and the interaction phase (four interaction phases have been defined). Properties such as sizes, colors and luminosities are compared with those of clusters observed in less luminous interacting galaxies and the state-of-the-art models of major mergers.
