Super star clusters (SSCs) are typically found in interacting galaxies andtrace an extreme form of star-formation. We present a K-band study of SSCcandidates in a sample of local luminous infrared galaxies (LIRGs) using twoadaptive optics instruments (VLT/NACO and Gemini/ALTAIR/NIRI). In addition tofacilitating SSC detections in obscured environments, this work introduces SSCstudies in hosts with higher star-formation rates (SFRs) than most previousstudies. We find that the luminosity functions (LFs) of the clusters arereasonably well-fitted by a single power-law with the values of the index\alpha ranging between 1.5 to 2.4 with an average value of \alpha ~ 1.9. Thisvalue appears to be less steep than the average \alpha ~ 2.2 in normal spiralgalaxies. Due to the host galaxy distances involved (median $D_L$ ~ 70 Mpc)blending effects have to be taken into account, and are investigated usingMonte Carlo simulations of blending effects for LFs and a photometric SSCanalysis of the well-studied Antennae system which is artificially redshiftedto distances of our sample. While blending tends to flatten LFs our analysesshow that \Delta \alpha is less than ~ 0.1 in our sample. The simulations alsoshow that in the luminosity range, $M_K < -13$, considered in this work theextracted SSC luminosities are generally dominated by a single dominant starcluster rather than several knots of SF. We present resolution- anddistance-dependent SSC surface density confusion limits and show how blendingrates and aperture sizes affect the LFs. The smallest possible apertures shouldbe used in crowded regions.
