The VVV near-infrared Survey has performed time-domain observations in the Ks-band for 6 years and provides an atlas of 562 sq. deg. of the sky in 5 wavebands (ZYJHKs). The VVV data outcome offer a unique dataset to map the stellar populations deeply embedded into highly obscured regions. The recent discoveryof a significant number of globular clusters (GCs) distributed in different regions of our Galaxy, achieved by using the VVV data, evidence the incompleteness (scantiness ?) of the known GC population. The new discoveries are important and have statistic impact on the globally known properties of these objects. In this presentation, we show our latest results of the analysis of a selected sample from the newly discovered low luminosity GCs in the most obscured regions of our Galaxy. We also discuss the requirements or tests which were taken into account to confirm their real GC nature (or their nature asGCs).
