Context. The ESO public survey VISTA Variables in the Via Lactea (VVV) has contributed with deep multi-epoch photometry of the Galactic bulge and the adjacent part of the disk over 526 sq. deg. More than a hundred cluster candidates have been reported thanks to this survey.
Aims. We present the fifth article in a series of papers focused on young and massive clusters discovered in the VVV survey. In this paper, we present the physical characterization of five clusters with a spectroscopically confirmed OB-type stellar population.
Methods. To characterize the clusters, we used near-infrared photometry (J, H, and Ks) from the VVV survey and near-infrared K-band spectroscopy from ISAAC at VLT, following the methodology presented in the previous articles of the series.
Results. All clusters in our sample are very young (ages between 1-20Myr), and their total mass are between (1.07+0.40-0.30)x10²M☉ and (4.17^+4.15_–2.08)x10³M☉. We observed a relation between the clusters total mass Mecl and the mass of their most massive stellar member mmax, for clusters with an age <10Myr.
