Supernovae represent the explosive death of a star. There is a small group of core-collapse supernovae whose peak luminosity in the light curve is so high that it cannot be explained by conventional models. Therefore, it is necessary to consider alternative boosting mechanisms to understand their origin.  In this talk, I will present the characterization of the largest sample of hydrogen-rich superluminous supernovae (SLSN II) available to date. I will discuss the possible mechanisms responsible for the observed features and the minimum requirements needed to conduct similar analyses using data from the Legacy Survey of Space and Time (LSST) of the Vera C. Rubin Observatory.
