Description

In this study, we present the potential of discovering new physics associated with a new charged vector boson decaying into heavy neutral leptons, using ultraperipheral lead ion collisions. We identify the optimal kinematic cuts that increase the statistical significance, which would allow us to detect signals of the possible existence of these particles, as predicted by the Vector Scotogenic Model. In addition, we calculate the necessary luminosity that the ATLAS experiment should reach in this type of collisions to achieve a statistical significance of 2$\sigma$ and 5$\sigma$ related to the existence of this new physics.
