Searching for New Physics with multilepton events at PADME
Gabriele Martelli, Paolo Ciafaloni, Mauro Raggi

TL;DR
The paper discusses the potential of the PADME experiment to discover or constrain new physics involving dark sector particles, specifically through multilepton events resulting from dark Higgs and dark photon production.
Contribution
It introduces the possibility of detecting a dark Higgs in association with a dark photon via multilepton final states at PADME, expanding the search for new physics beyond the Standard Model.
Findings
Potential to measure or set limits on dark sector models
Identification of rare three e+e- pair final states
Extension of PADME's physics reach
Abstract
The PADME experiment is searching for the Dark Photon in the process, assuming a decay into invisible particles. In extended Dark Sector models, a Dark Higgs can be produced alongside in the process . If the mass is greater than twice the mass the final state will be composed by three pairs. Such extremely rare process is explorable by the PADME experiment, which could get a first measure and impose limits on models of physics beyond the Standard Model.
