Rare $Z$ Boson Decays to a Hidden Sector

High Energy Physics - Phenomenology 2018-01-22 v2 High Energy Physics - Experiment

Abstract

We demonstrate that rare decays of the Standard Model ZZ boson can be used to discover and characterize the nature of new hidden-sector particles. We propose new searches for these particles in soft, high-multiplicity leptonic final states at the Large Hadron Collider. The proposed searches are sensitive to low-mass particles produced in ZZ decays, and we argue that these striking signatures can shed light on the hidden-sector couplings and mechanism for mass generation.
