Searching for long-lived dark photons with the Heavy Photon Search experiment
ORAL
Abstract
A popular model for light (sub-GeV) Dark Matter is that its constituents belong to a Hidden Sector, uncharged under the Standard Model (SM) forces, and coupled to the SM through a new force carrier. This coupling can be realized through a theoretically well-motivated minimal extension to the SM that introduces a new light U(1) gauge boson, referred to as dark photon A’. The kinetic mixing of dark and SM photons opens a production channel for dark photons analogous to bremsstrahlung in which an electron radiates off an A’.
The Heavy Photon Search (HPS) at the Thomas Jefferson National Accelerator Facility has been primarily designed to search for electro-produced dark photons decaying into electron-positron pairs. In particular, HPS is sensitive to an experimental signature where long-lived dark photons decay displaced from the target. In this talk, I will briefly illustrate the design and performance of the HPS detector before describing the procedure of the displaced vertex analysis.
