Description
The dark photon is a new gauge boson that naturally arises in many beyond the Standard Model theoretical models, featuring
interactions that resemble quantum electrodynamics. Due to this feature, it is often considered the portal between dark and visible
sectors. For this reason, it has become the target of many experimental searches worldwide. In this work, we propose a search for dark
photons based on the Inverse Compton scattering, $\gamma e^- \rightarrow A^\prime e^-$, to be conducted at the Brazilian
Synchrotron Light Laboratory (LNLS). In this setup, photons from a laser source would impinge on the accelerated electron beam
present at the LNLS, producing a dark photon in the final state. Taking advantage of the photon counting technique, we derive the
projected sensitivity of this proposed dark sector detector by considering the energy of the incident photon about 1 eV and an electron
beam of 3 GeV. We show that this experimental setup could pave the way to the first Latin-American Dark Sector detector capable of
covering an unexplored region of parameter space and confirming results from previous searches via astrophysical sources, thus
constituting a promising probe for dark sectors in the future.
