Description
The Short-Baseline Near Detector (SBND) is a 112-ton liquid argon time projection chamber 110 m away from the Booster Neutrino Beam (BNB) target at Fermilab (Illinois, USA). The close location to the BNB origin makes the experiment sensitive to physics beyond the Standard Model (BSM) produced in the beam. Thanks to its advanced scintillation light detection system, a timing resolution at the nanosecond level further boosts the experiment capabilities.
In this talk, we present the status of searches and expected sensitivities for dark sector particles produced in the decay of mesons and in proton-target interactions in the BNB. We focus on dark photons generated in neutral meson decays and through proton bremsstrahlung, with detection via their visible $e^+e^−$ decay channel, as well as on heavy QCD axions produced through neutral meson mixing and probed in the di-photon final state.
