Note: The Standard Model (SM) of particle physics provides a cogent, yet incomplete, description of matter and its fundamental interactions. Many theories aim to describe particles and forces beyond the SM of particle physics, but after ten years of data taking at the Large Hadron Collider (LHC) and hundreds of experimental measurements, only one deviation from the predictions of the SM has been observed .The Standard Model (SM) of particle physics provides a cogent, yet incomplete, description of matter and its fundamental interactions. Many theories aim to describe particles and forces beyond the SM of particle physics, but after ten years of data taking at the Large Hadron Collider and hundreds of experimental measurements, only one deviation from the predictions of the SM has been observed in a series of semi-leptonic decays of B-mesons (B anomalies). It is undeniable though that the third generation of fermion families have a special role in the SM and beyond and their study represents the pathway towards accessing new particles and forces. Taking into account the current exploitation of LHC data and the constraints set to new particles and forces in recent years, it is time to devote greater scientific focus to the search for new light particles that specially couple to third generation quarks. These particles might be within reach of the LHC, but haven’t been discovered yet due to experimental limitations (triggers). BARD is a new experimental technique that overcomes the limitations of light particle searches and provides a new way of performing data analysis searches for these particles. BARD will achieve this goal by advancing high-momentum resonance search methods using tools specific to the low-momentum B-physics field, in order to increase the available dataset and sensitivity for di-b-jet resonance particles. BARD’s innovation, exploiting the full LHC Run-3 data-taking, will provide a concrete chance at discovering these new particles.
