Reconstructing low mass boosted A→bb at LHCb

LHCb has the ability to trigger low mass objects with high efficiency. Some theoretical models predict low mass resonances decaying to bb ̅. Mass Drop Tagger + Filtering procedure can be used to reconstruct these resonances in boosted regime. This report presents work on Mass Drop Tagger + Filtering parameters optimization in the LHCb kinematic regime. The parameters have been optimized by taking into account signal and background efficiencies and di jet mass resolution.
