Description

Searches for beyond the SM physics can involve heavy resonances identified by multi-prong jets. Calibration techniques rely on SM candles, which makes it challenging to calibrate jets with more than three prongs. This talk will highlight a new method for calibrating the tagging of multi-prong jets using the Lund Jet Plane to correct the substructure of simulated jets. The technique is based on reclustering a multi-prong such that each prong is contained in a separate subjet. The substructure of each prong is then corrected via data-driven reweighting of splittings in the Lund Jet Plane. The method is shown to improve the data-simulation agreement of substructure observables significantly. This will enable future searches utilizing high prong jets.
