Performance of UFO and LC Topo jet collections for the VBF di-Higgs production in the $HH\to b\overline{b}b\overline{b}$ channel in terms of response scale and resolution.

For performance comparison, scale and resolution graphs were created for the mass and energy response of large-radius jets reconstructed from Unified Flow Objects (UFOs) and jets reconstructed only from calorimeter topological clusters (referred to as LC Topo jets) using the SoftDrop and Trimmed groomed truth jet collections, respectively. The analysis was performed on two Monte Carlo simulated data samples based on LHC Run-2 conditions. One of these samples only considered the non-resonant standard model processes for vector boson fusion di-Higgs production, while the other solely contained the resonant process for a graviton decaying to two Higgs bosons. The analysis focused on the di-Higgs to 4b quarks channel exclusively. As a result for both samples, the mass scale showed a good closure of 2% for both jet collections, except at low pT, and the mass resolution was either comparable between the two jet types or the UFO jet collection had a better performance, which is in line with expectations. The energy scale had a good closure of 2-3% and the energy resolution was better for the LC Topo jet collection, as expected due to the LCW calibration.
