Additional QCD Background Events for LHCO2020 R&D (signal region only)
收藏资源简介：
These are an additional ~610k QCD dijet background events, in the "signal region" region only (meaning, with mJJ in the range 3.3-3.7 TeV), produced using the same simulation settings as those of the LHCO2020 R&D Dataset. The features are as described at that link: 'pxj1', 'pyj1', 'pzj1', 'mj1', 'tau1j1', 'tau2j1', 'tau3j1', 'pxj2', 'pyj2', 'pzj2', 'mj2', 'tau1j2', 'tau2j2', 'tau3j2' They were used in CATHODE for training the idealized anomaly detector and supervised classifier, as well as for final evaluation of all the anomaly detection methods. <strong>Update September 22, 2023</strong> An additional file was uploaded that contains the momentum 3-vectors of all the particles in each event, in addition to the 14 high level features listed above. As in the original LHCO R&D dataset, up to 700 particles are included, with zero padding for events with fewer than 700 particles. So the shape of the dataset is <pre>(612858, 2114)</pre> with the first 2100 entries corresponding to the 3-momenta, in the order px0,py0,pz0,px1,py1,pz1,...,px699,py699,pz699; and the last 14 entries corresponding to the high level features listed above.
