The dataset comprises simulated events from pp collisions at 13 TeV. Standard Model (SM) background events and a diverse set of beyond Standard Model (BSM) signals with 2 leptons, 1 b-jet and H_T > 500 GeV in the final state were simulated. The SM background was generated at leading order, and it includes Z+jets, ttbar, WW, WZ and ZZ subsamples. The processes were generated in kinematic regions to ensure good statistics across the whole phase space. The sampling was carried out using event generation filters at parton level as follows: ttbar: pT <100 GeV; pT in [100, 250] GeV; pT > 250 GeV The scalar sum of the pT of outgoing particles (ST) for Z+Jet: ST < 250 Gev; ST in [250, 500] GeV; ST > 500 GeV W/Z pT for dibosons: pT < 250 GeV; pT in [250, 500] GeV; pT > 500 GeV The BSM signals include: Pair production of heavy vector-like T quarks, with T masses mT = {1.0, 1.4} TeV; tZ production through a flavour-changing neutral current vertex; Production of a Randall-Sundrum radion R with mR = 4 TeV; Top quark pair production in association with a heavy Higgs boson H' (2HDM), with mH' = 400 GeV; Production of W_R, decaying N_R, and a charged lepton, with masses mW_R = 6.5 TeV and mN_R = 1.5 TeV (Left-Right Symmetric Model). All samples were generated using MadGraph5 2.6.5, and the detector was simulated using Delphes 3 with the default CMS card. Pythia 8.2 was used for the hadronisation of the events. The features are in Cartesian coordinates, and the accumulation at zeros from non-reconstructed objects (i.e. missing values) is removed. Each file provides a train:validation:test split with the ratio 1:1:1 to ensure equal statistical description of the events. The events were generated with the support of the Nacional de Computação Avançada (CNCA) under the 2023.10635.CPCA.A1 project.
