Additional QCD Background Events for LHCO2020 R&D (signal region only)

<p>These are an additional ~610k QCD dijet background events, in the &quot;signal region&quot; region only (meaning, with mJJ in the range 3.3-3.7 TeV), produced using the same simulation settings as those of the <a href="https://doi.org/10.5281/zenodo.2629072">LHCO2020 R&amp;D Dataset</a>. The features are as described at that link:</p> <p>&#39;pxj1&#39;, &#39;pyj1&#39;, &#39;pzj1&#39;, &#39;mj1&#39;, &#39;tau1j1&#39;, &#39;tau2j1&#39;, &#39;tau3j1&#39;, &#39;pxj2&#39;, &#39;pyj2&#39;, &#39;pzj2&#39;, &#39;mj2&#39;, &#39;tau1j2&#39;, &#39;tau2j2&#39;, &#39;tau3j2&#39;</p> <p>They were used in <a href="https://arxiv.org/abs/2109.00546">CATHODE</a>&nbsp;for training the idealized anomaly detector and supervised classifier, as well as for final evaluation of all the anomaly detection methods.&nbsp;</p> <p><strong>Update September 22, 2023</strong></p> <p>An additional file was uploaded that contains&nbsp;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&amp;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&nbsp;</p> <pre>(612858, 2114)</pre> <p>with the first 2100 entries corresponding to the 3-momenta, in the order&nbsp;px0,py0,pz0,px1,py1,pz1,...,px699,py699,pz699;&nbsp;and the last 14 entries corresponding to the high level features listed above.&nbsp;</p>
