title: "Additional Table 1 (2016preVFP event level Cutflow)" of "Search for light pseudoscalar bosons, pair-produced in Higgs boson decays in the four-electron final state in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Trigger-level and overall event-level efficiency.Definitions used in this table: Trigger efficiency is defined as the number of events passing both the trigger and the HAA4e offline selection, divided by the number passing the offline selection alone. Number of normalized events passing all selections gives the luminosity-scaled event yield after applying all cuts. Total event efficiency is the fraction of generated events in which a four-electron invariant mass is successfully reconstructed within the 80-250 GeV range, with event weights applied.
description: A search for pairs of light neutral pseudoscalar bosons ($ A$) resulting from the decay of a Higgs boson is performed. The search is conducted using LHC proton-proton collision data at $\sqrt{s} = 13~\mathrm{TeV}$, collected with the CMS detector in 2016--2018 and corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$. The $ A$ boson decays into a highly collimated electron-positron pair. A novel multivariate algorithm using tracks and calorimeter information is developed to identify these distinctive signatures, and events are selected with two such merged electron-positron pairs. No significant excess above the standard model background predictions is observed. Upper limits on the branching fraction for $ H\to A A\to4 e$ are set at $95\%$ confidence level, for masses between 10 and 100 MeV and proper decay lengths below 100 $\mu\mathrm{m}$ ; reaching branching fraction sensitivities as low as $10^{-5}$. This is the first search for Higgs boson decays to four electrons via light pseudoscalars at the LHC. It significantly improves the experimental sensitivity to axion-like particles with masses below 100 MeV.

description: Selection efficiencies for the barrel region at object level. Definitions used in this table: Track-Match efficiency (barrel / endcap) is the fraction of reconstructed superclusters matched to at least two tracks (within a ΔR &lt; 0.15 cone) with $p_T$&gt;25GeV, normalized to the number of generated electron pairs. Merged-electron-pair (MEP) reconstruction efficiency (barrel / endcap) is the fraction of events in which an MEP is successfully reconstructed, using the same normalization. Iso-cuts efficiency (barrel / endcap) is the fraction of reconstructed MEPs that pass the isolation requirement. BDT efficiency (barrel / endcap) is the fraction of MEPs that pass the BDT selection among those passing the isolation requirement. Merged-electron-pair ID efficiency (barrel / endcap) is the fraction of MEPs that satisfy all signal-selection criteria, again normalized to the number of generated electron pairs.

description: Dataset Description

This repository contains a dataset of object detection and instance segmentation events recorded over a 34-day period, from September 19, 2023 to October 23, 2023. The dataset comprises 50,384 individual records, capturing temporal, spatial, and classification data for objects identified in a open access video broadcast from the town of Morella, Spain.

Dataset Structure

The repository contains a single file, detections.csv.

detections.csv serves as the primary dataset file. It encapsulates granular detection events, where each record includes the temporal timestamp, categorical class ID, model confidence metric, and spatial geometry. Comprehensive details regarding these columns are provided in the section below.
