Abstract: The ATLAS detector at the Large Hadron Collider reads out particle collision data from over 100 million electronic channels at a rate of approximately 100 kHz, with a recording rate for physics events of approximately 1 kHz. Before being certified for physics analysis at computer centres worldwide, the data must be scrutinised to ensure they are clean from any hardware or software related issues that may compromise their integrity. Prompt identification of these issues permits fast action to investigate, correct and potentially prevent future such problems that could render the data unusable. This is achieved through the monitoring of detector-level quantities and reconstructed collision event characteristics at key stages of the data processing chain. This paper presents the monitoring and assessment procedures in place at ATLAS during 2015-2018 data-taking. Through the continuous improvement of operational procedures, ATLAS achieved a high data quality efficiency, with 95.6% of the recorded proton-proton collision data collected at √s=13 TeV certified for physics analysis

The Higgs boson discovery at the Large Hadron Collider in 2012 relied on boosted decision trees. Since then, high energy physics (HEP) has applied modern machine learning (ML) techniques to all stages of the data analysis pipeline, from raw data processing to statistical analysis. The unique requirements of HEP data analysis, the availability of high-quality simulators, the complexity of the data structures (which rarely are image-like), the control of uncertainties expected from scientific measurements, and the exabyte-scale datasets require the development of HEP-specific ML techniques. While these developments proceed at full speed along many paths, the nineteen reviews in this book offer a self-contained, pedagogical introduction to ML models' real-life applications in HEP, written by some of the foremost experts in their area.

Supersymmetry (SUSY) introduces superpartners of the Standard Model (SM) particles. If their masses are typically O(100 GeV) ∼ O(TeV), a lightest neutralino can be a candidate for the dark matter, and the problem is solved by canceling the correction of the Higgs boson mass. Further, SUSY can explain the experimental result of the muon magnetic moment (g-2). This book presents a search for electroweakinos—the superpartners of the SM electroweak bosons—such as charginos and neutralinos using data at the LHC collected by the ATLAS detector. Pair-produced electroweakinos decay into the light ones and SM bosons (W/Z/h), and with the large mass difference between the heavy and light electroweakinos, the SM bosons have high momenta. In a fully hadronic final state, quarks decayed from the bosons are collimated, and can consequently be reconstructed as a single large-radius jet. This search has three advantages. The first is a statistical benefit by large branching ratios of the SM bosons. The second is to use characteristic signatures—the mass and substructure—of jets to identify as the SM bosons. The last is a small dependency on the signal model by targeting all the SM bosons. Thanks to them, the sensitivity is significantly improved compared to the previous analyses. Exclusion limits at the 95% confidence level on the heavy electroweakino mass parameter are set as a function of the light electroweakino mass parameter. They are set on wino or higgsino production models with various assumptions, such as the branching ratio of their decaying and the type of lightest SUSY particle. These limits are the most stringent limits. Besides, this book provides the most stringent constraints on SUSY scenarios motivated by the dark matter, the muon g-2 anomaly, and the naturalness.

Big Science, Innovation, and Societal Contributions offers a connection between Big Science and its societal impacts from a multidisciplinary perspective, drawing on physics and astrophysics scholars to explain the reasoning behind their work, and how such knowledge can be applied to everyday life. Through simplifying complex scientific concepts, Big Science, Innovation, and Societal Contributions explains the evolution of Big Science experiments and what it takes to manage and maintain complex scientific experiments with a human centred approach. Further, it examines the motivations behind international efforts to develop capital-intensive and human resource-rich, large-scale multi-national scientific investments to solve fundamental research problems concerning our future. Drawing on reliable scientific evidence, multi-disciplinary perspectives, and personal insights from collider physics, detectors, accelerator, and telescopes research, the volume outlines the mechanisms, benefits, and methodologies, as well as the potential challenges and short-comings, of Big Science, to learn and reflect on for future initiatives. This is an open access title available under the terms of a [CC BY-NC-ND 4.0 International] licence.

Comparative Genomics is the field of knowledge dedicated to the analysis and comparison of genes and genomes. The scientific areas comprised in this field include subjects as diverse as (just naming a few): 1) the development of algorithms for the alignment of genes, whole genomes, short- and long sequencing reads, 2) the search for remote sequence similarity, 3) the discovery of motifs and sequence patterns, 4) the identification of gene families, 5) the detection of ortholog/paralog groups, 6) the reconstruction of evolutionary history of the genes, 7) the detection of signs of selective forces exerted over genes and genomes, 8) the reconstruction of ancestral DNA and genome sequences, 9) the detection and analysis of genome synteny, 10) the inference of ancestral gene order, among others. In addition, an important new sub-field of Comparative Genomics has emerged in the last decade, referred to as Pangenomics, making available improved tools to analyze the exponential genomic data accumulating since the development of Second- and Third-Generation Sequencing Technologies.
