Available in PDF, EPUB and Kindle. Book excerpt: Written by authors working at the forefront of research, this accessible treatment presents the current status of the field of collider-based particle physics at the highest energies available, as well as recent results and experimental techniques. It is clearly divided into three sections; The first covers the physics -- discussing the various aspects of the Standard Model as well as its extensions, explaining important experimental results and highlighting the expectations from the Large Hadron Collider (LHC). The second is dedicated to the involved technologies and detector concepts, and the third covers the important - but often neglected - topics of the organisation and financing of high-energy physics research. A useful resource for students and researchers from high-energy physics.

Book excerpt: This concise primer reviews the latest developments in the field of jets. Jets are collinear sprays of hadrons produced in very high-energy collisions, e.g. at the LHC or at a future hadron collider. They are essential to and ubiquitous in experimental analyses, making their study crucial. At present LHC energies and beyond, massive particles around the electroweak scale are frequently produced with transverse momenta that are much larger than their mass, i.e., boosted. The decay products of such boosted massive objects tend to occupy only a relatively small and confined area of the detector and are observed as a single jet. Jets hence arise from many different sources and it is important to be able to distinguish the rare events with boosted resonances from the large backgrounds originating from Quantum Chromodynamics (QCD). This requires familiarity with the internal properties of jets, such as their different radiation patterns, a field broadly known as jet substructure. This set of notes begins by providing a phenomenological motivation, explaining why the study of jets and their substructure is of particular importance for the current and future program of the LHC, followed by a brief but insightful introduction to QCD and to hadron-collider phenomenology. The next section introduces jets as complex objects constructed from a sequential recombination algorithm. In this context some experimental aspects are also reviewed. Since jet substructure calculations are multi-scale problems that call for all-order treatments (resummations), the bases of such calculations are discussed for simple jet quantities. With these QCD and jet physics ingredients in hand, readers can then dig into jet substructure itself. Accordingly, these notes first highlight the main concepts behind substructure techniques and introduce a list of the main jet substructure tools that have been used over the past decade. Analytic calculations are then provided for several families of tools, the goal being to identify their key characteristics. In closing, the book provides an overview of LHC searches and measurements where jet substructure techniques are used, reviews the main take-home messages, and outlines future perspectives.

Available in PDF, EPUB and Kindle. Book excerpt: Recent experiments seem to be ready to answer the question whether QCD be the correct theory of strong interactions at all scales, or just an effective high-energy line of a yet undiscovered theory. With the upgraded Large Hadron Collider, a proton-proton collision will reach the Center of Mass (CoM) energy of 14 TeV per colliding pair. Perturbative QCD will then be tested with the highest precision. In this realm, the present book begins reviewing QCD with the aim to focus on the Drell-Yan process and the experiments conceived to validate it. In doing this the approach will be exclusively perturbative. Non perturbative techniques, such as lattice QCD, QCD sum rules, or concepts like the MIT bag model will not be discussed.

Available in PDF, EPUB and Kindle. Book excerpt: These proceedings provide a general summary of the theoretical and experimental results which have established QCD as the theory of the strong interactions in the past 20 years. The experimental status of this theory in e⁺e⁻ annihilation, deep inelastic lepton-nucleon scattering and hadron-hadron collisions is reviewed and the theoretical implications are critically discussed. In addition, our knowledge on the non-perturbative sector of QCD, based on lattice and sum rule approaches, is summarized.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of the 17th Workshop of the INFN ELOISATRON Project on "QCD at 200 TeV", held at the "Ettore Majorana" Centre for Scientific Culture, EMCSC, Erice, Trapani, Italy, in the period 11-17 June 1991. The new multi-Te V frontiers of Subnuclear Physics are no more beyond our imagination. A conceptual design of the highest energy (100+100 TeV) proton-proton collider -the ELOISA TRON -already exists. Intensive R & D studies are on the go to develop the most promising and innovative detector technologies for the highest energy and luminosity. QCD (Quantum Chromo-Dynamics) will be the theory to describe the expected Physics scenario of future S upercolliders. The purpose of the Workshop was therefore to review the recent status of QCD in High Energy interactions and to discuss the novel aspects of Perturbative and Non Perturbative QCD with special emphasis on future experimental studies at Super-High Energy Colliders, up to the 200 Te V limit. The topics were: - Classical QCD: particle multiplication, multiplicities and spectra, jet profiles, coherence effects, etc. - Hadron interaction cross-sections and structure functions at Super-High Energies, small-x behaviour, QCD Pomeron, "hot spots"--QCD fragmentation models, present and future. - Artificial neural networks in High Energy Physics. - New theoretical aspects of QCD at Super-High Energies (instanton-induced large cross sections, baryon number violation and peculiar multi-quark production events, etc.)

Book excerpt: The Theoretical Advanced Study Institute (TASI) has become the major summer school for advanced students in elementary particle theory in the United States, offering courses in particle theory, phenomenology, and mathematical physics. The theme of the 1990 school, 'Testing the Standard Model', was chosen because of the many new high precision results that had recently become available from the TEVATRON, SLC, and LEP. The goal was to explore the theoretical background and implications of experiments at these and future facilities, both in and beyond the standard model.

Download or read book Towards Global Interpretation of LHC Data written by Toni Mäkelä and published by Springer Nature. This book was released on 2023-05-16 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first global interpretation of measurements of jet and top quark production at the Large Hadron Collider, including a simultaneous extraction of the standard model parameters together with constraints on new physics, unbiased from the assumptions on the standard model parameters. As a long-standing problem, any hadron collider search for new physics depends on parton distribution functions, which cannot be predicted but are extracted experimentally. However, performing the extraction in the same kinematic region where physics beyond the standard model is expected to manifest causes the risk of absorbing the new physics effects into the parton distributions. In this book, the issue is addressed by extending the standard model by effective contributions from quark contact interactions describing new physics and extracting the parton distributions and standard model parameters simultaneously with setting limits on the contact interactions. In the process, the most precise single measurement of the strong coupling constant at the LHC is performed, to date. Furthermore, the book details the first investigation of the mass renormalization scale dependence of the top quark mass, highlighting the importance of a proper scale choice for obtaining robust predictions and improving the precision of experimental analyses. The initial chapters provide the reader with a succinct yet accessible introduction to the relevant theoretical and experimental topics. The presented investigations are at the edge of precision in the phenomenology of high-energy physics and serve to pave the road toward a global interpretation of LHC data.
