The Discovery of the Higgs Boson at the LHC
Chapter 6 The Discovery of the Higgs Boson at the LHC Peter Jenni and Tejinder S. Virdee 6.1 Introduction and the Standard Model The standard model of particle physics (SM) is a theory that is based upon principles of great beauty and simplicity. The theory comprises the building blocks of visible matter, the fundamental fermions: quarks and leptons, and the fundamental bosons that mediate three of the four fundamental interactions; photons for electromag- netism, the W and Z bosons for the weak interaction and gluons for the strong interaction (Fig. 6.1). The SM provides a very successful description of the visible universe and has been verified in many experiments to a very high precision. It has an enormous range of applicability and validity. So far no significant deviations have been observed experimentally. The possibility of installing a proton-proton accelerator in the LEP tunnel, after the e+e− programme, was being discussed in the 1980’s. At the time there were many profound open questions in particle physics, and several are still present. In simple terms these are: what is the origin of mass i.e. how do fundamental particles acquire mass, and why do they have the masses that they have? Why is there more matter than anti-matter? What is dark matter? What is the path towards unification of all forces? Do we live in a world with more space-time dimensions than the familiar four? The LHC [1, 2] was conceived to address or shed light on these questions. P. Jenni CERN, Geneva, Switzerland Albert-Ludwigs University Freiburg, Freiburg im Breisgau, Germany T. -
Calorimetry for Particle Physics
REVIEWS OF MODERN PHYSICS, VOLUME 75, OCTOBER 2003 Calorimetry for particle physics Christian W. Fabjan and Fabiola Gianotti CERN, 1211 Geneva 23, Switzerland (Published 15 October 2003) Calorimetry has become a well-understood, powerful, and versatile measurement method. Besides perfecting this technique to match increasingly demanding operation at high-energy particle accelerators, physicists are developing low-temperature calorimeters to extend detection down to ever lower energies, and atmospheric and deep-sea calorimeters to scrutinize the universe up to the highest energies. The authors summarize the state of the art, with emphasis on the physics of the detectors and innovative technologies. CONTENTS VI. Citius, Altius, Fortius 1280 A. Introduction 1280 B.

Prhep Hep2001
International Europhysics Conference on HEP PROCEEDINGS Searches for new particles at Colliders Fabiola Gianotti∗ CERN, EP Division, 1211 Gen`eve 23, Switzerland E-mail: [email protected] Abstract: Most recent results from the searches for new particles at LEP, Tevatron and PrHEP hep2001 HERA, presented at the 2001 Summer Conferences, are reviewed. Prospects at future machines (LHC and Linear Colliders) are also discussed. The emphasis is put on the quest for Higgs bosons, Supersymmetry, Extra-dimensions and Flavour-Changing Neu- tral Current processes. In each case, the phenomenological framework, the experimental strategies, and the analysis methods are described, and the sensitivity and reach of the various machines are compared. 1. Introduction The search for new particles is one of the most exciting, rapidly-evolving and prolific fields in today’s high-energy experimental physics, motivated also by a rich spectrum of theoretical scenarios and predictions. Over the last years, the three operational high-energy Colliders, LEP, Tevatron and HERA, have explored the few hundred GeV energy range and set stringent bounds on various models. In addition, recently LEP has reported an exciting 2σ hint in the search for a Standard Model (SM) Higgs boson of mass about 115 GeV, and the H1 experiment at HERA has observed an excess of W ’s produced in association with a high transverse momentum hadronic system. Since 1996, i.e. since the beginning of its phase two, LEP has delivered an integrated 1 luminosity of about 700 pb− per experiment at a centre-of-mass energy above the W -pair production threshold. The machine performance in terms of both energy and luminosity went beyond any optimistic expectation. -
