Subnuclear Physics: Past, Present and Future
Subnuclear Physics: Past, Present and Future International Symposium 30 October - 2 November 2011 – The purpose of the Symposium is to discuss the origin, the status and the future of the new frontier of Physics, the Subnuclear World, whose first two hints were discovered in the middle of the last century: the so-called “Strange Particles” and the “Resonance #++”. It took more than two decades to understand the real meaning of these two great discoveries: the existence of the Subnuclear World with regularities, spontaneously plus directly broken Symmetries, and totally unexpected phenomena including the existence of a new fundamental force of Nature, called Quantum ChromoDynamics. In order to reach this new frontier of our knowledge, new Laboratories were established all over the world, in Europe, in USA and in the former Soviet Union, with thousands of physicists, engineers and specialists in the most advanced technologies, engaged in the implementation of new experiments of ever increasing complexity. At present the most advanced Laboratory in the world is CERN where experiments are being performed with the Large Hadron Collider (LHC), the most powerful collider in the world, which is able to reach the highest energies possible in this satellite of the Sun, called Earth. Understanding the laws governing the Space-time intervals in the range of 10-17 cm and 10-23 sec will allow our form of living matter endowed with Reason to open new horizons in our knowledge.

Particle physics – it matters A forward look at UK research into the building blocks of the Universe and its impact on society In partnership with CONTENTS 3 Foreword 4 Advancing human progress through basic knowledge 5 Why does it matter? 6 New frontiers in basic science 6 The experiments 8 How particle physics benefi ts society 8 Particle physics and healthcare 10 Communications 10 Manufacturing and business 11 Global challenges 12 Helping industry 13 Underpinning the knowledge-based economy 14 Particle physics in the UK 15 Further information 2 Foreword Particle physics – it matters Foreword This report summarises the science questions confronting particle-physics research in the next 20 years, what advances in technology are being pursued and the cross-disciplinary benefi ts to be accrued. It is predominantly an interest in curiosity-driven science, of which particle physics is a major part, that often attracts students to study physics and which drives the technological innovation; neither can proceed in isolation. WHAT IS PARTICLE PHYSICS? Particle physics seeks to understand the evolution of the Universe in the fi rst fraction of a second after its birth in the Big Bang in terms of a small number of fundamental particles and forces. The processes involved ultimately resulted in the creation of atoms and the complex molecules that led to our existence. The intellectual curiosity embodied in particle physics is also at the foundation of philosophy, art and other scientifi c disciplines which, together, have shaped the modern world. Without such innate curiosity, the modern world would not exist. The study of particle physics challenges our preconceptions, inspires and seeks to move human knowledge forward at a basic level – wherever that may lead. -
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.
