Provides an account of what is now known about physics at scales of to cm. The existence of spin half quarks interacting through colour fields is established fact, as is the structure unifying electromagnetic and weak interaction. In Femtophysics, the author explains the evidence and communicates the essential physics underlying these recent and remarkable developments.
The approach throughout is to obtain results by applying trivial algebra to the content of simple and clear physical pictures. Thus, abstract and difficult concepts can be mastered painlessly while maintaining a firm grip on the essentials. The diligent student, therefore, should acquire a comprehensive understanding of the principles underlying present day particle physics. M Conversi. Evolution of Particle Physics is concerned with the birth of particle physics and its maturation as a scientific field, with emphasis on advances in both theory and experiment.
Topics covered include weak interactions and the breaking of hadron symmetries; the role of complexity in nature; symmetry principles in physics; and isobaric analog resonances in phenomenological nuclear spectroscopy. Adiabatic transformations as well as range and straggling of muons are also discussed. This book is comprised of 24 chapters and begins with a review of some of the most important discoveries in particle physics, along with the tools and techniques that made it possible. The reader is then introduced to symmetry breaking, paying particular attention to hadron symmetries and their connection to weak interactions.
The following chapters explore channeling of ultrarelativistic charged particles in crystals; coherent scattering of high-energy hadrons by light nuclei; elementary particle physics and high-energy physics; and the design and use of large electron synchrotrons. This monograph will be of interest to particle physicists. Cheon Il-t. The unique role of strangeness in nuclear physics has recently attracted much attention, from both the theoretical and experimental viewpoints. This is due not only to the broad spectrum of possible hadron many-body systems with strangeness, but also to the fact that strangeness gives us an opportunity to study fundamental baryon-baryon interactions in a new perspective.
Various aspects of those important and exciting topics are discussed in this book in order to get a perspective of this fast developing area of nuclear physics.

This book presents these experiments, beginning with the discoveries of the neutron and positron, and following them through mesons, strange particles, antiparticles, and quarks and gluons. This second edition contains new chapters on the W and Z bosons, the top quark, B-meson mixing and CP violation, and neutrino oscillations. This book provides an insight into particle physics for researchers, advanced undergraduate and graduate students. I got to know Wolfgang Kummer very well and appreciate his human qualities during his long attachment to CERN , in particular when he served as president of the CERN Council, the highest decision taking authority of this international research centre, from to falling into my term as Director-General….
CERN : A global project. Disk storage at CERN. Mascetti, L. The total usable space available on disk for users is about PB with relative ratios We will describe our operational experience and recent changes to these systems with special emphasis to the present usages for LHC data taking, the convergence to commodity hardware nodes with TB each with optional SSD shared across all services. We also describe our experience in coupling commodity and home-grown solution e. Over the past two years, the operation of the CERN Data Centres went through significant changes with the introduction of new mechanisms for hardware procurement, new services for cloud provisioning and configuration management, among other improvements.
These changes resulted in an increase of resources being operated in a more dynamic environment. To cope with these developments, an evolution of the data centre monitoring tools was also required. This modernisation was based on a number of guiding rules: sustain the increase of resources, adapt to the new dynamic nature of the data centres, make monitoring data easier to share, give more flexibility to Service Managers on how they publish and consume monitoring metrics and logs, establish a common repository of monitoring data, optimise the handling of monitoring notifications, and replace the previous toolset by new open source technologies with large adoption and community support.
This contribution describes how these improvements were delivered, present the architecture and technologies of the new monitoring tools, and review the experience of its production deployment. It also aims to inspire the next generation of physicists and engineers by giving participants the opportunity to be part of a national collaboration of students, teachers and academics, analysing data obtained from detectors based on the ground and in space to make new, curiosity-driven discoveries at school.
Broadly speaking, CERN school consists of a web portal that allows access to data collected by the Langton Ultimate Cosmic ray Intensity Detector LUCID experiment in space and the student-operated Timepix detectors on the ground; a number of Timepix detector kits for ground-based experiments, to be made available to schools for both teaching and research purposes; and educational resources for teachers to use with LUCID data and detector kits in the classroom. By providing access to cutting-edge research equipment, raw data from ground and space-based experiments, CERN school hopes to provide the foundation for a programme that meets the many of the aims and objectives of CERN and the project's supporting academic and industrial partners.
Considers the marketing strategies that underpin the success of the "Cirque du Freak" series. Describes how "Cirque du Freak" is an account of events in the life of schoolboy Darren Shan. Notes that it is another reworking of the vampire narrative, a sub-genre of horror writing that has proved highly popular with both adult and….
Bell, T. CERN has been running a production OpenStack cloud since July to support physics computing and infrastructure services for the site. In the past year, CERN Cloud Infrastructure has seen a constant increase in nodes, virtual machines, users and projects. This paper will present what has been done in order to make the CERN cloud infrastructure scale out. The considerable interest raised by the discovery of neutrino oscillations and recent progress in studies of muon colliders has triggered interest in considering a neutrino factory at CERN.

The general managers then proceed with the presentation of souvenirs to members of the personnel who have 25 years of service in the organization. A gesture of recognition is also given to Zwerner. The du Bois sign.
http://lastsurestart.co.uk/libraries/mspy/2963-software-to.php According to the current literature, the term " du Bois sign" characterizes the condition of a shortened fifth finger as a symptom of congenital syphilis, Down syndrome, dyscrania, and encephalic malformation. Modern medical dictionaries and text books attribute the eponym to the French gynecologist Paul Dubois Yet, a literature analysis revealed incorrect references to the person and unclear definitions of the term. Our findings showed that the origin of the term is based on observations made by the Swiss dermatologist Charles du Bois in connection with congenital syphilis.
In addition, a further eponymical fifth finger sign is closely associated with the du Bois sign. In conclusion, the du Bois sign has only limited diagnostic value and is frequently occurring in the normal healthy population. CERN 's approach to public outreach.

Education and outreach are equally important ways of communicating with the general public, and in particular with the young generation. Over the last decade, CERN has significantly increased its efforts to accommodate the very large interest of the general public about , visit requests per year , by ramping up its capacity for guided tours from 25, to more than , visitors per year, by creating six new of state-of-the-art exhibitions on-site, by building and operating a modern physics laboratory for school teachers and students, and by showing several traveling exhibitions in about 10 countries per year.
The offer for school teachers has also been expanded, to weeks of teacher courses with more than participants from more than 50 countries per year. The talk will give an overview about these and related activities. Large-scale long-term projects such as the LHC require the ability to store, manage, organize and distribute large amounts of engineering information, covering a wide spectrum of fields.
This information is a living material, evolving in time, following specific lifecycles. It has to reach the next generations of engineers so they understand how their predecessors designed, crafted, operated and maintained the most complex machines ever built. Over the years, human collaborations and machines grew in size and complexity. So did EDMS: it is currently home to more than 2 million files and documents, and has over 6 thousand active users. In April we released a new major version of EDMS, featuring a complete makeover of the web interface, improved responsiveness and enhanced functionality.
Following the results of user surveys and building upon feedback received from key users group, we brought what we think is a system that is more attractive and makes it easy to perform complex tasks.
In this paper we will describe the main functions and the architecture of EDMS. We will discuss the available integration options, which enable further evolution and automation of engineering data management.
We will also present our plans for the future development of EDMS. Cordeiro, C. By the end of more than 10 Million core-hours of computing resources have been delivered by several commercial cloud providers to the four LHC experiments to run their production workloads, from simulation to full chain processing.
In this paper we describe the experience gained at CERN in procuring and exploiting commercial cloud resources for the computing needs of the LHC experiments.
