The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay --- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, its current state and its eventual fate. The Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan for a world-class experiment dedicated to addressing these questions. LBNE is conceived around three central components: (1) a new, high-intensity neutrino source generated from a megawatt-class proton accelerator at Fermi National Accelerator Laboratory, (2) a near neutrino detector just downstream of the source, and (3) a massive liquid argon time-projection chamber deployed as a far detector deep underground at the Sanford Underground Research Facility. This facility, located at the site of the former Homestake Mine in Lead, South Dakota, is approximately 1,300 km from the neutrino source at Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino charge-parity symmetry violation and mass ordering effects. This ambitious yet cost-effective design incorporates scalability and flexibility and can accommodate a variety of upgrades and contributions. With its exceptional combination of experimental configuration, technical capabilities, and potential for transformative discoveries, LBNE promises to be a vital facility for the field of particle physics worldwide, providing physicists from around the globe with opportunities to collaborate in a twenty to thirty year program of exciting science. In this document we provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess.Comment: Major update of previous version. This is the reference document for LBNE science program and current status. Chapters 1, 3, and 9 provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess. 288 pages, 116 figure

A história de vida em "Ordem & Progresso"

RESUMO Sintetiza os conceitos e as origens da história oral e da história de vida, bem como a sua importância para a pesquisa histórica. Análisa Ordem e Progresso, de Gilberto Freyre, como exemplo do emprego da história de vida na pesquisa social. Sugere que um estudo mais aprofundado de Ordem e Progresso pode esclarecer a presença da história oral na formação de “grandes painéis-síntese” da História do Brasil. ABSTRACT Life History in "Ordem e Progresso". v. 24, n. 1, p. 29-37, jan./jun. 1996. Summarizes the concept and the origins of oral history and the origins and life history as well as their importance to historical research. Analyzes Gilberto Freyre’s Ordem e Progresso (Order and Progress), an example of the use of life history in social research. Suggests that a deeper study of Ordem e Progresso may clear the place of oral history as advice in the making up of great synthesis-pictures of history of Brazil. RÉSUMÉ L’histoire de la vie dans "Ordem e Progresso". v. 24, n. 1, p. 29-37, jan./jun.1996 L’auteur résume les concepts et les origines de l’histoire orale et de l’histoire de la vie ainsi que leur importance pour la recherche historique. Ordem e Progresso, oeuvre de Gilberto Freyre, est analysée et citée comme exemple de l’emploi de l’histoire de vie dans la recherche sociale. Une étude plus approfondie de Ordem e Progresso pourrait mettre en relief la présence de l’histoire orale dans la formation des grands “tableaux-synthèse”de l’Histoire du Brésil
