    This document presents the Conceptual Design Report (CDR) put forward by an international neutrino community to pursue the Deep Underground Neutrino Experiment at the Long-Baseline Neutrino Facility (LBNF/DUNE), a groundbreaking science experiment for long-baseline neutrino oscillation studies and for neutrino astrophysics and nucleon decay searches. The DUNE far detector will be a very large modular liquid argon time-projection chamber (LArTPC) located deep underground, coupled to the LBNF multi-megawatt wide-band neutrino beam. DUNE will also have a high-resolution and high-precision near detector

    Design issues in the British Household Panel Study

    Get PDF
    The British Household Panel Study is the largest single project ever funded by the UK Economic and Social Research Council. Housed in the ESRC's Centre on Micro-social Change in Britain at the University of Essex, the BHPS will comprise an initial 5000 households and 10000 individuals. This paper introduces the Study through an overview of its coverage and some key aspects of its design. A short discussion of some of the analytic advantages of panel data is complemented by three examples of substantive research issues where panel data can assist in our understanding of micro-social change. The BHPS is discussed as an instance of a dynamic approach to social change and its overall rationale is briefly examined. The Study's six substantive research areas - household organisation and dynamics; labour market behaviour and activity; income and wealth dynamics; housing; health; and socio-economic values - are described. The remainder of the paper is concerned with three key design issues for panel studies and explains how these have been tackled on the BHPS. The issues are (1) changing populations; (2) non-sampling errors (and especially non-response and panel conditioning); and (3) sample design. The paper is accompanied by a substantial bibliography on panel design and methodology

    The REDTOP experiment: Rare η/η\eta/\eta^{\prime} Decays To Probe New Physics

    No full text
    The η\eta and η\eta^{\prime} mesons are nearly unique in the particle universe since they are almost Goldstone bosons and the dynamics of their decays are strongly constrained. The integrated η\eta-meson samples collected in earlier experiments amount to 109\sim10^{9} events. A new experiment, REDTOP (Rare Eta Decays To Probe New Physics), is being proposed, with the intent of collecting a data sample of order 1014^{14} η\eta (1012^{12} η\eta^{\prime}) for studying very rare decays. Such statistics are sufficient for investigating several symmetry violations, and for searching for particles and fields beyond the Standard Model. In this work we present several studies evaluating REDTOP sensitivity to processes that couple the Standard Model to New Physics through all four of the so-called \emph{portals}: the Vector, the Scalar, the Axion and the Heavy Lepton portal. The sensitivity of the experiment is also adequate for probing several conservation laws, in particular CPCP, TT and Lepton Universality, and for the determination of the η\eta form factors, which is crucial for the interpretation of the recent measurement of muon g2g-2
