    Using data collected with the BESII detector at e+ee^{+}e^{-} storage ring Beijing Electron Positron Collider, the measurements of relative branching fractions for seven Cabibbo suppressed hadronic weak decays D0KK+D^0 \to K^- K^+, π+π\pi^+ \pi^-, KK+π+πK^- K^+ \pi^+ \pi^- and π+π+ππ\pi^+ \pi^+ \pi^- \pi^-, D+K0ˉK+D^+ \to \bar{K^0} K^+, KK+π+K^- K^+ \pi^+ and ππ+π+\pi^- \pi^+ \pi^+ are presented.Comment: 11 pages, 5 figure

    The DUNE Far Detector Interim Design Report, Volume 3: Dual-Phase Module

    Get PDF
    The DUNE IDR describes the proposed physics program and technical designs of the DUNE far detector modules in preparation for the full TDR to be published in 2019. It is intended as an intermediate milestone on the path to a full TDR, justifying the technical choices that flow down from the high-level physics goals through requirements at all levels of the Project. These design choices will enable the DUNE experiment to make the ground-breaking discoveries that will help to answer fundamental physics questions. Volume 3 describes the dual-phase module's subsystems, the technical coordination required for its design, construction, installation, and integration, and its organizational structure

These design choices will enable the DUNE experiment to make the ground-breaking discoveries that will help to answer fundamental physics questions. Volume 1 contains an executive summary that describes the general aims of this document. The remainder of this first volume provides a more detailed description of the DUNE physics program that drives the choice of detector technologies. It also includes concise outlines of two overarching systems that have not yet evolved to consortium structures: computing and calibration. Volumes 2 and 3 of this IDR describe, for the single-phase and dual-phase technologies, respectively, each detector module's subsystems, the technical coordination required for its design, construction, installation, and integration, and its organizational structure

    Managerial myopia, financial expertise, and executive-firm matching

    Funding: FCT - Fundacao para a Ciencia e Tecnologia (UID/ECO/00124/2013 ) and POR Lisboa (LISBOA-01-0145-FEDER-007722)Existing literature emphasizes skills-based explanations for executive-firm matching, namely in the context of financial expertise. In contrast, our paper argues that informational concerns may also be relevant. We model a public firm with a project opportunity of uncertain quality, where long-run shareholders choose between hiring an operational manager or a financial expert. These managers are equally myopic, however financial experts are also privy to stock-market beliefs. Financial experts invest sub-optimally due to catering incentives, while operational managers tend to engage in signaling-driven overinvestment. We show that operational managers are preferred for low-NPV projects or when stock markets are well informed.authorsversionpublishe
