    Charge asymmetry in K+- --> \pi+-\gamma\gamma induced by the electromagnetic penguin operators

    Full text link
    The CP-violating charge asymmetry in decays K+- --> \pi+- \gamma\gamma, which is induced by the electromagnetic penguin operators, has been studied both in thestandard model and in its extensions. Because of a large enhancement of the Wilson coefficients of the electromagnetic penguin operators in the supersymmetric extensions of the standard model, a significant upper bound on this charge asymmetry could be expected, and thus high precision measurements of this interesting CP-violating quantity might explore new physics effects beyond the standard model.Comment: LaTeX, 10 pages, minor changes, Published versio

    Investigation at a ϕ\phi--factory can shed light on several debated issues in particle physics. We discuss: i) recent theoretical development and experimental progress in kaon physics relevant for the Standard Model tests in the flavor sector, ii) the sensitivity we can reach in probing CPT and Quantum Mechanics from time evolution of entangled kaon states, iii) the interest for improving on the present measurements of non-leptonic and radiative decays of kaons and eta/etaâ€Č^\prime mesons, iv) the contribution to understand the nature of light scalar mesons, and v) the opportunity to search for narrow di-lepton resonances suggested by recent models proposing a hidden dark-matter sector. We also report on the e+e−e^+ e^- physics in the continuum with the measurements of (multi)hadronic cross sections and the study of gamma gamma processes.Comment: 60 pages, 41 figures; added affiliation for one of the authors; added reference to section

    From the Sum of Near-Zero Energy Buildings to the Whole of a Near-Zero Energy Housing Settlement: The Role of Communal Spaces in Performance-Driven Design

    Almost a century ago Modernism challenged the structure of the city and reshaped its physical space in order to, amongst other things, accommodate new transportation infrastructure and road networks proclaiming the,nowadays much-debated ‘scientificated’ pursuit of efficiency for the city. This transformation has had a great impact on the way humans still design, move in, occupy and experience the city. Today major cities in Europe, such as Paris and London, are considering banning vehicles from their historic centers. In parallel, significant effort is currently underway internationally by designers, architects, and engineers to integrate innovative technologies and sophisticated solutions for energy production, management, and storage, as well as for efficient energy consumption, into the architecture of buildings. In general, this effort seeks for new technologies and design methods (e.g., DesignBuilder with EnergyPlus simulation engine; Rhicoceros3D with Grasshopper plugin and Ecotect, Radiance and EnergyPlus tools) that would enable a holistic approach to the spatial design of Near-Zero Energy buildings, so that their ecological benefits are an added value to the architectural design and a building’s visual, and material, impact on its surrounding space. The paper inquires how the integration of such technological infrastructure and performance-orientated interfaces changes yet again the structure and form of cities, and to what extent it safeguards social rights and enables equal access to common resources. Drawing from preliminary results and initial considerations of ongoing research that involve the construction of four innovative NZE settlements across Europe, in the context of the EU-funded ZERO-PLUS project, this paper discusses the integration of novel infrastructure in communal spaces of these settlements. In doing so, it contributes to the debate about smart communities and their role in the sustainable management of housing developments and settlements that are designed and developed with the concept of smart territories

    Impresa e conoscenza nel settore delle utilities: il potenziale ruolo delle corporate universities.

    La centralit\ue0 della conoscenza ai fini dello sviluppo economico costituisce ormai un paradigma e il capitale umano sembra essere il principale fattore idoneo a garantire alla societ\ue0 in cui viviamo uno sviluppo durevole. Da questi presupposti muove il presente studio che ha come oggetto i modelli di formazione d\u2019impresa, e specificatamente la loro declinazione in termini di Corporate University (CU): un ambito di innegabile interesse ai fini dell\u2019analisi delle molteplici forme assunte dal rapporto tra l\u2019organizzazione-impresa e il bene immateriale della conoscenza. La CU pu\uf2 infatti rappresentare una scelta coerente con l\u2019obiettivo delle utilities di diversificarsi ed espandersi su mercati sempre pi\uf9 contendibili e deregolamentati, in particolare quelli del gas e dell\u2019energia elettrica, mantenendo, al contempo, uno stretto legame con le comunit\ue0 territoriali di riferimento
