    Probing CP Violation with the Deuteron Electric Dipole Moment

    Full text link
    We present an analysis of the electric dipole moment (EDM) of the deuteron as induced by CP-violating operators of dimension 4, 5 and 6 including theta QCD, the EDMs and color EDMs of quarks, four-quark interactions and the Weinberg operator. We demonstrate that the precision goal of the EDM Collaboration's proposal to search for the deuteron EDM, (1-3)\times 10^{-27} e cm, will provide an improvement in sensitivity to these sources of one-two orders of magnitude relative to the existing bounds. We consider in detail the level to which CP-odd phases can be probed within the MSSM.Comment: 5 pages, 4 figures; precision estimates clarified, to appear in Phys. Rev.

    Topological R4R^4 Inflation

    We consider the possibility that higher-curvature corrections could drive inflation after the compactification to four dimensions. Assuming that the low-energy limit of the fundamental theory is eleven-dimensional supergravity to the lowest order, including curvature corrections and taking the descent from eleven dimensions to four via an intermediate five-dimensional theory, as favored by recent considerations of unification at some scale around 1016\sim 10^{16} GeV, we may obtain a simple model of inflation in four dimensions. The effective degrees of freedom are two scalar fields and the metric. The scalars arise as the large five-dimensional modulus and the self-interacting conformal mode of the metric. The effective potential has a local maximum in addition to the more usual minimum. However, the potential is quite flat at the top, and admits topological inflation. We show that the model can resolve cosmological problems and provide a mechanism for structure formation with very little fine tuning.Comment: 25 pages, latex, 2 eps figures, minor changes, accepted for publication in Phys.

    Monitoring industrial research: role and dynamics of corporate R&D: summary report of the first European conference on corporate R&D Seville, 8-9 October 2007

    No full text
    The conference Role and Dynamics of R&D, held on 8-9 October 2007, brought together the community of researchers on corporate R&D to learn about recent developments in the field and outline future avenues of research. A number of aspects of corporate R&D were covered, such as its drivers and determinants, its role in the economy, firm and sector dynamics, and methodological issues. Designated rapporteurs summarisd and documented the most important messages of the papers presented and the debates that followed. This summary report is an edited compilation of their wor
