The SuperCDMS Experiment

Modest improvements in the level and/or discrimination of backgrounds are needed to keep backgrounds negligible during the three phases of SuperCDMS. By developing production designs that require only modest testing, detector production rates may be improved sufficiently to allow an exposure of 500 ton d within a reasonable time and budget. Overall, the improvement estimates described above are conservative. Previous development efforts have shown that some areas prove easier and provide larger factors while others prove more difficult. The conservative estimates together with the broad approach reduce the risk and give us confidence that we will succeed, providing the surest way to probe to WIMP-nucleon cross sections of 10{sup -46} cm{sup 2}.

Influence of debt financing on the effectiveness of the finite duration investment project

The problem of the influence of debt financing on the effectiveness of the arbitrary duration investment project is studied and quantitative results are obtained for the first time. The effectiveness of the investment project is considered from two perspectives: the owners of equity and debt and equity holders only. It was shown, that NPV practically always decreases with leverage in case of a constant value of equity, and the maximum leverage level, at which the project is still effective (NPV > 0), was found. In case of a constant value of the total invested capital it is possible an increase of NPV with leverage as well as its decrease, depending on the relation between the parameters of the project.

The collective excitations of the order parameter in HTSC and heavy fermion superconductors (HFSC) under D-pairing

AbstractWithin the path integral model ofd-pairing for HTSC and HFSC developed recently by P. N. Brusov and N. P. Brusova1, the whole collective mode spectrum has been calculated for the first time for five states of HTSC that arise in their symmetry classification as well as for three states of HFSC.For HTSC the calculations have been made for the
