We review some recent theoretical progress in the understanding of weak radiative B meson decay, and discuss the implications of present and improved measurements of b → sγ for supersymmetric models. Talk presented at Beauty ’97, Fifth International Workshop on B-Physics at Hadron Machines, Los Angeles, CA, October 13-17, 1997. To be published in Nuclear Instruments and Methods in Physics Resea...

In this paper, we look at the prospects for mobilization of the wealthy to contest widening income inequality. We begin by looking at members of an organization that supports the mobilization of grassroots groups on behalf of economic justice. We found among its members an “unexpected voice” – the voice of wealthy people grappling with their fairly invisible wealth and their own surprise that i...

We report results on fB and semi-leptonic B decay form factors using NRQCD. We investigate 1/M scaling behavior of decay amplitudes. For fB Effect of higher order relativistic correction terms are also studied.

We review recent experimental results on hadronic decays and lifetimes of hadrons containing b and c quarks[1]. We discuss charm counting and the semileptonic branching fraction in B decays, the color suppressed amplitude in B decay, and the search for gluonic penguins in B decay. A complete picture of inclusive B decay is beginning to emerge from recent measurements by CLEO II and the LEP expe...

A selection of recent heavyavor results from OPAL using the LEP1 data sample are presented. The average polarization of b baryons in hadronic Z decay has been measured to be 0:56 0:13(stat:) 0:09(syst:) using semileptonic decays of b baryons. A search has been conducted for the radially excited D 0 and has produced a 95% CL upper limit on its production of f(Z ! D 0 (2629)) Br(D 0 ! D + ) < 2:1...

AIMS Because logistical and financial obstacles impede using large prospective cohort studies, surveillance decisions in occupational settings must often be made without evidence of relative benefits and costs. Using the example of isocyanate induced asthma, the most commonly reported immune mediated occupational asthma, the authors developed a model based approach to evaluate the costs and ben...
