Fragmentation into b hadrons

The fragmentation process of b quarks into b hadrons, produced in Z decays or pp collisions, cannot be fully described perturbatively but relies on phenomenological models. To test and tune the parameters of these models, precise experimental measurements have to be performed. Furthermore, properties of the b hadron production process affect many analyses dealing with decays of b hadrons. Thus, precise knowledge of the fragmentation properties allows more accurate measurements in this field. New results for the b fragmentation function and b hadron production fractions have been submitted to this conference and will be summarised in this article. Combined results for b hadron production rates will also be given. (8 refs)

B spectroscopy using all-to-all propagators

We measure the ground and excited states for B mesons in the static limit using maximally variance reduced estimators for light quark propagators. Because of the large number of propagators we are able to measure accurately also orbitally excited P, D and F states. We also present some results for Lambda_b.Comment: 3 pages, 3 figures.

Beyond Brooke Group: Bringing Reality to the Law of Predatory Pricing

This Feature offers a roadmap for bringing and deciding predatory pricing cases under the Supreme Court’s restrictive Brooke Group decision. Brooke Group requires a plaintiff to show that the defendant set a price below cost and had a sufficient likelihood of recouping its investment in predation. This framework, which was adopted without any contested presentation of its merits, has endured despite its flaws. Beyond this framework, the Court opined in dicta that predation is implausible. We identify points of flexibility within the Court’s framework that permit an empirically grounded evaluation of the predation claim. Under the price-cost test, a plaintiff has leeway to select an appropriate measure of cost, including incremental cost. In considering recoupment, Brooke Group’s skeptical dicta should be confined to the particular market structure and theory of recoupment analyzed in that case. The dicta do not apply, for example, to a monopolist who recoups by earning a reputation for predation. A further reason to confine Brooke Group’s dicta is the Court’s highly unusual reweighing of the evidence presented at trial. As we explain using new historical research, this was not the Court’s initial plan after oral argument, but Justice Kennedy switched his vote. We also make the case against extending the price-cost test to more complex pricing strategies, such as loyalty discounts, in which the motivation for a stringent rule—to avoid costly false positives—has little purchase

Postfeminism, popular feminism and neoliberal feminism? Sarah Banet-Weiser, Rosalind Gill and Catherine Rottenberg in conversation

In this unconventional article, Sarah Banet-Weiser, Rosalind Gill and Catherine Rottenberg conduct a three-way ‘conversation’ in which they all take turns outlining how they understand the relationship among postfeminism, popular feminism and neoliberal feminism. It begins with a short introduction, and then Ros, Sarah and Catherine each define the term they have become associated with. This is followed by another round in which they discuss the overlaps, similarities and disjunctures among the terms, and the article ends with how each one understands the current mediated feminist landscape

Physics Analysis Expert PAX: First Applications

PAX (Physics Analysis Expert) is a novel, C++ based toolkit designed to assist teams in particle physics data analysis issues. The core of PAX are event interpretation containers, holding relevant information about and possible interpretations of a physics event. Providing this new level of abstraction beyond the results of the detector reconstruction programs, PAX facilitates the buildup and use of modern analysis factories. Class structure and user command syntax of PAX are set up to support expert teams as well as newcomers in preparing for the challenges expected to arise in the data analysis at future hadron colliders.Comment: Talk from the 2003 Computing in High Energy and Nuclear Physics (CHEP03), La Jolla, Ca, USA, March 2003, 7 pages, LaTeX, 10 eps figures.
