    Particle Correlations at LEP

    Full text link
    Particle correlations are extensively studied to obtain information about the dynamics of hadron production. From 1989 to 2000 the four LEP collaborations recorded more than 16 million hadronic Z0 decays and several thousand W+W- events. In Z0 decays, two-particle correlations were analysed in detail to study Bose-Einstein and Fermi-Dirac correlations for various particle species. In fully-hadronic W+W- decays, particle correlations were used to study whether the two W bosons decay independently. A review of selected results is presented.Comment: To appear in the proceedings of the first High-Energy Physics Conference in Madagascar (HEP-MAD'01), Antananarivo, Madagascar, 27 Sep - 5 Oct 2001 OPAL conference report CR48

    A Copyright Right of Publicity

    Get PDF
    This Article identifies a striking asymmetry in the law’s disparate treatment of publicity-rights holders and copyright holders. State-law publicity rights generally protect individuals from unauthorized use of their name and likeness by others. Publicity-claim liability, however, is limited by the First Amendment’s protection for expressive speech embodying a “transformative use” of the publicity-rights holder’s identity. This Article examines for the first time a further limitation imposed by copyright law: when a publicity-rights holder’s identity is transformatively depicted in a copyrighted work without consent, the author’s copyright can produce the peculiar result of enjoining the publicity-rights holder from using or engaging in speech about her own depiction. This Article offers novel contributions to the literature on copyright overreach and: (1) identifies a legal asymmetry produced in the interplay of publicity rights, copyright law, and the First Amendment; (2) examines the burdens on constitutionally protected speech, autonomy, and liberty interests of publicity-rights holders when copyright law prevents or constrains use of their own depiction; and (3) outlines a framework for recognizing a “copyright right of publicity” to exempt the publicity-rights holder’s use from copyright infringement liability. Notably, this Article contributes uniquely to the literature by revealing new insights gained from an exclusive first-hand perspective of an internationally recognized celebrity whose persona was prominently depicted without prior notice or consent in a wide-release feature film

    Causation and the Law: Preemption, Lawful Sufficiency, and Causal Sufficiency

    Get PDF
    This article briefly describes the normative/nonnormative distinction, and how one might invoke this distinction to locate a nonnormative dimension of actual causation. After briefly introducing Richard Wright\u27s concept of a necessary element in a set of conditions for an effect, the article notes ambiguities in the critical concepts of necessity and sufficiency that he deploys. The article suggests the most plausible interpretation of Wright\u27s use of different modal concepts

    Inheritance Forgery

    Many venerable norms in inheritance law were designed to prevent forgery. Most prominently, since 1837, the Wills Act has required testators to express their last wishes in a signed and witnessed writing. Likewise, the court-supervised probate process helped ensure that a donative instrument was genuine and that assets passed to their rightful owners. But in the mid-twentieth century, concern about forgery waned. Based in part on the perception that counterfeit estate plans are rare, several states relaxed the Wills Act and authorized new formalities for notarized and even digital wills. In addition, lawmakers encouraged owners to bypass probate altogether by transmitting wealth through devices such as life insurance and transfer-on-death deeds. This Article offers a fresh look at inheritance-related forgery. Cutting against the conventional wisdom, it discovers that counterfeit donative instruments are a serious problem. Using reported cases, empirical research, grand jury investigations, and media stories, it reveals that courts routinely adjudicate credible claims that wills, deeds, and life insurance beneficiary designations are illegitimate. The Article then argues that the persistence of inheritance-related forgeries casts doubt on the wisdom of some recent innovations, including statutes that permit notarized and electronic wills. The Article also challenges well-established inheritance law norms, including the litigation presumptions in will-forgery contests, the widespread practice of rubber-stamping deeds, and the delegation of responsibility for authenticating a nonprobate transfer to private companies. Finally, the Article outlines reforms to modernize succession while remaining sensitive to the risks of forgery

    Meteorites and the Origin of Habitable Worlds On November 30, 2011, Dr. Monika Kress spoke in the University Scholar Series hosted by Provost Gerry Selter at the Dr. Martin Luther King, Jr. Library. Monika Kress is an Associate Professor of Physics and Astronomy at SJSU and also a member of the NASA Astrobiology Institute\u27s Virtual Planetary Laboratory. In this seminar, she presents the theory of solar system formation, focusing on meteorites. Dr. Kress also describes a first-hand account of how meteorites are recovered from the most fertile meteorite-hunting ground on Earth: Antarcticahttps://scholarworks.sjsu.edu/uss/1010/thumbnail.jp

    Study directed at development of an implantable biotelemetry ion detector

    A literature search was conducted to currently update known information in the field of ion-selective electrodes. The review attempts to identify present trends in cation and anions selective electrodes pertinent to the area of bioimplantable units. An electronic circuit was designed to provide the high impedance interface between the ion-selective sensors and signal-processing equipment. The resulting design emphasized the need for low power and miniaturization. Many of the circuits were constructed and used to evaluate the ion-selective electrodes. A cuvette capable of holding the ion-selective and the reference electrodes was designed and constructed. This equipment was used to evaluate commercially available ion-selective electrodes and the electrodes designed and constructed in the study. The results of the electrode tests are included

    Polarization and Spin Alignment in Multihadronic Z0 Decays

    The large statistics of millions of hadronic Z0 decays, accumulated by the four LEP experiments between 1989 and 1995, allowed for detailed investigations of the fragmentation process. Inclusive Lambda_b baryons and Lambda hyperons at intermediate and high momentum have been found to show longitudinal polarization. This may be related to the primary quark and antiquark polarization and the hadronization mechanism which produces the leading baryons. Helicity density-matrix elements have been measured for a variety of vector mesons produced inclusively in hadronic Z0 decays. The diagonal elements of some of the light mesons and the D*+- show a preference for a helicity-zero state if the meson carries a large fraction of the available energy. The mechanism which produces such spin alignment in the non-perturbative hadronization of the primary partons to the vector mesons is so far unexplained. For the B* the results are consistent with no spin alignment, which is expected in a picture based on HQET. For some meson species non-diagonal elements have been measured indicating coherence phenomena due to final-state interaction between the primary quark and antiquark.Comment: Jan 2001. 6pp. To be published in the proceedings of 30th International Symposium on Multiparticle Dynamics (ISMD 2000), Tihany, Lake Balaton, Hungary, 9-15 Oct 2000 ;updated version: minor stylistic modifications as suggested by the edito
