    Systematic Effects in Pulse Shape Analysis of HPGe Detector Signals for Neutrinoless Double-Beta Decay

    Victor M Gehman🇺🇸 · Steven R Elliott🇺🇸 · Dongming Mei🇺🇸

    Pulse shape analysis is an important background reduction and signal identification technique for next generation of neutrinoless double-beta decay experiments examining 76Ge. We present a study of the systematic uncertainties in one such parametric pulse-shape analysis technique for separating multi-site backgrounds from single-site signal events. We examined systematic uncertainties for events in full-energy gamma peaks (predominantly multi-site), double escape peaks (predominantly single-site) and the Compton continuum near double-beta decay endpoint (which will be the dominant background for most neutrinoless double-beta decay searches). In short, we find total (statistical plus systematic) fractional uncertainties in the pulse shape cut survival probabilities of: 6.6%, 1.5% and 3.8% for double-escape, continuum and gamma-ray events respectively.

    Physics with the ALICE Electromagnetic Calorimeter

    Rene Bellwied (for the ALICE Collaboration)🇺🇸

    I will present physics measurements which are achievable in the ALICE experiment at the LHC through the inclusion of a new electromagnetic calorimeter. I will focus on jet measurements in proton proton and heavy ion collisions. Detailed simulations have been performed on jet reconstruction, jet triggering, heavy flavor jet reconstruction through electron identification, gamma-jet reconstruction and the measurements of identified hadrons and resonances in jets. I will show the physics capabilities which are made possible through the combination of calorimeter information with the other detector components in ALICE.

    Managing Information for Sparsely Distributed Articles and Readers: The Virtual Journals of the Joint Institute for Nuclear Astrophysics (JINA)

    Richard H. Cyburt🇺🇸 · Sam M. Austin🇺🇸 · Timothy C. Beers · Alfredo Estrade🇺🇸 · Ryan M. Ferguson · A. Sakharuk · Karl Smith · Scott Warren🇺🇸

    The research area of nuclear astrophysics is characterized by a need for information published in tens of journals in several fields and an extremely dilute distribution of researchers. For these reasons it is difficult for researchers, especially students, to be adequately informed of the relevant published research. For example, the commonly employed journal club is inefficient for a group consisting of a professor and his two students. In an attempt to address this problem, we have developed a virtual journal (VJ), a process for collecting and distributing a weekly compendium of articles of interest to researchers in nuclear astrophysics. Subscribers are notified of each VJ issue using an email-list server or an RSS feed. The VJ data base is searchable by topics assigned by the editors, or by keywords. There are two related VJs: the Virtual Journal of Nuclear Astrophysics (JINA VJ), and the SEGUE Virtual Journal (SEGUE VJ). The JINA VJ also serves as a source of new experimental and theoretical information for the JINA REACLIB reaction rate database. References to review articles and popular level articles provide an introduction to the literature for students. The VJs and support information are available at http://groups.nscl.msu.edu/jina/journals
