The Johannine Community as a Constructed, Imagined Community

The article takes issue with recent attempts to deny that the New Testament Gospels were addressed to distinct early Christian communities and argues that it is still meaningful to trace how these writings construct distinct early Christian identities. The author applies the social identity approach and concepts related to the symbolic construction of communities and imagined communities to explain how an ideal portrait of the community of Jesus’ followers is created in the Gospel of John. The article argues that this portrait constructs social reality rather than reflects it in any transparent way. The author demonstrates how John anchors his story of Jesus to mythical beginnings and uses various dualistic polarities to express a clear demarcation between Jesus’ followers and the rest of world. In the Gospel, the knowledge of God communicated only by Jesus and the mutual love between Jesus’ disciples function as strong symbols of belonging for Jesus’ followers but also create an imagined boundary between them and those who have not received Jesus’ revelation. The author argues that the Gospel writer has embedded his story of Jesus in a mythical framework in order to naturalize and essentialize a distinct early Christian social identity that was actually blurred and in the making.Peer reviewe

The NOvA Technical Design Report

This Technical Design Report (TDR) describes the preliminary design of the NOνA accelerator upgrades, NOνA detectors, detector halls and detector sites. Compared to the March 2006 and November 2006 NOνA Conceptual Design Reports (CDR), critical value engineering studies have been completed and the alternatives still active in the CDR have been narrowed to achieve a preliminary technical design ready for a Critical Decision 2 review. Many aspects of NOνA described this TDR are complete to a level far beyond a preliminary design. In particular, the access road to the NOvA Far Detector site in Minnesota has an advanced technical design at a level appropriate for a Critical Decision 3a review. Several components of the accelerator upgrade and new neutrino detectors also have advanced technical designs appropriate for a Critical Decision 3a review

Kinematic Evidence For Top-quark Pair Production In W Plus Multijet Events In P(p)over-bar Collisions At Root-s=1.8 Tev

We present a study of W+multijet events that compares the kinematics of the observed events with expectations from direct QCD W+jet production and from production and decay of top quark pairs. The data were collected in the 1992-93 run with the Collider Detector at Fermilab (CDF) from 19.3 pb-1 of proton-antiproton collisions at s =1.8 TeV. A W+2 jet sample and a W+3 jet sample are selected with the requirement that at least the two or three jets have energy transverse with respect to the beam axis in excess of 20 GeV. The jet energy distributions for the W+2 jet sample agree well with the predictions of direct QCD W production. From the W+3 jet events, a "signal sample" with an improved ratio of tt̄ to QCD produced W events is selected by requiring each jet to be emitted centrally in the event center of mass frame. This sample contains 14 events with unusually hard jet ET distributions not well described by expectations for jets from direct QCD W production and other background processes. Using expected jet ET distributions, a relative likelihood is defined and used to determine if an event is more consistent with the decay of tt̄ pairs, with Mtop=170 GeV/c2, than with direct QCD W production. Eight of the 14 signal sample events are found to be more consistent with top-quark than direct QCD W production, while only 1.7 such top-quark-like events are expected in the absence of tt̄. The probability that the observation is due to an upward fluctuation of the number of background events is found to be 0.8%. The robustness of the result was tested by varying the cuts defining the signal sample, and the largest probability for such a fluctuation found was 1.9%. Good agreement in the jet spectra is obtained if jet production from tt̄ pair decays is included. For those events kinematically more consistent with tt̄ we find evidence for a b-quark content in their jets to the extent expected from top quark decay, and larger than expected for background processes. For events with four or more jets, the discrepancy with the predicted jet distributions from direct QCD W production, and the associated excess of b-quark content, is more pronounced. © 1995 The American Physical Societ

Properties of jets in Z boson events from 1.8 TeV p\u304p collisions

We present a study of events with Z bosons and hadronic jets produced in p\uafp collisions at a center-of-mass energy of 1.8 TeV. The data consist of 6708 Z\u2192e+e 12 decays from 106pb 121 of integrated luminosity collected using the CDF detector at the Fermilab Tevatron Collider. The Z+ 65n jet cross sections and jet production properties have been measured for n=1 to 4. The data are compared to predictions of leading-order QCD matrix element calculations with added gluon radiation and simulated parton fragmentation

Measurement of the \u3b3 + D*\ub1 cross section in p\u304p collisions at 1as = 1.8 TeV

We have measured the cross section of gamma + D-*+/- production in <(p)over bar p> collisions at root s = 1.8 TeV using the Collider Detector at Fermilab. In this kinematic region, the Compton scattering process (g(c) --> gamma(c)) is expected to dominate and thus provide a direct link to the charm quark density in the proton. From the 45 +/- 18 gamma + D-*+/- candidates in a 16.4 pb(-1) data sample, we have determined the production cross section to be 0.38 +/- 0.15(stat) +/- 0.11(syst) nb for the rapidity range y(D-*+/-) < 1.2 and y(gamma) < 0.9, and for the transverse momentum range p(T)(D-*+/-) > 6 GeV/c and 16 < p(T)(gamma) < 40 GeV/c. The measured cross section is compared to a theoretical prediction
