The search is motivated by an excess of electron-like events in the 200–475 MeV energy region as reported by the MiniBooNE experiment. In NOMAD, photons are identified via their conversion to e+e− in an active target embedded in a magnetic field. The background to the single photon signal is dominated by the asymmetric decay of neutral pions produced either in a coherent neutrino–nucleus interaction, or in a neutrino–nucleon neutral current deep inelastic scattering, or in an interaction occurring outside the fiducial volume. All three backgrounds are determined in situ using control data samples prior to opening the ‘signal-box’. In the signal region, we observe 155 events with a predicted background of 129.2±8.5±3.3. We interpret this as null evidence for excess of single photon events, and set a limit. Assuming that the hypothetical single photon has a momentum distribution similar to that of a photon from the coherent π0 decay, the measurement yields an upper limit on single photon events, <4.0×10−4 per νμ charged current event. Narrowing the search to events where the photon is approximately collinear with the incident neutrino, we observe 78 events with a predicted background of 76.6±4.9±1.9 yielding a more stringent upper limit, <1.6×10−4 per νμ charged current event.
Publication Media Consume Tokyo: Television and Urban Place Since the Bubble
(2016-05-18) Bueno, Alex; Blau, Eve; Lippit, Yukio; Sand, JordanMuch has been made of the proliferation of fictions in the contemporary city, coming together under the hegemony of globalization to obliterate the particularities of place. The pervasiveness of media in daily life gives the impression of inescapability, and it appears impossible to conceive of the city in “traditional” physical terms. Among the nations of the so-called First World, Japan, the center of which is unquestionably the metropolis of Tokyo, has been at the fore of the social, economic and technological changes that revel in these fictions.
This dissertation is a critique of the culture of Tokyo of the last several decades. Following from the assumption that the city and mass media are inseparable, it examines the representations of urban places in television towards understanding how they function as part of urban development. It is thus an attempt at a history of urban culture incorporating both “concrete” and “virtual” forms of spatial practice, towards a unified understanding of the processes that create the contemporary city, with a particular focus on the role of corporations.
Two specific places in Tokyo that underwent large-scale development have had an exceptional presence in Japanese television: Odaiba and Akihabara. Limited to two types of television, what are known in Japan as “trendy dramas” and anime (animated cartoons), this dissertation examines the roles television programming had in creating or recreating the “placeness” of these two parts of Tokyo. It is separated into two parts for each location. Chapters one and three examine the historical background of each place alongside the media context that applies in each case, and chapters two and four demonstrate how television was used to advertise a particular image of each place.
