ICARUS+NESSiE: A proposal for short baseline neutrino anomalies with innovative LAr imaging detectors coupled with large muon spectrometers
Get PDFThe proposal for an experimental search for sterile neutrinos beyond the Standard Model with a new CERN-SPS neutrino beam is presented. The experiment is based on two identical LAr-TPC@?s followed by magnetized spectrometers, observing the electron and muon neutrino events at 1600 and 300 m from the proton target. This project will exploit the ICARUS T600, moved from LNGS to the CERN ''Far'' position. An additional 1/4 of the T600 detector will be constructed and located in the ''Near'' position. Two spectrometers will be placed downstream of the two LAr-TPC detectors to greatly complement the physics capabilities. Comparing the two detectors, in absence of oscillations, all cross sections and experimental biases cancel out. Any difference of the event distributions at the locations of the two detectors might be attributed to the possible existence of @n-oscillations, presumably due to additional neutrinos with a mixing angle sin^2(2@q_n_e_w) and a larger mass difference @Dm_n_e_w^2. The superior quality of the LAr imaging TPC, in particular its unique electron-@p_0 discrimination allows full rejection of backgrounds and offers a lossless @n_e detection capability. The determination of the muon charge with the spectrometers allows the full separation of @n_@m from anti-@n_@m and therefore controlling systematics from muon mis-identification largely at high momenta
SEARCH FOR NU/MU NU/E OSCILLATIONS IN THE NOMAD EXPERIMENT
No full textA search for νμ ↔ νe oscillations based on the 1995 collected by the NOMAD experiment is presented. The quality of event reconstruction allows to select a background free νe CC sample. Good agreement is obtained with respect to predictions, allowing to exclude the presence of a signal from νμ ↔ νe oscillations and to establish a limit on the amplitude of the oscillation sin2(2θ) ≤ 2. 10−3 in the high Δm2 region
A FAST TRIGGER PROCESSOR FOR LIMITED STREAMER TUBES
Get PDFAn electronic device has been realized which provides the total number of firing limited streamer tubes (LST) in different sectors as well as in the whole detector. These numbers are available a few microseconds after the read-out of the LST front-end electronics and can be used for trigger purposes
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
