Study of neutrino interactions with the electronic detectors of the OPERA experiment
No full textThe OPERA experiment is based on a hybrid technology
combining electronic detectors (EDs) and nuclear emulsions. OPERA collected muon–neutrino interactions during the 2008 and 2009 physics runs of the CNGS neutrino beam, produced at CERN with an energy range of about 5–35 GeV. A total of 5.3×1019 protons on target equivalent luminosity have been analysed with the OPERA EDs: scintillator strips target trackers and magnetic muon spectrometers equipped with resistive plate gas chambers and drift tubes, allowing a detailed reconstruction of muon–neutrino interactions
Phenomenology of Philosophy of Science: OPERA data
No full textI observe that,
as the physics side of the OPERA-anomaly story is apparently unfolding,
there can still be motivation for philosophy of science to analyze
the six months of madness physicists spent chasing the dream of a new
fundamental-physics revolution.
I here mainly report data on studies of the OPERA anomaly
that could be relevant for analyses from the
perspective of phenomenology of philosophy of science.
Most of what I report is an insider's perspective on
the debate that evolved from the original announcement
by the OPERA collaboration of evidence of superluminal neutrinos.
I also sketch out, from a broader perspective,
some of the objectives I view as achievable for
the phenomenology of philosophy of science

OPERA status report (SPSC 97)
No full textThis document updates the status of OPERA after the last SPSC report of June 2009. The report presents the progress of the various subsystems and informs about the recent start of the 2010 run. In particular, we focus on the analysis steps that go from the prediction of where the neutrino interaction occurred down to the decay search procedure and the following kinematical analysis. The analysis of the first OPERA tau candidate event is not discussed here, since details can be found in a paper accepted for publication on Physics Letters B and attached to this report
The OPERA Experiment: Latest Results
No full textThe long-baseline neutrino oscillation experiment OPERA has been designed for the direct observation of appearance in the CNGS beam.The OPERA detector is located at the LNGS underground laboratory, with a distance of from the neutrino source at CERN. It is a hybrid detector, combining the micrometric precision of emulsion cloud chambers with electronic detector elements for online readout.While CNGS beam data taking lasted from 2008 to 2012, the neutrino oscillation analysis is still ongoing. Updated results with increased statistics are presented, including the recent observation of appearance at
The Structure of Scientific Collaboration Networks in Scientometrics
No full textThe structure of scientific collaboration networks in scientometrics was investigated at the level of individuals by using bibliographic data of all papers published in the international journal Scientometrics retrieved from the Science Citation Index (SCI) during 1978 to 2004. Combined analysis of social network analysis (SNA), co-occurrence analysis, cluster analysis and frequency analysis of words was explored to reveal: (1) The microstructure of the collaboration network on scientists’ aspects of scientometrics; (2) The major collaborative fields of the collaborative sub-networks; (3) The collaborative center of the collaboration network in scientometrics
