Based on the developed cross-correlation theory for remote location of neutrino source with two-detector setup for neutrino detection the modification of arrangement of the OPERA experiment is suggested. Within the framework of computing…
The OPERA experiment reached its main goal by proving the appearance of $\nu_{\tau}$ in the CNGS $\nu_{\mu} $ beam. A sample of five $\nu_{\tau}$ candidates was collected allowing to reject the null hypothesis at $5.1 \sigma$. The…
The OPERA neutrino experiment at the underground Gran Sasso Laboratory recently reported, in arXiv:1109.4897v1, high-accuracy velocity measurements of neutrinos from the CERN CNGS beam over the 730 km distance between the two laboratories.…
We discuss two experiments ICANOE and OPERA that have been proposed within the context of long-baseline and atmospheric neutrino experiments in Europe. The joint ICANOE/OPERA program aims at further improving our understanding of the effect…
The OPERA experiment was designed to search for $\nu_{\mu} \rightarrow \nu_{\tau}$ oscillations in appearance mode, i.e. by detecting the $\tau$-leptons produced in charged current $\nu_{\tau}$ interactions. The experiment took data from…
The LVD time stability allows to establish a time-shift in the OPERA experiment, thus providing the first proof against Superluminal neutrinos, using the horizontal muons of the "Teramo Anomaly". This proof is particularly interesting since…
The OPERA experiment, exposed to the CERN to Gran Sasso $\nu_\mu$ beam, collected data from 2008 to 2012. Four oscillated $\nu_\tau$ Charged Current interaction candidates have been detected in appearance mode, which are consistent with…
The COBRA demonstrator, a prototype for a large-scale experiment searching for neutrinoless double beta-decay, was built at the underground laboratory Laboratori Nazionali del Gran Sasso (LNGS) in Italy. It consists of an array of 64…
A stream of weakly interacting massive particles (WIMPs) gravitationally scattered outwards within the Earth yields a delay, \delta t \simeq 60 ns, in good agreement with the results of the OPERA experiment. Conversely, the OPERA experiment…
The poster presented the OPERA experiment and the SPL-Fr\'{e}jus neutrino super beam project. OPERA (1) is an experiment willing to see tau neutrino appearance. The detector is described in section 2 and the expected results are given.…
The OPERA experiment discovered muon neutrino into tau neutrino oscillations in appearance mode, detecting tau leptons by means of nuclear emulsion films. The apparatus was also endowed with electronic detectors with tracking capability,…
The project of a large underground experiment (NOE) devoted to long baseline neutrino oscillation measurement is presented
In the OPERA experiment, superluminal propagation of neutrinos can occur if one of the neutrino masses is extremely small. However the effect only has appreciable amplitude at energies of order this mass and thus has negligible overlap with…
We study how much the unique ability of the OPERA experiment to directly detect \nu_\tau can help in probing new, non-standard contact interactions of the third family of neutrinos. We perform a combined analysis of future, high-statistics…
The OPERA collaboration reported [1] a measurement of the neutrino velocity exceeding the speed of light by 0.025%. For the 730 km distance from CERN in Geneva to the OPERA experiment an early arrival of the neutrinos of 60.7 ns is measured…
The recent publication in ArXiv of "Measurement of the neutrino velocity with the OPERA detector in the CNGS beam" has attracted many interest due to the possible theoretical or phenomenological interpretation of the results. A subtle…
The authors of the OPERA experiment [arXiv:1109.4897] claim that "the measurement indicates an early arrival time of CNGS muon neutrinos with respect to the one computed assuming the speed of light in vacuum". In this note we analyze the…
The debate on OPERA focused on two extremes: either "OPERA is wrong" or our formulation of the laws of physics needs a major overhaul. I here argue that some effort should be directed toward manifestations of laws that are already known,…
The OPERA detector, designed to search for $\nu_{\mu} \to \nu_{\tau}$ oscillations in the CNGS beam, is located in the underground Gran Sasso laboratory, a privileged location to study TeV-scale cosmic rays. For the analysis here presented,…
The OPERA experiment at the CNGS beam has observed muon to tau neutrino oscillations in the atmospheric sector. Based on this result new limits on the mixing parameters of a massive sterile neutrino may be set. Preliminary results of the…
