We report the measurement of the time of flight of ∼17 GeV ν(μ) on the CNGS baseline (732 km) with the Large Volume Detector (LVD) at the Gran Sasso Laboratory. The CERN-SPS accelerator has been operated from May 10th to May 24th 2012, with a tightly bunched-beam structure to allow the velocity of neutrinos to be accurately measured on an event-by-event basis. LVD has detected 48 neutrino events, associated with the beam, with a high absolute time accuracy. These events allow us to establish…

Precision measurement of the neutrino velocity with the ICARUS detector in the CNGS beam
A bstractDuring May 2012, the CERN-CNGS neutrino beam has been operated for two weeks for a total of ~1.8 × 1017 p.o.t., with the proton beam made of bunches, few ns wide and separated by 100 ns.
Measurement of the neutrino velocity with the OPERA detector in the CNGS beam using the 2012 dedicated data
A bstractIn spring 2012 CERN provided two weeks of a short bunch proton beam dedicated to the neutrino velocity measurement over a distance of 730 km. The OPERA neutrino experiment at the underground
Precision measurement of the speed of propagation of neutrinos using the MINOS detectors
We report a two-detector measurement of the propagation speed of neutrinos over a baseline of 734 km. The measurement was made with the NuMI beam at Fermilab between the near and far MINOS detectors.
Three flavour neutrino oscillations in MINOS
MINOS+ is an extension of the MINOS long-baseline neutrino experiment. It makes measurements of the upgraded NuMI neutrino beam at two detectors: the Near Detector, 1 km from the beam at Fermilab,
Long-Baseline Neutrino Oscillation Experiments
A review of accelerator long-baseline neutrino oscillation experiments is provided, including all experiments performed to date and the projected sensitivity of those currently in progress.
The Large Volume Detector (LVD) has been continuously taking data since 1992 at the INFN Gran Sasso National Laboratory. The LVD is sensitive to neutrino bursts from gravitational stellar collapses
Characterization of the varying flux of atmospheric muons measured with the Large Volume Detector for 24 years
The Large Volume Detector (LVD), hosted in the INFN Laboratori Nazionali del Gran Sasso, is triggered by atmospheric muons at a rate of $\sim 0.1$~Hz. The data collected over almost a quarter of
Neutrino Velocity and the Variability of Fundamental Constants
Neutrino speed experiments could be viewed not only as tests of Lorentz invariance but also as measurements of limiting propagation speed for all standard model species below certain depth where no
Decay kinematics in the aether: Pion decay, kaon decay, and superluminal Cherenkov radiation
Pion and kaon decay, π → μ + νμ, K → μ + νμ, into muons and GeV neutrinos is investigated with regard to a possible superluminal neutrino speed. Photonic Cherenkov emission by superluminal
Evaluation of the OPERA Collaboration and theFaster than Light Neutrino Anomaly
On 22 September 2011 the OPERA collaboration published a paper which communicated their results concerning the measurement of the neutrino velocity, which appeared to have exceeded the speed of
