چکیده

This letter presents a combined measurement of the energy spectra atmospheric $\nu_e$ and $\nu_\mu$ in range between $\sim$100 GeV $\sim$50 TeV with ANTARES neutrino telescope. The analysis uses 3012 days detector livetime period 2007--2017, selects 1016 neutrinos interacting (or close to) instrumented volume detector, yielding shower-like events (mainly from $\nu_e+\overline \nu_e$ charged current plus all neutral interactions) starting track $\nu_\mu + \overline \nu_\mu$ interactions). contamination by muons final sample is suppressed at level few per mill different steps selection analysis, including Boosted Decision Tree classifier. distribution reconstructed unfolded terms electron muon fluxes. derived are compared previous measurements that, above 100 GeV, limited to experiments polar ice and, for $\nu_\mu$, Super-Kamiokande.

Comparing and contrasting the ν μ → ν τ and ν μ → ν s solutions to the atmospheric neutrino problem with SuperKamiokande data

The νμ → ντ and νμ → νs solutions to the atmospheric neutrino problem are compared with SuperKamiokande data. The differences between these solutions due to matter effects in the Earth are calculated for the ratio of μ-like to e-like events and for up-down flux asymmetries. These quantities are chosen because they are relatively insensitive to theoretical uncertainties in the overall neutrino f...

The ANTARES Neutrino Telescope

The ANTARES underwater neutrino telescope, at a depth of 2475 m in the Mediterranean Sea, near Toulon, is taking data in its final configuration of 12 detection lines. Each line is equipped with 75 photomultipliers (PMT) housed in glass pressure spheres arranged in 25 triplets at depths between 100 and 450 m above the sea floor. The PMTs look down at 45 to have better sensitivity to the Cherenk...

Measuring the ν μ to ν μ Ratio in a High Statistics Atmospheric Neutrino Experiment

By exploiting differences in muon lifetimes it is possible to distinguish ν µ from ν µ charged current interactions in underground neutrino detectors. Such observations would be a useful tool in understanding the source of the atmospheric neutrino anomaly.

Measurement of the atmospheric ν μ spectrum with IceCube 59

The energy spectrum of the atmospheric muon neutrino flux was measured with the IceCube detector in the 59-string configuration, using an unfolding procedure. This measurement extended IceCube’s reach for atmospheric neutrinos up to 1PeV in energy. This extension in energy was obtained by using a machine learning algorithm preceeded by a dedicated feature selection for event selection, and by a...

Neutrino Mass Spectrum with ν μ → ν s Oscillations of Atmospheric Neutrinos

We consider the " standard " spectrum of the active neutrinos (characterized by strong mass hierarchy and small mixing) with additional sterile neutrino, ν s , which mixes strongly with muon neutrino, so that ν µ ↔ ν s oscillations solve the atmospheric neutrino problem. The parametric enhancement of the ν µ ↔ ν s oscillations occurs for the high energy atmospheric neutrinos which cross the cor...
