Study of neutrino induced upgoing muon energy
نویسنده
چکیده
An estimate of the energy of neutrino-induced muons in MACRO is provided by a multiple Coulomb scattering measurement. The MACRO original upward-muon data sample has been subdivided according to the reconstructed muon energy. The results are interpreted in terms of neutrino oscillation

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...
متن کاملSearch for High Energy Neutrino Emission from Gamma - Ray Bursts
The photo-meson production of pions by shock-accelerated protons could generate a burst of ∼ 10 14 eV neutrinos from gamma-ray bursts (GRBs) observable in the Antarctic Muon and Neutrino Detector Array (AMANDA) or its larger successors. Measurement of this flux can test the hypothesis that GRBs are the sources of the highest-energy cosmic rays, and GRB neutrinos could permit high-precision expe...
متن کاملUse of Coulomb scattering for determining neutrino energies with MACRO
An estimate of the energy of neutrino-induced muons in MACRO is provided by a multiple Coulomb scattering measurement. The MACRO original upward-muon data sample has been subdivided according to the reconstructed muon energy. Data in each subset are then compared with expected fluxes from atmospheric neutrinos. The results are interpreted in terms of neutrino oscillations.
متن کاملTeV photons and Neutrinos from giant soft-gamma repeaters flares
During the last 35 years three giant flares were observed from so-called Soft Gamma Repeaters (SGR’s). They are assumed to be associated with star-quakes of pulsars accelerating electrons and, possibly, protons to high energy in the huge magnetic fields as inferred from the observations. Because of this and the observation of non-thermal emission it has been speculated that they may be cosmic r...
متن کاملNeutrino Physics and Astronomy with Macro
MACRO experiment operated in the Gran Sasso underground laboratory. Neutrino events collected by this detector are used in order to study the atmospheric neutrino flux. Different measurements in different energy samples are in full agreement and show evidence of neutrino oscillation phenomenon with maximal mixing and ∆m 2 ∼ 0.0025 eV 2. Also the search for neutrino astrophysical sources is repo...
