“…Dedicated MC simulations have been generated with modified OM photon detection efficiencies and a modified water absorption length, assuming a variation of ±10% from the nominal value, but keeping the same wavelength dependence. The overall OM efficiency can be easily adjusted to the measured coincidence rates from 40 K decays [22] which makes the chosen 10% variations a conservative benchmark value, in line with early studies performed on ANTARES OMs [17]. The water absorption length had been measured several times at the ANTARES site [35].…”

The ANTARES neutrino telescope has an energy threshold of a few tens of GeV. This allows to study the phenomenon of atmospheric muon neutrino disappearance due to neutrino oscillations. In a similar way, constraints on the 3+1 neutrino model, which foresees the existence of one sterile neutrino, can be inferred. Using data collected by the ANTARES neutrino telescope from 2007 to 2016, a new measurement of ∆m 2 32 and θ 23 has been performed -which is consistent with world best-fit values -and constraints on the 3+1 neutrino model have been derived.

“…These samples are directly used as input for the background light simulation. Thirdly, individual OM efficiencies are considered, as calculated on an approximately weekly basis from 40 K coincidence rates [22]. Finally, the acoustics based position calibration, performed every few minutes, is applied.…”

The STRings for Absorption length in Water (STRAW) experiment is the first in a series of pathfinder missions for the Pacific Ocean Neutrino Experiment (P-ONE), a future large-scale neutrino telescope in the north-eastern Pacific Ocean. STRAW consists of two 150 m long mooring lines instrumented with optical emitters and detectors. The experiment is designed to measure the attenuation length of the water and perform a long-term assessment of the optical background at the future P-ONE site. After two years of continuous operation, measurements from STRAW show an optical attenuation length of about 28 metres at 450 nm. Additionally, the data allows a study of the ambient undersea background. The overall optical environment reported here is comparable to other deep-water neutrino telescopes and qualifies the site for the deployment of P-ONE.
