The ANTARES and Km3net Neutrino Telescopes: Status and Outlook for Acoustic Studies
EPJ Web of Conferences 216, 01004 (2019) https://doi.org/10.1051/epjconf/201921601004 ARENA 2018 The ANTARES and KM3NeT neutrino telescopes: Status and outlook for acoustic studies Véronique Van Elewyck1,2, for the ANTARES and KM3NeT Collaborations 1APC, Université Paris Diderot, CNRS/IN2P3, CEA/Irfu, Observatoire de Paris, Sorbonne Paris Cité, France 2Institut Universitaire de France, 75005 Paris, France Abstract. The ANTARES detector has been operating continuously since 2007 in the Mediterranean Sea, demonstrating the feasibility of an undersea neutrino telescope. Its superior angular resolution in the reconstruction of neutrino events of all flavors results in unprecedented sensitivity for neutrino source searches in the southern sky at TeV en- ergies, so that valuable constraints can be set on the origin of the cosmic neutrino flux discovered by the IceCube detector. The next generation KM3NeT neutrino telescope is now under construction, featuring two detectors with the same technology but different granularity: ARCA designed to search for high energy (TeV-PeV) cosmic neutrinos and ORCA designed to study atmospheric neutrino oscillations at the GeV scale, focusing on the determination of the neutrino mass hierarchy. Both detectors use acoustic devices for positioning calibration, and provide testbeds for acoustic neutrino detection. 1 Introduction Neutrinos have long been proposed as a complementary probe to cosmic rays and photons to explore the high-energy (HE) sky, as they can emerge from dense media and travel across cosmological dis- tances without being deflected by magnetic fields nor absorbed by inter- and intra-galactic matter and radiation. HE (>TeV) neutrinos are expected to be emitted in a wide range of astrophysical objects. -

The Outer Detector (OD) system for the Hyper-Kamiokande experiment PoS(ICHEP2020)886 Stephane Zsoldos0,1,2,∗ 0Department of Physics, King’s College London, Strand, London WC2R 2LS, United Kingdom 1Department of Physics, University of California, Berkeley, CA 94720, Berkeley, USA 2Lawrence Berkeley National Laboratory, 1 Cyclotron Road, Berkeley, CA 94720-8153, USA E-mail: [email protected], [email protected] Hyper-Kamiokande, scheduled to begin construction as soon as 2020, is a next generation under- ground water Cherenkov detector, based on the highly successful Super-Kamiokande experiment. It will serve as a far detector, 295 km away, of a long baseline neutrino experiment for the upgraded J-PARC beam in Japan. It will also be a detector capable of observing — far beyond the sensitivity of the Super-Kamiokande detector — proton decay, atmospheric neutrinos, and neutrinos from astronomical sources. An Outer Detector (OD) consisting of PMTs mounted behind the inner detector PMTs and facing outwards to view the outer shell of the cylindrical tank, would provide topological information to identify interactions originating from particles outside the inner detector. Any optimization would lead to a significant improvement for the physics goals of the experiment, which are the measurement of the CP leptonic phase and the determination of the neutrino mass hierarchy. An innovative new setup using small 3" PMTs is being proposed for the Hyper-Kamiokande OD. They would give better redundancy, spatial, and angular resolution, as there would be twice or three times more photosensors that the original 8" design proposal of the experiment, and for a reduced cost. -

This rapporteur report builds on 212 contributions with pre-recorded talks and posters, as well as 11 discussion sessions. Furthermore, many of the session conveners provided valuable input to this summary. 37th International Cosmic Ray Conference (ICRC 2021) July 12th – 23rd, 2021 Online – Berlin, Germany ∗Presenter © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0). https://pos.sissa.it/ Rapporteur: Neutrinos and Muons Anna Nelles The field of neutrino astronomy already provides exciting results, however,it is still dominated by very low statistics in astrophysical neutrino detections. The most transformative results have been discussed in the multi-messenger context [1] and clearly neutrinos are becoming a target of opportunity for all experiments with a potential sensitivity to them. The neutrino field itself is booming with new ideas for detectors and has reached a maturity in which detailed data analysis and systematic detector calibration are the order of business. To summarize the sentiment: the community is doing their homework to get ready for many more neutrinos, which the broader community is excited about.
