ANTARES provides unprecedented sensitivity for neutrino source searches in the Southern Sky at TeV energies, so that valuable constraints can be set on the origin of the cosmic neutrinos discovered by the IceCube detector. ANTARES has also constrained the neutrino emission from possible Dark Matter annihilation in massive objects like the Sun or the Galactic Centre, and has measured the neutrino oscillation parameters in the atmospheric sector. Building on the ANTARES experience, KM3NeT, a new, much larger detector with improved design and technology is under construction on two sites in the Mediterranean sea. Deployed off the coast of Sicily, the ARCA telescope (Astroparticle Research with Cosmics in the Abyss) will be dedicated to the detection of high-energy astrophysical neutrinos. When completed, KM3NeT-ARCA detector with dimensions exceeding one kilometre cube, will reconstruct with an excellent angular resolution signatures of neutrinos of all flavors in a very clear deep-sea water environment. KM3NeT-ARCA, situated in the Northern hemisphere, will be able to observe up-going neutrinos from most of the Galactic Plane, making it possible to study the neutrino fluxes from different astrophysics sources, as well as neutrinos from Dark Matter annihilation. The latest results from ANTARES and the perspectives of the KM3NeT-ARCA detector will be presented.","PeriodicalId":322602,"journal":{"name":"Proceedings of The 21st international workshop on neutrinos from accelerators — PoS(NuFact2019)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130025158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This interest is guided by the experimental effort that aims at measuring the CP-violating phase by looking for electron (anti-)neutrino appearance in muon neutrino beams. In long-baseline experiments such as T2K, models for the neutrino cross section are often constrained by near-detector data, with a muon neutrino flux that is unoscillated. Non-trivial differences between electron and muon neutrino cross sections are currently experimentally not well constrained, and different models give varying results, especially in kinematic regions where nuclear structure details become important, i.e. for low energy and momentum transfers. In this work we present the nuclear response and cross section using different nuclear models, for forward lepton scattering in the region of a couple 100 MeVs. In this kinematic region the cross section is sensitive to nuclear structure details which are not accounted for in simplified models such as the relativistic Fermi gas (RFG) which is commonly used in the experimental analysis. The results show that it is important for current and future accelerator-based experiments, notably T2K and the short-baseline oscillation program (i.e the MicroBooNE, SBND and ICARUS experiments) which are sensitive to the several 100 MeV region, to take nuclear structure details into account in their analysis.","PeriodicalId":322602,"journal":{"name":"Proceedings of The 21st international workshop on neutrinos from accelerators — PoS(NuFact2019)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134626527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The next-generation Hyper-Kamiokande experiment will build on this with much higher statistics, enabling precision tests of the Standard PMNS picture. In the baseline design of 2 tanks at Kamioka, a detailed investigation of oscillations can be made in the vicinity of the first oscillation maximum, and at short baselines using the near detector. More interesting tests can be preformed if the second tank is located in Korea, as this give access to an $L/E$ regime that is three times higher than any previous long-baseline experiment. As well as benefits to the PMNS measurements, a new experimental regime makes it possible to resolve BSM models which are statistically degenerate on a single baseline.
