KM3NeT/ORCA is a neutrino detector optimised for measuring atmospheric neutrinos from a few GeV to around 100 GeV. In this paper, the sensitivity of the KM3NeT/ORCA detector to neutrino decay has been explored. A three-flavour neutrino oscillation scenario, where the third neutrino mass state v3 decays into an invisible state, e.g. a sterile neutrino, is considered. We find that KM3NeT/ORCA would be sensitive to invisible neutrino decays with 1/alpha 3 = T3/m3 < 180 ps/eV at 90% confidence level, assuming true normal ordering. Finally, the impact of neutrino decay on the precision of KM3NeT/ORCA measurements for theta(23), Delta m(31)(2) and mass ordering have been studied. No significant effect of neutrino decay on the sensitivity to these measurements has been found.}, organization = {Commission Européenne FEDER fund}, organization = {Commission Européenn Marie Curie Program}, organization = {MCIN/AEI/ 10.13039/501100011033, ID2021-124591NB-C41, -C42, -C43}, organization = {ERDF}, organization = {European Union}, organization = {European Union NextGenerationEU/PRTR}, organization = {Planes Complementarios I+D+I, ASFAE/2022/023, ASFAE/2022/014}, organization = {PROMETEO/2020/019}, organization = {Generalitat Valenciana, GenT, CIDEGENT/2018/034, /2019/043, /2020/049, /2021/23}, organization = {Junta de Andalucía SOMM17/6104/UGR, P18-FR-5057}, organization = {EU: MSC program 101025085}, organization = {European Union, NextGenerationEU, Programa María Zambrano}, publisher = {Springer Nature}, keywords = {Beyond Standard Model}, keywords = {Neutrino Detectors and Telescopes (experiments)}, keywords = {Oscillation}, title = {Probing invisible neutrino decay with KM3NeT/ORCA}, doi = {10.1007/JHEP04(2023)090}, author = {The KM3NeT collaboration and Aiello, S. and Gutiérrez González, Miguel and Navas Concha, Sergio and Anguita López, Mancia and Díaz García, Antonio Francisco}, }
