From their role in the mechanism through which Standard Model (SM) neutrinos acquire mass, to their potential explanation of anomalies in oscillation experiments and even as Dark Matter candidates, these hypothetical particles are thought to play a central part in the near future of particle physics. Many models of sterile neutrinos exist, in some of which they are allowed to decay to SM particles. If the sterile neutrino production and subsequent decay happens inside the IceCube detector, this would lead to a double-cascade signature similar but not identical to the one known from tau neutrino charged current interactions. However, the lifetime of the sterile neutrino is potentially much longer than that of the tau lepton, depending on its mass. This opens the possibility for a spatial resolution of a double cascade topology at atmospheric neutrino energies, as opposed to searches for high energy tau neutrinos from astrophysical sources. We present the results of a first study of the IceCube-DeepCore detector sensitivity to such a signal. The strategy is to study the topology of such double-cascade events in simulation and design a classifier that helps us isolate a sample of signal events over the background from SM processes. We study the sensitivity as a function of the signal parameters to determine in what conditions could IceCube see such a signal. Scanning the two-dimensional tau-sterile mixing parameter and sterile neutrino mass phase-space, we conclude that with the current state of the analysis, this search will have to wait for the IceCube Upgrade or a major improvement in the analysis tools in order for a signal to be isolated from the very large neutrino background.","PeriodicalId":135659,"journal":{"name":"Proceedings of Particles and Nuclei International Conference 2021 — PoS(PANIC2021)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128424625","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 objective of this work is to develop simulation tools that allow a better understanding of radiobiology results obtained in cell irradiation studies in the presence of multi-functional nanoparticles. In these proceedings we summarize the methodology that is being developed to make realistic simulations of the irradiation of monolayer and spheroid human glioblastomas multiforme cell cultures, taking into consideration diﬀerent concentrations of the gold nanoparticles. Based on these simulations, microdosimetric dose distributions will be obtained as well as the temporal distribution of G-values yields for diﬀerent reactive oxygen species. The microdosimetric distributions in cells will be used to predict cell survival fractions, using mathematical models of the biological eﬀects of radiation. The results obtained in the simulations will be compared with the biological in vitro and in vivo experimental results.","PeriodicalId":135659,"journal":{"name":"Proceedings of Particles and Nuclei International Conference 2021 — PoS(PANIC2021)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132436814","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}
