Available in PDF, EPUB and Kindle. Book excerpt: Currently, the clearest evidence for physics beyond the Standard Model is provided by observations that indicate non-zero neutrino masses. Numerous theories on how these masses are generated give rise to additional non-standard interactions (NSI) of neutrinos with quarks and charged leptons. Atmospheric neutrinos provide a sensitive probe for the neutrino flavor transitions resulting from the type of NSI investigated in this work. These comprise neutral current forward scattering of neutrinos of all flavors on first generation charged fermions in Earth matter. In order to maximize model independence, the NSI are parametrized using five effective coupling strengths. In the IceCube-DeepCore detector, atmospheric neutrinos are detected indirectly via Cherenkov photons produced within the Antarctic glacier. The range of angles under which neutrinos enter the detector translates into propagation baselines of O(1 - 10000 )km. The data sample used in the presented analysis includes 9.3 years of DeepCore data, covering a neutrino energy range of 5 to 100 GeV. Accuracy and performance of event property reconstruction from observed photons are a crucial factor for the analysis outcome. Therefore, this work includes a thorough study of the potential and shortcomings of likelihood based DeepCore event reconstruction algorithms. The presented analysis relies on comparing binned observed event counts to simulation that is generated at different hypotheses. These include the individually considered NSI parameters as well as 17 nuisance parameters. In order to find the hypothesis that best describes the observation, the optimum of a test statistic is determined using a customized minimization strategy. The final analysis setup yields sensitivities to four effective NSI couplings that are competitive compared with existing results.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For decades, the Standard Model of Particle Physics has stood the test of time, being one of the most comprehensive and reliable models ever proposed. One of the few exceptions to its robustness was the discovery of neutrino oscillations (and consequently the implication that neutrinos have mass). It is one of the only confirmed pieces of evidence of physics beyond the Standard Model. Since this discovery, there has been a worldwide effort on both the theoretical and experimental fronts to answer many questions that this discovery raised. Many neutrino experiments around the world seek to measure the model parameters that describe these oscillations within the current theoretical 3 neutrino framework. The IceCube Neutrino Observatory is a kilometer-scale detector embedded in the Antarctic ice at the South Pole and detects Cherenkov light produced by neutrinos interacting in the ice. DeepCore is a densely instrumented sub-array within the full detector that observes interactions of atmospheric neutrinos down to 5 GeV. At these energies, Earth-crossing muon neutrinos have a high chance of oscillating to tau neutrinos. DeepCore is able to measure these oscillations with precision comparable to accelerator-based experiments, but it is also complementary to accelerator measurements because it probes longer distance scales and higher energies, peaking above the tau lepton production threshold. This dissertation presents the effort involved in curating one of the largest neutrino oscillation datasets in the world, with over 200,000 events spanning almost 10 years (from April 2012 to January 2022) and a neutrino purity of over 99%. This sample is optimized for performing a measurement of the atmospheric neutrino oscillation parameters. The nearly unprecedented level of statistics also requires unprecedented precision in the treatment of systematic uncertainties. Compared to previous DeepCore analyses, this analysis benefits from improved background rejection, new simulation, a new reconstruction, a new machine learning particle classification algorithm, improved modeling of systematic uncertainties, and more years of data. Given the large number of changes compared to previous analyses, an extensive suite of quality and robustness checks were performed. Even with the extensive testing program, our fit to data informed us that our modeling is not yet on par with the level of statistical precision achieved with the new sample; the goodness-of-fit between our data and simulation yielded a p-value of 0[percent]. At the time of writing, there remains an ongoing effort to improve our models to describe the full dataset. This dissertation includes the unblinded results of an analysis performed with a sub-sample containing 20[percent] of the full dataset.

This book was released on 2019-12-23 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the reader to how fundamental topics in particle physics can be studied with the largest neutrino telescopes currently in operation. Due to their large size, reaching cubic-kilometer volumes, and their wide energy response, these unusual detectors can provide insight on neutrino oscillations, dark matter searches or searches for exotic particles, new neutrino interactions or extra dimensions, among many other topics.Lacking a man-made neutrino 'beam', neutrino telescopes use the copious flux of neutrinos continuously produced by cosmic rays interacting in the Earth's atmosphere, as well as neutrinos from astrophysical origin. They have therefore access to neutrinos of higher energies and much longer baselines than those produced in present accelerators, being able to search for new physics at complementary scales than currently available in particle physics laboratories around the world.Written by carefully chosen experts in the field, the book introduces each topic in a pedagogical way apt not only to professionals, but also to students or the interested reader with a background in physics.

Available in PDF, EPUB and Kindle. Book excerpt: The IceCube detector at the South Pole is a cubic-kilometer-scale neutrino detector designed to observe TeV-range charged particle secondaries from neutrino interactions, and thus do neutrino astronomy. As a main background to the search for astrophysical point sources of neutrinos, IceCube also observes muons and neutrinos from the atmospheric interactions of cosmic rays. By observing a spectrum of atmospheric neutrinos and comparing it to independent predictions of atmospheric fluxes with and without oscillations, IceCube can test various values of oscillation parameters. Neutrino oscillations have been observed experimentally for several decades; IceCube is the first experiment to extend this measurement to the 10-20 GeV energy range. An initial analysis has established that IceCube can see oscillations using the 79-string detector configuration ("IC79"), which was the first year of data that included the DeepCore detector. As a follow-up, this analysis uses a less restrictive event selection and thus a higher total event count, around 3,000 for one year of data. The fit is a Poisson likelihood fit of a two-dimensional rate histogram, using both oscillated length and observed energy. The arrival zenith angle of the muon is used as a proxy for oscillation length. The error contours are dominated by systematic effects more than by statistical limitations of the data. Major systematics include uncertainties in the atmospheric neutrino flux at high energies and uncertainties in the distribution of the cosmic ray muon background. This analysis was designed to produce limits on the mixing angle &theta23 that are competitive with other current experiments, although this is still uncertain as error analysis work is ongoing. Future work will further refine the event selection and systematic error analysis; the statistical methods and software used here are expected to become the IceCube oscillations standard. This thesis also includes background information about the history of neutrino physics, basics of oscillation formalism, and the IceCube DeepCore detector. A brief chapter is included on the search for a deficit in cosmic ray muons from the direction of the Moon, and the implications of that deficit for the pointing resolution of IceCube.

Available in PDF, EPUB and Kindle. Book excerpt: The measurement of muon neutrino disappearance presentedhere was designed to make use of neutrinos of all flavors,exploiting $\nu_e$ events and more poorly reconstructedcascade-like neutrino events to better constrain systematicuncertainties associated with neutrino fluxes and interactions. Inaccordance with IceCube Collaboration policy, the analysis was developed "blind,'' with reference to Monte Carlo simulations and down-going events where no oscillation signal could be visible. Discrepancies observed in the data when they were examined after theanalysis was finalized led to the conclusion that the cascade-like and intermediate data samples were affected by unexpected systematiceffects, so that their inclusion in the analysis produced substantialbias. This analysis thus relied exclusively on the track-like data sample, while investigations into the nature of these systematic effects continue in preparation for an IceCubejournal article.The best fit and 68% confidence interval from this analysison the two oscillation parameters which drive muon neutrino disappearance are\begin{align*} \sin^2 \theta_{23} &= 0.53_{-0.11}^{+0.07}, \\ \Delta m_{32}^2 / 10^{-3}\mathrm{eV}^2 &= 2.35_{-0.17}^{+0.14},\end{align*}which are compatible and competitive with measurements madeby dedicated beam-line neutrino experiments.

Available in PDF, EPUB and Kindle. Book excerpt: Englische Version: Neutrino oscillations are the only phenomenon beyond the Standard Model that has been confirmed experimentally to a very high statistical significance. This work presents a measurement of atmospheric neutrino oscillations using eight years of data taken by the IceCube DeepCore detector between 2011 and 2019. The event selection has been improved over that used in previous DeepCore measurements with a particular emphasis on its robustness with respect to systematic uncertainties in the detector properties. The oscillation parameters are estimated via a maximum likelihood fit to binned data in the observed energy and zenith angle, where the expectation is derived from weighted simulated events. This work discusses the simulation and data selection process, as well as the statistical methods employed to give an accurate expectation value under variable detector properties and other systematic uncertainties. The measurement is first performed first under the standard three-flavor oscillation model, where the atmospheric mass splitting and mixing angle are estimated to be $\Delta m 2_{32} = 2.42_{-0.75} {+0.77} \times10 {-3}\;\mathrm{eV} 2$ and $\sin 2\theta_{23} = 0.507_{-0.053} {+0.050}$, respectively. The three-flavor model is then extended by an additional mass eigenstate corresponding to a sterile neutrino with mass splitting $\Delta m 2_{41} = 1\;\mathrm{eV} 2$ that can mix with the active $\nu_\mu$ and $\nu_\tau$ flavor states. No significant signal of a sterile neutrino is observed and the mixing amplitudes between the sterile and active states are constrained to $!U_{\mu 4}! 2
