Neutrino physics is nowadays receiving more and more attention as a possible source of information for the long-standing problem of new physics beyond the Standard Model. The recent measurement of the third mixing angle 13 in the standard mixing oscillation scenario encourages us to pursue the still missing results on leptonic CP violation and absolute neutrino masses. However, several puzzling measurements exist which deserve an exhaustive evaluation. Wewill illustrate the present status of the muon disappearance measurements at small / and the current CERN project to revitalize the neutrino field in Europe with emphasis on the search for sterile neutrinos. We will then illustrate the achievements that a double muon spectrometer can make with regard to discovery of new neutrino states, using a newly developed analysis.

  • New Physics with Neutrinos
    New Physics with Neutrinos Dissertation zur Erlangung des Grades \Doktor der Naturwissenschaften" am Fachbereich Physik, Mathematik und Informatik der Johannes Gutenberg-Universitat¨ in Mainz Mona Inge Dentler geboren in Munchen¨ Mainz, den 23.11.2018 Abstract Due to open problems in theory and unresolved anomalies in various oscilla- tion experiments, neutrino physics appears to be an excellent starting point in the quest for physics beyond the Standard Model (SM). The 3 + 1 framework featuring an additional, sterile neutrino mixing with the known neutrinos, is a minimalist extension of the SM which can account for oscillation phenomenology beyond the standard three flavor paradigm. However, two orthogonal arguments militate against this model. First, the increasing amount of ambiguous experimental results makes a con- sistent interpretation of the data in the 3 + 1 framework appear unlikely. In this regard, global fits provide a useful tool to investigate this objection. This thesis reports on the results of an up-to-date global fit to all relevant, available datasets, including the data corresponding to the reactor antineutrino anomaly (RAA), the gallium anomaly and the short baseline (SBL) anomaly. The reactor data as a special case can plausibly be explained by the hypothesis of a misprediction of the reactor antineutrino flux. Therefore, this hypothesis is tested against the 3 + 1 framework. Both hypotheses are found to be similarly likely, with a slight preference for the 3 + 1 framework, mainly driven by the data from DANSS and NEOS, which measure antineutrino spectra. However, a combination of both hypotheses fits the data best, with the hypothesis of a mere misprediction of the reactor flux rejected at 2:9σ.

    A Deep-Learning-Based a` CCQE Selection for Searches Beyond the Standard Model with MicroBooNE Davio Cianci Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy under the Executive Committee of the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2021 © 2021 Davio Cianci All Rights Reserved Abstract A Deep-Learning-Based a` CCQE Selection for Searches Beyond the Standard Model with MicroBooNE Davio Cianci The anomalous Low Energy Excess (LEE) of electron neutrinos and antineutrinos in MiniBooNE has inspired both theories and entire experiments to probe the heart of its mystery. One such experiment is MicroBooNE. This dissertation presents an important facet of its LEE investigation: how a powerful systematic can be levied on this signal through parallel study of a highly correlated channel in muon neutrinos. This constraint serves to strengthen MicroBooNE’s ability to confirm or validate the cause of the LEE and will lay the groundwork for future oscillation experiments in Liquid Argon Time Projection Chamber (LArTPC) detector experiments like SBN and DUNE. In addition, this muon channel can be used to test oscillations directly, demonstrated through the world’s first a` disappearance search with LArTPC data.

  • (3 + 1 )-Spectrum of Neutrino Masses: a Chance for LSND?

We atm sun introduce the parameters ηs and ηs which quantify an involvement of the sterile component + atm + sun = in the solar and atmospheric neutrino oscillations. The (2 2)-scheme predicts ηs ηs 1 and the experimental proof of deviation from this equality will discriminate the scheme. In this connection the (3 + 1)-scheme is revisited in which the fourth (predominantly sterile) neutrino 2 ∼ 2 is isolated from a block of three flavour neutrinos by the mass gap mLSND (0.4–10) eV . Wefindthatinthe(3 + 1)-scheme the LSND result can be reconciled with existing bounds on νe-andνµ-disappearance at 95–99% C.L. The generic prediction of the scheme is the νe- and νµ-disappearance probabilities at the level of present experimental bounds. The possibility to strengthen the bound on νµ-disappearance in the KEK — front detector experiment is studied.

Perelstein2 1 School of Natural Sciences, Institute for Advanced Study, Princeton, NJ 08540 e-mail: a [email protected], b [email protected] 2 Theoretical Physics Group, Lawrence Berkeley National Laboratory, Berkeley, CA 94720 e-mail: [email protected] Abstract The existence of bulk sterile neutrinos in theories with large extra dimen- sions can naturally explain small 4-dimensional Dirac masses for the active neutrinos. We study a model with 3 bulk neutrinos and derive various con- straints on the size of the extra dimensions from neutrino oscillation experi- ments. Our analysis includes recent solar and atmospheric data from SNO and arXiv:hep-ph/0201128v2 23 Jan 2002 Super-Kamiokande, respectively, as well as various reactor and accelerator ex- periments. In addition, we comment on possible extensions of the model that could accommodate the LSND results, using natural parameters only. Our most conservative bound, obtained from the atmospheric data in the hierar- chical mass scheme, constrains the largest extra dimension to have a radius R < 0.82 µm. Thus, in the context of the model studied here, future gravita- tional experiments are unlikely to observe the effects of extra dimensions. ∗Permanent address: Department of Physics and Astronomy, University of Pennsylvania, Philadelphia, PA 19104. 1 Introduction The substantial body of theoretical work done on models with Large Extra Dimensions (LED’s) has provided us with new insights on some old problems. Even though the original motivations were mostly related to the question of gauge hierarchy [1], various other applications have been found and studied.

  • Neutrino Physics
    Neutrino Physics • The beginning: beta decay crisis: violation of energy conservation? • Wolfgang Pauli proposes the neutrino; Enrico Fermi formulates the theory of nuclear beta decay. • Is the antineutrino identical with the neutrino? • Detection of the neutrino: the Reines-Cowan experiment. • Muon decay crisis: one or two types of neutrinos? • The two-neutrino experiment. • The third lepton generation; detection of the tau neutrino. HEP: Neutrino Physics I 1 Beta decay crisis: violation of energy conservation? In the early years of studying nuclear beta decay it was wrongly assumed that the beta decay reaction had the form of ( A,,1ZAZe) →++( ) − Then the electron should have a momentum given by 1 22 pMmmMmm=−−−+⎡ 22⎤⎡ ⎤ 2M ⎣⎢ ()12⎦⎣⎥⎢ ()12⎦⎥ with M=M(A,Z), m1=M(A,Z+1) and m2=me The particular value of some specific beta decay is not important. Important is that the momentum, and hence the energy of the electron should have a fixed value defined by the masses of the three particles involved in the decay. This is not observed as can be seen on the following examples. HEP: Neutrino Physics I 2 Experimental Beta Decay Spectra: From G.J. Neary, Proc. Phys. Soc. (London), A175, 71 (1940). From J.R.

HEP: Neutrino Physics I 3 From these and many more examples it is seen that the electrons from beta decay have a continuum of energies ranging from zero to some maximum value. This discrepancy between theory and experiment was the beta decay crisis. One way out was suggested by Niels Bohr: a possible violation of the conservation of energy in nuclear processes.

  • Explaining LSND by a Decaying Sterile Neutrino Sergio Palomares-Ruiz Silvia Pascoli Thomas Schwetz Abstract: Appearance Based on Neutrinoin Decay
    Published by Institute of Physics Publishing for SISSA Received: May 31, 2005 Revised: August 22, 2005 Accepted: September 8, 2005 Published: September 19, 2005 Explaining LSND by a decaying sterile neutrino Sergio Palomares-Ruiz Department of Physics and Astronomy, Vanderbilt University JHEP09(2005)048 Nashville, TN 37235, U.S.A. E-mail: [email protected] Silvia Pascoli Physics Department, Theory Division, CERN CH–1211 Geneva 23, Switzerland E-mail: [email protected] Thomas Schwetz Scuola Internazionale Superiore di Studi Avanzati Via Beirut 2–4, I–34014 Trieste, Italy E-mail: [email protected] Abstract: We propose an explanation of the LSND evidence for electron antineutrino appearance based on neutrino decay. We introduce a heavy neutrino, which is produced in pion and muon decays because of a small mixing with muon neutrinos, and then decays into a scalar particle and a light neutrino, predominantly of the electron type. We require values of gm few eV, g being the neutrino-scalar coupling and m the heavy neutrino 4 ∼ 4 mass, e.g. m in the range from 1 keV to 1 MeV and g 10−6–10−3. Performing a fit 4 ∼ to the LSND data as well as all relevant null-result experiments, we show that all data can be explained within this decay scenario. In the minimal version of the decay model, we predict a signal in the upcoming MiniBooNE experiment corresponding to a transition probability of the same order as seen in LSND. In addition, we show that extending our model to two nearly degenerate heavy neutrinos it is possible to introduce CP violation in the decay, which can lead to a suppression of the signal in MiniBooNE running in the neutrino mode.
