How Macroscopic Limits on Neutron Star Baryon Loss Yield Microscopic Limits on Non-Standard-Model Baryon Decay
Jeffrey M. Berryman, Susan Gardner, Mohammadreza Zakeri
We investigate how our baryon-loss limits from anomalous binary-pulsar period lengthening can be interpreted microscopically to yield specific constraints on the particle physics o…
Neutrino Self-Interactions: A White Paper
Jeffrey M. Berryman, Nikita Blinov, Vedran Brdar +31
Neutrinos are the Standard Model (SM) particles which we understand the least, often due to how weakly they interact with the other SM particles. Beyond this, very little is known…
Neutron Stars with Baryon Number Violation, Probing Dark Sectors
Jeffrey M. Berryman, Susan Gardner, Mohammadreza Zakeri
The neutron lifetime anomaly has been used to motivate the introduction of new physics with hidden-sector particles coupled to baryon number, and on which neutron stars provide pow…
Statistical significance of the sterile-neutrino hypothesis in the context of reactor and gallium data
Jeffrey M. Berryman, Pilar Coloma, Patrick Huber +2
We evaluate the statistical significance of the 3+1 sterile-neutrino hypothesis using and disappearance data from reactor, solar and gallium radioactive source expe…
Neutron star structure with a new force between quarks
Jeffrey M. Berryman, Susan Gardner
The discovery of nondiffuse sources of gravitational waves through compact-object mergers opens new prospects for the study of physics beyond the Standard Model. In this paper, we…
Future searches for light sterile neutrinos at nuclear reactors
Jeffrey M. Berryman, Luis A. Delgadillo, Patrick Huber
We study the optimization of a green-field, two-baseline reactor experiment with respect to the sensitivity for electron antineutrino disappearance in search of a light sterile neu…
Sterile Neutrinos and the Global Reactor Antineutrino Dataset
Jeffrey M. Berryman, Patrick Huber
We present results from global fits to the available reactor antineutrino dataset, as of Fall 2019, to determine the global preference for a fourth, sterile neutrino. We have separ…
Searches for Decays of New Particles in the DUNE Multi-Purpose Near Detector
Jeffrey M. Berryman, André de Gouvêa, Patrick J. Fox +3
One proposed component of the upcoming Deep Underground Neutrino Experiment (DUNE) near detector complex is a multi-purpose, magnetized, gaseous argon time projection chamber: the…
Reevaluating Reactor Antineutrino Anomalies with Updated Flux Predictions
Jeffrey Berryman, Patrick Huber
Hints for the existence of a sterile neutrino at nuclear reactors are reexamined using two updated predictions for the fluxes of antineutrinos produced in fissions. These new predi…
Constraining Sterile Neutrino Cosmology with Terrestrial Oscillation Experiments
Jeffrey M. Berryman
We explore the complementarity between terrestrial neutrino oscillation experiments and astrophysical/cosmological measurements in probing the existence of sterile neutrinos. We fi…
Shining Light on the Mass Scale and Nature of Neutrinos with
Jeffrey M. Berryman, André de Gouvêa, Kevin J. Kelly +1
The discovery of neutrino oscillations invites many fundamental physics questions that have yet to be answered. Two of these questions are simple, easy to state, and essential: Wha…
Particle physics origin of the 5 MeV bump in the reactor antineutrino spectrum?
Jeffrey M. Berryman, Vedran Brdar, Patrick Huber
One of the most puzzling questions in neutrino physics is the origin of the excess at 5 MeV in the reactor antineutrino spectrum. In this paper, we explore the excess via the react…
Lepton-Number-Charged Scalars and Neutrino Beamstrahlung
Jeffrey M. Berryman, André de Gouvêa, Kevin J. Kelly +1
Experimentally, baryon number minus lepton number, , appears to be a good global symmetry of nature. We explore the consequences of the existence of gauge-singlet scalar field…
Dark Matter and Neutrino Mass from the Smallest Non-Abelian Chiral Dark Sector
Jeffrey M. Berryman, André de Gouvêa, Kevin J. Kelly +1
All pieces of concrete evidence for phenomena outside the standard model (SM) - neutrino masses and dark matter - are consistent with the existence of new degrees of freedom that i…
Standard model flavor from an symmetry
Jeffrey M. Berryman, Daniel Hernández
We propose that the flavor structure of the standard model is based on a horizontal symmetry. It generically predicts (i) a parametrically small mass for the lightest charg…
On Lepton-Number-Violating Searches for Muon to Positron Conversion
Jeffrey M. Berryman, André de Gouvêa, Kevin J. Kelly +1
There is no guarantee that the violation of lepton number, assuming it exists, will primarily manifest itself in neutrinoless double beta decay (). Lepton-number violation an…
Imperfect Mirrors of the Standard Model
Jeffrey M. Berryman, André de Gouvêa, Daniel Hernández +1
Inspired by the Standard Model of particle physics, we discuss a mechanism for constructing chiral, anomaly-free gauge theories. The gauge symmetries and particle content of such t…
Large, Extra Dimensions at the Deep Underground Neutrino Experiment
Jeffrey M. Berryman, André de Gouvêa, Kevin J. Kelly +2
We investigate the potential of the long-baseline Deep Underground Neutrino Experiment (DUNE) to study large-extra-dimension (LED) models originally proposed to explain the smallne…
A Sterile Neutrino at DUNE
Jeffrey M. Berryman, Andre de Gouvea, Kevin J. Kelly +1
We investigate the potential for the Deep Underground Neutrino Experiment (DUNE) to probe the existence and effects of a fourth neutrino mass-eigenstate. We study the mixing of the…
Solar Neutrinos and the Decaying Neutrino Hypothesis
Jeffrey M. Berryman, Andre de Gouvea, Daniel Hernandez
We explore, mostly using data from solar neutrino experiments, the hypothesis that the neutrino mass eigenstates are unstable. We find that, by combining B solar neutrino data…
Non-Unitary Neutrino Propagation From Neutrino Decay
Jeffrey M. Berryman, André de Gouvêa, Daniel Hernández +1
Neutrino propagation in space-time is not constrained to be unitary if very light states - lighter than the active neutrinos - exist into which neutrinos may decay. If this is the…
