Constraints on Neutrino Self-Interactions from IceCube Observation of NGC 1068
Jeffrey M. Hyde
The active galaxy NGC 1068 was recently identified by the IceCube neutrino observatory as the first known steady-state, extragalactic neutrino point source, associated with about 7…
High-Energy Astrophysical Neutrinos from Cosmic Strings
Cyril Creque-Sarbinowski, Jeffrey Hyde, Marc Kamionkowski
Cosmic strings that couple to neutrinos may account for a portion of the high-energy astrophysical neutrino (HEAN) flux seen by IceCube. Here, we calculate the observed spectrum of…
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…
Using Secondary Tau Neutrinos to Probe Heavy Dark Matter Decays in Earth
Matthew Saveliev, Jeffrey Hyde
Dark matter particles can be gravitationally trapped by celestial bodies, motivating searches for localized annihilation or decay. If neutrinos are among the decay products, then I…
Resonant Neutrino Self-Interactions
Cyril Creque-Sarbinowski, Jeffrey Hyde, Marc Kamionkowski
If neutrinos have self-interactions, these will induce scatterings between astrophysical and cosmic neutrinos. Prior work proposed to look for possible resulting resonance features…
Exploring Hubble Constant Data in an Introductory Course
Jeffrey M. Hyde
Popular accounts of exciting discoveries often draw students to physics and astronomy, but at the introductory level it is challenging to connect with these in a meaningful way. Th…
Detecting CP Violation in the Presence of Non-Standard Neutrino Interactions
Jeffrey M. Hyde
New physics beyond the Standard Model could appear at long baseline oscillation experiments as non-standard interactions (NSI) between neutrinos and matter. If so, determination of…
Biprobability approach to CP phase degeneracy from non-standard neutrino interactions
Jeffrey M. Hyde
Non-standard interactions (NSI) between neutrinos and matter at long-baseline experiments could make determination of the CP-violating phase ambiguous due to interference…
Sensitivity of gravitational waves from preheating to a scalar field's interactions
Jeffrey M. Hyde
After inflation, a period of preheating may have produced a stochastic background of high frequency gravitational waves (GWs) that would persist until today. The nature of the infl…
Cosmic Strings in Hidden Sectors: 1. Radiation of Standard Model Particles
Andrew J. Long, Jeffrey M. Hyde, Tanmay Vachaspati
In hidden sector models with an extra U(1) gauge group, new fields can interact with the Standard Model only through gauge kinetic mixing and the Higgs portal. After the U(1) is sp…
Dark Strings and their Couplings to the Standard Model
Jeffrey M. Hyde, Andrew J. Long, Tanmay Vachaspati
We consider the Standard Model extended by a hidden sector U(1)_X symmetry that is spontaneously broken at the TeV scale by the vacuum expectation value of an additional scalar fie…
