Constraints and Sensitivities for Dipole-Portal Heavy Neutral Leptons from ND280 and its Upgrade
Ming-Shau Liu, Nicholas Kamp, Carlos A. Argüelles
We report new constraints and sensitivities to heavy neutral leptons (HNLs) with transition magnetic moments, also known as dipole-portal HNLs. This is accomplished using data from…
The Neutrino Slice at Muon Colliders
Luc Bojorquez-Lopez, Matheus Hostert, Carlos A. Argüelles +1
Muon colliders provide an exciting new direction to expand the energy frontier of particle physics. We point out a new use of these facilities for neutrino and beyond the Standard…
Probing the connection between IceCube neutrinos and MOJAVE AGN
R. Abbasi, M. Ackermann, J. Adams +420
Active Galactic Nuclei (AGN) are prime candidate sources of the high-energy, astrophysical neutrinos detected by IceCube. This is demonstrated by the real-time multi-messenger dete…
Search for a light sterile neutrino with 7.5 years of IceCube DeepCore data
R. Abbasi, M. Ackermann, J. Adams +420
We present a search for an eV-scale sterile neutrino using 7.5 years of data from the IceCube DeepCore detector. The analysis uses a sample of 21,914 events with energies between 5…
Search for neutrino emission from hard X-ray AGN with IceCube
R. Abbasi, M. Ackermann, J. Adams +422
Active Galactic Nuclei (AGN) are promising candidate sources of high-energy astrophysical neutrinos since they provide environments rich in matter and photon targets where cosmic r…
IceCube Search for Neutrino Emission from X-ray Bright Seyfert Galaxies
R. Abbasi, M. Ackermann, J. Adams +421
The recent IceCube detection of TeV neutrino emission from the nearby active galaxy NGC 1068 suggests that active galactic nuclei (AGN) could make a sizable contribution to the dif…
Exploration of mass splitting and muon/tau mixing parameters for an eV-scale sterile neutrino with IceCube
R. Abbasi, M. Ackermann, J. Adams +421
We present the first three-parameter fit to a 3+1 sterile neutrino model using 7.634 years of data from the IceCube Neutrino Observatory on charged-current inter…
Resonant Neutrino Flavor Conversion in the Atmosphere
Connor Sponsler, Matheus Hostert, Ivan Martinez-Soler +1
Neutrinos produced in the atmosphere traverse a column density of air before being detected at neutrino observatories like IceCube or KM3NeT. In this work, we extend the neutrino f…
Ultra-light Dark Matter Limits from Astrophysical Neutrino Flavor
Carlos A. Argüelles, Kareem Farrag, Teppei Katori
Ultra-light dark matter is a class of dark matter models where the mass of the dark matter particle is very small and the dark matter behaves as a classical field pervading our gal…
From the Dawn of Neutrino Astronomy to A New View of the Extreme Universe
C. A. Argüelles, F. Halzen, N. Kurahashi
Over the past decade, neutrino astronomy has emerged as a new window into the extreme and hidden universe. Current-generation experiments have detected high-energy neutrinos of ast…
Methods and stability tests associated with the sterile neutrino search using improved high-energy event reconstruction in IceCube
IceCube Collaboration, R. Abbasi, M. Ackermann +419
We provide supporting details for the search for a 3+1 sterile neutrino using data collected over eleven years at the IceCube Neutrino Observatory. The analysis uses atmospheric mu…
