Galactic magnetic fields seeded by ultralight dark photons
Joshua Berger, Amit Bhoonah, Joseph Bramante +3
In this work, we show that ultralight dark photons, which couple to the Standard Model photon through kinetic mixing, can potentially source galactic scale magnetic fields. Althoug…

Cosmological Histories in Neutrino Portal Dark Matter
Amro E. B. Abdelrahim, Brian Batell, Joshua Berger +2
We explore the diverse cosmological histories of a dark sector that is connected to the Standard Model (SM) via a Dirac sterile neutrino. The dark sector consists of a complex scal…

Search for a Hidden Sector Scalar from Kaon Decay in the Di-Muon Final State at ICARUS
ICARUS Collaboration, F. Abd Alrahman, P. Abratenko +191
We present a search for long-lived particles (LLPs) produced from kaon decay that decay to two muons inside the ICARUS neutrino detector. This channel would be a signal of hidden s…
