Open system approach to neutrinos propagating in an ultralight scalar background
Lua F. T. Airoldi, Gustavo F. S. Alves, Pedro A. N. Machado +1
We examine decoherence in neutrino oscillations induced by an ultralight scalar field coupled to neutrinos. The scalar induces time- and position-dependent shifts in the neutrino m…

Mass Reconstruction of Heavy Neutral Leptons from Stopped Mesons
Gustavo F. S. Alves, P. S. Bhupal Dev, Kevin J. Kelly +1
Heavy neutral leptons (HNLs), depending on their mass and mixing, can be efficiently produced in meson decays from the target or absorber in short- to medium-baseline accelerator n…

Towards a Robust Exclusion of the Sterile-Neutrino Explanation of Short-Baseline Anomalies
Ohana Benevides Rodrigues, Matheus Hostert, Kevin J. Kelly +4
The sterile neutrino interpretation of the LSND and MiniBooNE neutrino anomalies is currently being tested at three Liquid Argon detectors: MicroBooNE, SBND, and ICARUS. It has bee…
