Probing Sub-MeV Dark Matter with Neutron-Capture Spectroscopy
B. Meirose, D. Milstead
We present a general, discovery-grade framework for searching for weakly coupled new particles emitted in nuclear de-excitation following neutron capture. Rather than relying on is…
Avoiding Blindness in Baryon Number Violating Processes: Free-Beam and Intranuclear Paths to Neutron-Antineutron Transitions
Joshua L. Barrow, Peter Fierlinger, Yuri Kamyshkov +4
Experimental searches for neutron--antineutron () transitions can be considered via two approaches: conversion in free-neutron beams and intranuclear transfor…
Advancements in Computing and Simulation Techniques for the HIBEAM-NNBAR Experiment
Bernhard Meirose, Jorge Amaral, Alexander Burgman +14
The HIBEAM-NNBAR program is a proposed two-stage experiment at the European Spallation Source focusing on searches for baryon number violation processes as well as ultralight dark…
Fundamental Nuclear and Particle Physics At Neutron Sources
H. Abele, J. Amaral, W. R. Anthony +121
Fundamental neutron and neutrino physics at neutron sources, combining precision measurements and theory, can probe new physics at energy scales well beyond the highest energies pr…
Searching for Long-Lived Particles in Free Neutron Experiments
B. Meirose, R. Nieuwenhuis, R. Pasechnik +3
We explore the decay of free neutrons into exotic long-lived particles, whose decays could be detected in the next-generation free neutron experiments. We show that such a possibil…
