Search for the Neutron Decay n -> X plus gamma Where X is a Dark Matter Particle

PHYSICAL REVIEW LETTERS, 121(2).

By: Z. Tang *, M. Blatnik *, L. Broussard *, J. Choi n, S. Clayton *, C. Cude-Woods n, S. Currie *, D. Fellers * ...

TL;DR: A search for a previously unobserved dark matter decay mode over the allowed range of energies of the monoenergetic γ ray for X to be dark matter finds nothing and excludes the possibility of a sufficiently strong branch to explain the lifetime discrepancy with 97% confidence.
