Scalar-Magnetometer Search for Ultralight Dark Photon Dark Matter with a Single-Site, Two-Sensor Array: A 6-Channel DTFT Likelihood Analysis with Scalar Optically Pumped Magnetometers
Peisen Zhao, Ole Behrens, Maja Benning +6
We report on a laboratory search for ultralight dark photon dark matter using a single-site, two-sensor scalar magnetometer array. The experiment employs two scalar optically pumpe…
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 Exotic Interactions between Antimatter
Lei Cong, Filip Ficek, Pavel Fadeev +2
We show that atomic antimatter spectroscopy can be used to search for new bosons that carry spin-dependent exotic forces between antifermions. A comparison of a recent precise meas…
Momentum and Matter Matter for Axion Dark Matter Matters on Earth
Abhishek Banerjee, Itay M. Bloch, Quentin Bonnefoy +5
We investigate the implications of matter effects to searches for axion Dark Matter on Earth. The finite momentum of axion Dark Matter is crucial to elucidating the effects of Eart…
Detecting the Coupling of Axion Dark Matter to Neutron Spins at Spallation Sources via Rabi Oscillation
Peter Fierlinger, Jie Sheng, Yevgeny V. Stadnik +1
We propose a novel detection method for axion dark matter using the Rabi oscillation of neutron spins in beam-based measurements. If axions couple to neutron spins, a background os…
Spin-dependent exotic interactions
Lei Cong, Wei Ji, Pavel Fadeev +8
Novel interactions beyond the four known fundamental forces in nature (electromagnetic, gravitational, strong and weak interactions), may arise due to "new physics" beyond the stan…
