Fundamental Neutron Physics: a White Paper on Progress and Prospects in the US
R. Alarcon, A. Aleksandrova, S. Baeßler +88
Fundamental neutron physics, combining precision measurements and theory, probes particle physics at short range with reach well beyond the highest energies probed by the LHC. Sign…
The Two-Photon Exchange Experiment at DESY
R. Alarcon, R. Beck, J. C. Bernauer +36
We propose a new measurement of the ratio of positron-proton to electron-proton elastic scattering at DESY. The purpose is to determine the contributions beyond single-photon excha…
Searching for New Physics with DarkLight at the ARIEL Electron-Linac
The DarkLight Collaboration, E. Cline, R. Corliss +43
The search for a dark photon holds considerable interest in the physics community. Such a force carrier would begin to illuminate the dark sector. Many experiments have searched fo…
Measurement of the Parity-Odd Angular Distribution of Gamma Rays From Polarized Neutron Capture on Cl
N. Fomin, R. Alarcon, L. Alonzi +61
We report a measurement of two energy-weighted gamma cascade angular distributions from polarized slow neutron capture on the Cl nucleus, one parity-odd correlation propor…
Measurement of the Charge-Averaged Elastic Lepton-Proton Scattering Cross Section by the OLYMPUS Experiment
J. C. Bernauer, A. Schmidt, B. S. Henderson +67
We report the first measurement of the average of the electron-proton and positron-proton elastic scattering cross sections. This lepton charge-averaged cross section is insensitiv…
The neutron electric dipole moment experiment at the Spallation Neutron Source
K. K. H. Leung, M. Ahmed, R. Alarcon +90
Novel experimental techniques are required to make the next big leap in neutron electric dipole moment experimental sensitivity, both in terms of statistics and systematic error co…
The Nab Experiment: A Precision Measurement of Unpolarized Neutron Beta Decay
J. Fry, R. Alarcon, S. Baessler +69
Neutron beta decay is one of the most fundamental processes in nuclear physics and provides sensitive means to uncover the details of the weak interaction. Neutron beta decay can e…
First Observation of -odd Asymmetry in Polarized Neutron Capture on Hydrogen
D. Blyth, J. Fry, N. Fomin +61
We report the first observation of the parity-violating 2.2 MeV gamma-ray asymmetry in neutron-proton capture using polarized cold neutrons incident on a liquid parahydr…
New measurement of the scattering cross section of slow neutrons on liquid parahydrogen from neutron transmission
K. B. Grammer, R. Alarcon, L. Barrón-Palos +25
Liquid hydrogen is a dense Bose fluid whose equilibrium properties are both calculable from first principles using various theoretical approaches and of interest for the understand…
Neutron Beta Decay Studies with Nab
S. Baeßler, R. Alarcon, L. P. Alonzi +31
Precision measurements in neutron beta decay serve to determine the coupling constants of beta decay and allow for several stringent tests of the standard model. This paper discuss…
Nab: Measurement Principles, Apparatus and Uncertainties
D. Pocanic, R. Alarcon, L. P. Alonzi +23
The Nab collaboration will perform a precise measurement of 'a', the electron-neutrino correlation parameter, and 'b', the Fierz interference term in neutron beta decay, in the Fun…
