title = "A precision measurement of neutron β-decay angular correlations with pulsed cold neutrons - The abBA experiment",
abstract = "The abBA collaboration is developing a new type of field-expansion spectrometer to measure neutron beta decay angular parameters, a, b, B, and A, to the 0.1% precision level. This precision will be achieved by combining three new technical approaches; a pulsed cold neutron beam, a 3He neutron spin filter, and segmented large-area thin-dead layer silicon detectors. Both the electron and proton resulting from the decay will be guided by electric and magnetic fields and detected in coincidence by two 2π solid-angle silicon detectors. For the neutron polarization-dependent observables A and B, a novel precision neutron polarimetry technique has been developed. The parameters a and b will be obtained from the proton time-of-flight and the measured electron energy spectrum. Measurement of the four parameters in the same apparatus provides a redundant determination of parameter λ=gA/g V, providing a test of the standard electroweak interaction.",
