Title: New result for the neutron $β$ -asymmetry parameter $A_{0}$ from UCNA

Abstract

Background: The neutron β-decay asymmetry parameter A₀ defines the angular correlation between the spin of the neutron and the momentum of the emitted electron. Values for A₀ permit an extraction of the ratio of the weak axial-vector to vector coupling constants, λ≡g_A/g_V, which under assumption of the conserved vector current hypothesis (g_V=1) determines g_A. Precise values for g_A are important as a benchmark for lattice QCD calculations and as a test of the standard model. Purpose: The UCNA experiment, carried out at the Ultracold Neutron (UCN) source at the Los Alamos Neutron Science Center, was the first measurement of any neutron β-decay angular correlation performed with UCN. This article reports the most precise result for A₀ obtained to date from the UCNA experiment, as a result of higher statistics and reduced key systematic uncertainties, including from the neutron polarization and the characterization of the electron detector response. Methods: UCN produced via the downscattering of moderated spallation neutrons in a solid deuterium crystal were polarized via transport through a 7 T polarizing magnet and a spin flipper, which permitted selection of either spin state. The UCN were then contained within a 3-m long cylindrical decay volume, situated along the central axismore »« less

Values for A0 permit an extraction of the ratio of the weak axial-vector to vector coupling constants, λ≡gA/gV, which under assumption of the conserved vector current hypothesis (gV=1) determines gA. Precise values for gA are important as a benchmark for lattice QCD calculations and as a test of the standard model. Purpose: The UCNA experiment, carried out at the Ultracold Neutron (UCN) source at the Los Alamos Neutron Science Center, was the first measurement of any neutron β-decay angular correlation performed with UCN. This article reports the most precise result for A0 obtained to date from the UCNA experiment, as a result of higher statistics and reduced key systematic uncertainties, including from the neutron polarization and the characterization of the electron detector response. Methods: UCN produced via the downscattering of moderated spallation neutrons in a solid deuterium crystal were polarized via transport through a 7 T polarizing magnet and a spin flipper, which permitted selection of either spin state. The UCN were then contained within a 3-m long cylindrical decay volume, situated along the central axis of a superconducting 1 T solenoidal spectrometer. With the neutron spins then oriented parallel or anti-parallel to the solenoidal field, an asymmetry in the numbers of emitted decay electrons detected in two electron detector packages located on both ends of the spectrometer permitted an extraction of A0. Results: The UCNA experiment reports a new 0.67% precision result for A0 of A0= -0.12054(44)stat(68)syst, which yields λ=gA/gV= -1.2783(22). Combination with the previous UCNA result and accounting for correlated systematic uncertainties produces A0= -0.12015(34)stat(63)syst and λ=gA/gV= -1.2772(20).Conclusions: This new result for A0 and gA/gV from the UCNA experiment has provided confirmation of the shift in values for gA/gV that has emerged in the published results from more recent experiments, which are in striking disagreement with the results from older experiments. Individual systematic corrections to the asymmetries in older experiments (published prior to 2002) were >10%, whereas those in the more recent ones (published after 2002) have been of the scale of <2%. Finally, the impact of these older results on the global average will be minimized should future measurements of A0 reach the 0.1% level of precision with central values near the most recent results.},

Precision Measurement Of The Neutron's Beta Asymmetry Using Ultra-Cold Neutrons

Journal Article Makela, M ; Back, H O ; Melconian, D ; ... - AIP Conference Proceedings

A measurement of A{beta}, the correlation between the electron momentum and neutron (n) spin (the beta asymmetry) in n beta-decay, together with the n lifetime, provides a method for extracting fundamental parameters for the charged-current weak interaction of the nucleon. In particular when combined with decay measurements, one can extract the Vud element of the CKM matrix, a critical element in CKM unitarity tests. By using a new SD2 super-thermal source at LANSCE, large fluxes of UCN (ultra-cold neutrons) are expected for the UCNA project. These UCN will be 100% polarized using a 7 T magnetic field, and directed intomore »« less

A high-field adiabatic fast passage ultracold neutron spin flipper for the UCNA experiment

Journal Article Holley, A. T. ; Pattie, R. W. ; Young, A. R. ; ... - Review of Scientific Instruments

The UCNA collaboration is making a precision measurement of the {beta} asymmetry (A) in free neutron decay using polarized ultracold neutrons (UCN). A critical component of this experiment is an adiabatic fast passage neutron spin flipper capable of efficient operation in ambient magnetic fields on the order of 1 T. The requirement that it operate in a high field necessitated the construction of a free neutron spin flipper based, for the first time, on a birdcage resonator. The design, construction, and initial testing of this spin flipper prior to its use in the first measurement of A with UCN duringmore »« less

$Λ_{c} \to N$ form factors from lattice QCD and phenomenology of $Λ_{c} \to n ℓ^{+} ν_{ℓ}$ and $Λ_{c} \to p μ^{+} μ^{-}$ decays

Journal Article Meinel, Stefan - Physical Review D

We report on a lattice QCD determination of the Λ_c→N vector, axial vector, and tensor form factors. Here, the calculation was performed with 2+1 flavors of domain wall fermions at lattice spacings of a≈0.11 and 0.085 fm and pion masses in the range 230 MeV≲ m_π ≲ 350 MeV. The form factors are extrapolated to the continuum limit and the physical pion mass using modified z expansions. The rates of the charged-current decays Λ_c→ne+ν_e and Λ_c→nμ+ν_μ are predicted to be (0.405 ± 0.016_stat ± 0.020_syst)|V_cd|²ps^₋1 and (0.396 ± 0.016_stat ± 0.020_syst)|V_cd|²ps^₋1, respectively.

Improved limits on Fierz interference using asymmetry measurements from the Ultracold Neutron Asymmetry (UCNA) experiment

Journal Article Sun, X. ; Adamek, E. ; Allgeier, B. ; ... - Physical Review C

The Ultracold Neutron Asymmetry (UCNA) experiment was designed to measure the β-decay asymmetry parameter, A₀, for free neutron decay. In the experiment, polarized ultracold neutrons are transported into a decay trap, and their β-decay electrons are detected with ≈4π acceptance into two detector packages which provide position and energy reconstruction. The experiment also has sensitivity to b_n, the Fierz interference term in the neutron β-decay rate. In this work, we determine bn from the energy dependence of A₀ using the data taken during the UCNA 2011–2013 run. In addition, we present the same type of analysis using the earlier 2010more »« less
