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

Journal Article Brown, M. A. -P. ; Dees, E. B. ; Adamek, E. ; ... - Physical Review C

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 anymore »« less

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

Search for the reaction $e^{+} e^{-} \to χ_{c J} π^{+} π^{-}$ and a charmoniumlike structure decaying to $χ_{c J} π^{\pm}$ between 4.18 and 4.60 GeV

Journal Article Ablikim, M. ; Achasov, M. N. ; Adlarson, P. ; ... - Physical Review D

We search for the process e⁺e^– → χ_cJπ⁺π^– (J = 0, 1, 2) and for a charged charmoniumlike state in the χ_cJπ^± subsystem. The search uses datasets collected with the BESIII detector at the BEPCII storage ring at center-of-mass energies between 4.18 GeV and 4.60 GeV. No significant χ_cJπ⁺π^– signals are observed at any center-of-mass energy, and thus upper limits are provided which also serve as limits for a possible charmoniumlike structure in the invariant χ_cJπ^± mass.

First direct constraints on Fierz interference in free-neutron $β$ decay

Journal Article Hickerson, K. P. ; Sun, X. ; Bagdasarova, Y. ; ... - Physical Review C

Precision measurements of free-neutron β decay have been used to precisely constrain our understanding of the weak interaction. However, the neutron Fierz interference term b_n, which is particularly sensitive to beyond-standard-model tensor currents at the TeV scale, has thus far eluded measurement. Here we report the first direct constraints on this term, finding b_n=0.067±0.005_statmore »« less
