Big bang nucleosynthesis (BBN) describes the production of the lightest nuclides via a
dynamic interplay among the four fundamental forces during the first seconds of cosmic time …

The status of tests of the standard electroweak model and of searches for new physics in
allowed nuclear β decay and neutron decay is reviewed including both theoretical and …

We present cosmological parameter results from the final full-mission Planck measurements
of the cosmic microwave background (CMB) anisotropies, combining information from the …

This paper presents cosmological results based on full-mission Planck observations of
temperature and polarization anisotropies of the cosmic microwave background (CMB) …

We present cosmological parameter results from the final full-mission Planck measurements
of the CMB anisotropies. We find good consistency with the standard spatially-flat 6 …

We assess the status of big-bang nucleosynthesis (BBN) in light of the final Planck data
release and other recent developments, and in anticipation of future measurements. Planck …

We report an improved measurement of the free neutron lifetime τ n using the UCN τ
apparatus at the Los Alamos Neutron Science Center. We count a total of approximately 38× …

We present the current accounting of systematic effect uncertainties for the Low Frequency
Instrument (LFI) that are relevant to the 2015 release of the Planck cosmological results …

We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

There is a long-standing discrepancy between the neutron lifetime measured in beam and
bottle experiments. We propose to explain this anomaly by a dark decay channel for the …
