Managing Information for Sparsely Distributed Articles and Readers: The Virtual Journals of the Joint Institute for Nuclear Astrophysics (JINA)

Richard H. Cyburt, Sam M. Austin, Timothy C. Beers +5

The research area of nuclear astrophysics is characterized by a need for information published in tens of journals in several fields and an extremely dilute distribution of researc…

Evaluation of Modern 3He(alpha,gamma)7Be Data

Richard H. Cyburt, Barry Davids

In both the Sun and the early universe, the 3He(alpha,gamma)7Be reaction plays a key role. The rate of this reaction is the least certain nuclear input needed to calculate both the…

A Bitter Pill: The Primordial Lithium Problem Worsens

Richard H. Cyburt, Brian D. Fields, Keith A. Olive

The lithium problem arises from the significant discrepancy between the primordial 7Li abundance as predicted by BBN theory and the WMAP baryon density, and the pre-Galactic lithiu…

Bound-State Effects on Light-Element Abundances in Gravitino Dark Matter Scenarios

Richard H. Cyburt, John Ellis, Brian D. Fields +2

If the gravitino is the lightest supersymmetric particle and the long-lived next-to-lightest sparticle (NSP) is the stau, the charged partner of the tau lepton, it may be metastabl…

Radiative neutron capture on a proton at BBN energies

S. Ando, R. H. Cyburt, S. W. Hong +1

The total cross section for radiative neutron capture on a proton, , is evaluated at big bang nucleosynthesis (BBN) energies. The electromagnetic transition amplitudes…

New BBN limits on Physics Beyond the Standard Model from He4

Richard H. Cyburt, Brian D. Fields, Keith A. Olive +1

A recent analysis of the He4 abundance determined from observations of extragalactic HII regions indicates a significantly greater uncertainty for the He4 mass fraction. The derive…
