Solar opacity calculations using the super-transition-array method
M. Krief, A. Feigel, D. Gazit
A new opacity model based on the Super-Transition-Array (STA) method for the calculation of monochromatic opacities of local thermodynamic equilibrium plasmas, was developed. The a…
Effects of three-nucleon forces and two-body currents on Gamow-Teller strengths
A. Ekström, G. R. Jansen, K. A. Wendt +5
We optimize chiral interactions at next-to-next-to leading order to observables in two- and three-nucleon systems, and compute Gamow-Teller transitions in carbon-14, oxygen-22 and…
Neutrino Breakup of A=3 Nuclei in Supernovae
E. O'Connor, D. Gazit, C. J. Horowitz +2
We extend the virial equation of state to include 3H and 3He nuclei, and predict significant mass-three fractions near the neutrinosphere in supernovae. While alpha particles are o…
Spin-dependent WIMP scattering off nuclei
J. Menendez, D. Gazit, A. Schwenk
Chiral effective field theory (EFT) provides a systematic expansion for the coupling of WIMPs to nucleons at the momentum transfers relevant to direct cold dark matter detection. W…
Solar fusion cross sections II: the pp chain and CNO cycles
E. G. Adelberger, A. B. Balantekin, D. Bemmerer +45
We summarize and critically evaluate the available data on nuclear fusion cross sections important to energy generation in the Sun and other hydrogen-burning stars and to solar neu…
Chiral two-body currents in nuclei: Gamow-Teller transitions and neutrinoless double-beta decay
J. Menéndez, D. Gazit, A. Schwenk
We show that chiral effective field theory (EFT) two-body currents provide important contributions to the quenching of low-momentum-transfer Gamow-Teller transitions, and use chira…
The Coulomb interaction in Helium-3: Interplay of strong short-range and weak long-range potentials
J. Kirscher, D. Gazit
Quantum chromodynamics and the electroweak theory at low energies are prominent instances of the combination of a short-range and a long-range interaction. For the description of l…
Large-scale nuclear structure calculations for spin-dependent WIMP scattering with chiral effective field theory currents
P. Klos, J. Menéndez, D. Gazit +1
We perform state-of-the-art large-scale shell-model calculations of the structure factors for elastic spin-dependent WIMP scattering off 129,131Xe, 127I, 73Ge, 19F, 23Na, 27Al, and…
Effective Field Theory for Lattice Nuclei
N. Barnea, L. Contessi, D. Gazit +2
We show how nuclear effective field theory (EFT) and ab initio nuclear-structure methods can turn input from lattice quantum chromodynamics (LQCD) into predictions for the properti…
Line broadening and the solar opacity problem
M. Krief, A. Feigel, D. Gazit
The calculation of line widths constitutes theoretical and computational challenges in the calculation of opacities of hot dense plasmas. Opacity models use line broadening approxi…
alpha-particle photoabsorption with a realistic nuclear force
D. Gazit, S. Bacca, N. Barnea +2
The 4He total photoabsorption cross section is calculated with the realistic nucleon-nucleon potential Argonne V18 and the three-nucleon force (3NF) Urbana IX. Final state interact…
Solar fusion III: New data and theory for hydrogen-burning stars
B. Acharya, M. Aliotta, A. B. Balantekin +47
In stars that lie on the main sequence in the Hertzsprung-Russel diagram, like our sun, hydrogen is fused to helium in a number of nuclear reaction chains and series, such as the p…
