Ab initio calculation of the spectrum and structure of O

Evgeny Epelbaum, Hermann Krebs, Timo A. Lähde +3

We present ab initio lattice calculations of the low-energy even-parity states of O using chiral nuclear effective field theory. We find good agreement with the empirical en…

Lattice effective field theory for nuclei from A = 4 to A = 28

Timo A. Lähde, Evgeny Epelbaum, Hermann Krebs +3

We present an overview of the extension of Nuclear Lattice Effective Field Theory simulations to the regime of medium-mass nuclei. We focus on the determination of the ground-state…

Lattice Effective Field Theory for Medium-Mass Nuclei

Timo A. Lähde, Evgeny Epelbaum, Hermann Krebs +3

We extend Nuclear Lattice Effective Field Theory (NLEFT) to medium-mass nuclei, and present results for the ground states of alpha nuclei from He to Si, calculated up to…

Limits on Tensor Coupling from Neutron -Decay

Robert W. Pattie, Kevin P. Hickerson, Albert R. Young

Limits on the tensor couplings generating a Fierz interference term, b, in mixed Gamow-Teller Fermi decays can be derived by combining data from measurements of angular correlation…

Adiabatic projection method for scattering and reactions on the lattice

Michelle Pine, Dean Lee, Gautam Rupak

We demonstrate and test the adiabatic projection method, a general new framework for calculating scattering and reactions on the lattice. The method is based upon calculating a low…

Sensitivity studies for r-process nucleosynthesis in three astrophysical scenarios

R. Surman, M. Mumpower, J. Cass +3

In rapid neutron capture, or r-process, nucleosynthesis, heavy elements are built up via a sequence of neutron captures and beta decays that involves thousands of nuclei far from s…

Neutron capture rates and r-process nucleosynthesis

R. Surman, M. Mumpower, G. C. McLaughlin +3

Simulations of r-process nucleosynthesis require nuclear physics information for thousands of neutron-rich nuclear species from the line of stability to the neutron drip line. Whil…

Finite volume effects in low-energy neutron-deuteron scattering

Alexander Rokash, Evgeny Epelbaum, Hermann Krebs +2

We present a lattice calculation of neutron-deuteron scattering at very low energies and investigate in detail the impact of the topological finite-volume corrections. Our calculat…

Dependence of the triple-alpha process on the fundamental constants of nature

Evgeny Epelbaum, Hermann Krebs, Timo A. Lähde +2

We present an ab initio calculation of the quark mass dependence of the ground state energies of ^4He, ^8Be and ^{12}C, and of the energy of the Hoyle state in ^{12}C. These invest…
