Elastic deuteron-deuteron scattering within Nuclear Lattice Effective Field Theory

Helen Meyer, Serdar Elhatisari, Fabian Hildenbrand +1

We calculate low-energy deuteron-deuteron scattering in the spin-quintet channel using nuclear lattice effective field theory. The calculation combines chiral interaction…

Fine-tunings in radiative -particle capture on C at astrophysical energies

Ulf-G. Meißner, Bernard Ch. Metsch, Helen Meyer

We investigate the fine-tuning of radiative alpha-particle capture on carbon, , at astrophysical energies. Utilizing results from cluster effective…

Lattice calculation of the Sn isotopes near the proton dripline

Fabian Hildenbrand, Serdar Elhatisari, Ulf-G. Meißner +4

We present the first lattice calculations of the proton-rich tin isotopes Sn to Sn using nuclear lattice effective field theory with high-fideli…

Fine-tunings in nucleosynthesis and the emergence of life: Status and perspectives

Ulf-G. Meißner, Bernard Ch. Metsch, Helen Meyer

We discuss the fine-tunings of nuclear reactions in the Big Bang and in stars and draw some conclusions on the emergence of the light elements and the life-relevant elements carbon…

Bounds on variations of the strange quark mass from Big Bang nucleosynthesis

Ulf-G. Meißner, Bernard Metsch, Helen Meyer

We analyze the effect of a variation of the strange nucleon matrix element on the abundances of the light elements produced in the Big Bang. For…
