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…
