Fine-tunings in radiative -particle capture on C at astrophysical energies
Ulf-G. MeiÃner, 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…

Fine-tunings in nucleosynthesis and the emergence of life: Status and perspectives
Ulf-G. MeiÃner, 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…

A study of the fine-structure constant dependence of radiative capture in Halo-EFT
Ulf-G. MeiÃner, Bernard Ch. Metsch, Helen Meyer
We study the fine-structure constant dependence of the rates of some selected radiative capture reactions within the framework of so-called Halo Effective Field Theory in order to…
