Elastic deuteron-deuteron scattering in the channel 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 f…
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…
A study of the fine-structure constant dependence of radiative capture in Halo-EFT
Ulf-G. Meißner, 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…
Improved Constraints on the Variation of the Weak Scale from Big Bang Nucleosynthesis
Helen Meyer, Ulf-G. Meißner
We present an improved calculation of the light element abundances in the framework of Big Bang nucleosynthesis as a function of the Higgs vacuum expectation value . We compare…
The electromagnetic fine-structure constant in primordial nucleosynthesis revisited
Ulf-G. Meißner, Bernard Ch. Metsch, Helen Meyer
We study the dependence of the primordial nuclear abundances as a function of the electromagnetic fine-structure constant , keeping all other fundamental constants fixed. We upd…
