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…
Nature of the states from compositeness criteria
Yu-Fei Wang, Chao-Wei Shen, Deborah Rönchen +3
Based on a coupled-channel approach, we investigate the structures of four states through compositeness criteria. Toward a more precise description of the states, we have obt…
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…
Bounds on variations of the strange quark mass from Big Bang nucleosynthesis
Ulf-G. MeiÃner, 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…
meson from lattice QCD
Haobo Yan, Maxim Mai, Marco Garofalo +4
Many excited states in the hadron spectrum have large branching ratios to three-hadron final states. Understanding such particles from first principles QCD requires input from latt…
