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. 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…
Exploration of the LHCb states and possible resonances in a unitary coupled-channel model
Chao-Wei Shen, Deborah Rönchen, Ulf-G. Meißner +2
We extend our previous study of the interactions of within an analytic, unitary, coupled-channel approach by including the chann…
