Short-distance production of three particles with large scattering length
Timothy G. Backert, Sebastian Dietz, Hans-Werner Hammer +2
The short-distance production of multi-particle states in high-energy nuclear reactions provides a unique way to study the low-energy properties of few-body systems. In particular,…
Three- and four-boson systems expanded around the unitarity limit: Application to He
Feng Wu, Xincheng Lin, Ubirajara van Kolck +1
The three- and four-boson systems with a large scattering length and a short effective range in the two-body sector are studied in the framework of Short-Range Effective Field Theo…
What is a resonance? And why does it matter?
Sebastian König, Kévin Fossez, Rimantas Lazauskas
The resonance phenomenon is of central importance in many areas of physics, with particular significance in the study of nuclear structure and reactions. Starting from the classica…
The Three-Body Limit Cycle: Universal Form for General Regulators
Langxuan Chen, Feng Wu, Xincheng Lin +3
The Efimov effect, a remarkable realization of discrete scale invariance, emerges in the three-body problem with short-range interactions and is understood as a renormalization gro…
Perturbative EFT calculation of the deuteron longitudinal response function
Andrew J. Andis, Songlin Lyu, Bingwei Long +1
In this work, we study the longitudinal response function of the deuteron up to next-to-next-to-leading order in chiral effective field theory (Chiral EFT). We use an approach that…
Simplification of chiral nuclear forces near the unitarity limit
Songlin Lyu, Lin Zuo, Rui Peng +2
Modern theory approaches for describing atomic nuclei often make use of on an effective theory that constructs the interaction between nucleons systematically based on Quantum Chro…
