Theoretical description of proton-deuteron interactions using exact two-body dynamic of femtoscopic correlation method Open
Modeling proton-deuteron interactions is particularly challenging. Due the deuteron's large size, the interaction can extend over several femtometers. The degree to which it can be modeled as a two-body problem might also be questioned. On…
