Constraints on a possible dineutron state from pionless EFT
H. W. Hammer, Sebastian König
We investigate the sensitivity of the three-nucleon system to changes in the neutron-neutron scattering length to next-to-leading order in the pionless effective field theory, focu…
Constraining Low-Energy Proton Capture on Beryllium-7 through Charge Radius Measurements
Emil Ryberg, Christian Forssén, H. -W. Hammer +1
In this paper, we point out that a measurement of the charge radius of Boron-8 provides indirect access to the S-factor for radiative proton capture on Beryllium-7 at low energies.…
The proton-deuteron system in pionless EFT revisited
Sebastian König, Harald W. Grießhammer, H. -W. Hammer
We provide a detailed discussion of the low-energy proton-deuteron system in pionless effective field theory, considering both the spin-quartet and doublet S-wave channels. Extendi…
