Momentum-space probability density of ${}^6$He in Halo Effective Field Theory

Understand

We compute the momentum-space probability density of ${}^6$He at leading order in Halo EFT.

• In this framework, the ${}^6$He nucleus is treated as a three-body problem with a ${}^4$He core ($c$) and two valence neutrons ($n$).
• This requires the $nn$ and $nc$ t-matrices as well as a $cnn$ force as input in the Faddeev equations.
• Since the $nc$ t-matrix corresponds to an energy-dependent potential, we consider the consequent modifications to the standard normalization and orthogonality conditions.
