Query: Neutron transfer reactions in halo effective field theory   Direct reaction experiments provide a powerful tool to probe the structure of
neutron-rich nuclei like beryllium-11. We use halo effective field theory to
calculate the cross section of the deuteron-induced neutron transfer reaction
${}^{10}\text{Be}(\text{d},\,\text{p}){}^{11}\text{Be}$. The effective theory
contains dynamical fields for the beryllium-10 core, the neutron, and the
proton. In contrast, the deuteron and the beryllium-11 halo nucleus are
generated dynamically from contact interactions using experimental and ab
initio input. The reaction amplitude is constructed up to next-to-leading order
in an expansion in the ratio of the length scales characterizing the core and
the halo. The Coulomb repulsion between core and proton is treated
perturbatively. Finally, we compare our results to cross-section data and other
calculations.
