  We present a description of the break-up of halo nuclei in peripheral nuclear
reactions by coupling a model of the projectile motivated by Halo Effective
Field Theory with a fully dynamical treatment of the reaction using the
Dynamical Eikonal Approximation. Our description of the halo system reproduces
its long-range properties, i.e., binding energy and asymptotic normalization
coefficients of bound states and phase shifts of continuum states. As an
application we consider the break-up of 11Be in collisions on Pb and C targets.
Taking the input for our Halo-EFT-inspired description of 11Be from a recent ab
initio calculation of that system yields a good description of the
Coulomb-dominated breakup on Pb at energies up to about 2 MeV, with the result
essentially independent of the short-distance part of the halo wave function.
However, the nuclear dominated break-up on C is more sensitive to short-range
physics. The role of spectroscopic factors and possible extensions of our
approach to include additional short-range mechanisms are also discussed.
