We explore the dynamics of hard-core lattice bosons in the presence of strong
non-local particle loss. The evolution occurs on two distinct time-scales,
first a rapid strongly correlated decay into a highly degenerate Zeno state
subspace, followed by a slow almost coherent evolution. We analytically solve
the fast initial dynamics of the system, where we specifically focus on an
initial Mott insulator state, and perform an analysis of the particle
arrangements in the Zeno subspace. We investigate the secondary slow relaxation
process that follows and find an intricate regime where the competition between
dissipation and coherence results in various types of interacting particle
complexes. We classify them and analyse their spectral properties in the
presence and absence of nearest-neighbor interactions. Under certain
circumstances the dispersion relations of the complexes feature flat bands,
which are a result of an effective spin-orbit coupling.
