 The study uses the density matrix renormalization group and Chebyshev polynomial expansion technique to investigate the two-hole excitation spectrum of the one-dimensional Hubbard model in the entire filling range from completely occupied band down to half-filling. Multiplan physics is observed, with relevant final states characterized by two to more holes forming stable compound objects or resonances with finite lifetime. The complex multiplan phenomenology is analyzed through local and k-resolve two-hole, three-hole, and four-hole spectra, as well as effective low-energy models. A filter operator technique is presented to extract specific information on final states at a given excitation energy. Dublin's and quadruplein's are well-defined resonances, while multiplans composed of an odd number of holes do not form stable compounds or well-defined resonances unless a nearest neighbor density interaction is added. The Dublin lifetime is strongly k-dependent and infinite at the brillouin's own edges due to hidden charge SU-2 symmetry, which is explicitly broken off half-filling and gives rise to a massive collective excitation even for arbitrary high-dimensional but bipartite lattices.
