      abstract     = {We perform ultrahigh-resolution angle-resolved
                      photoemission experiments at a temperature T=0.8 K on the
                      type-II Weyl semimetal candidate WTe2. We find a surface
                      Fermi arc connecting the bulk electron and hole pockets on
                      the (001) surface. Our results show that the surface Fermi
                      arc connectivity to the bulk bands is strongly mediated by
                      distinct surface resonances dispersing near the border of
                      the surface-projected bulk band gap. By comparing the
                      experimental results to first-principles calculations, we
                      argue that the coupling to these surface resonances, which
                      are topologically trivial, is compatible with the
                      classification of WTe2 as a type-II Weyl semimetal hosting
                      topological Fermi arcs. We further support our conclusion by
                      a systematic characterization of the bulk and surface
                      character of the different bands and discuss the similarity
                      of our findings to the case of topological insulators.},
