We classify rank zero 5d SCFTs geometrically engineered from M-theory on quasi-
homogeneous compound Du Val isolated threefold singularities. For all such theories,
we characterize the Higgs Branch, by computing the dimension, the continuous and
discrete symmetry groups, as well as more refined details such as the charges of the
hypermultiplets under these groups. We derive these data by means of a gauge-theoretic
method, that we have recently introduced, based on establishing a correspondence
between an adjoint Higgs field and the M-theory geometry. As a byproduct, this further
allows us to construct several T-brane backgrounds, that yield inequivalent 5d spectra
but are associated with the same geometry.
