2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/39199We present results of simulations of the quenched quarkonium spectrum at two values of the lattice spacing and for quark masses around $m_c$ using the tadpole improved clover action. Attention is focussed on the lowest lying S and P states, and the triplet fine structure is obtained for the first time using a relativistic action.12 pages, 17 figuresHigh Energy Physics - Latticetext
