2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/45039A new supersymmetry is proposed for hadrons containing a single heavy quark. This supersymmetry is based on a new approximation to those hadrons, which we would consider as a further step beyond the spectator light diquark model of baryons. The heavy diquark effective theory is constructed by the techniques introduced in a different context by Georgi and Wise$^1$ and by Carone$^2$. This theory can be incorporated into a supersymmetric theory together with Heavy Quark Effective Theory, and leads to a common universal Isgur-Wise function for mesons and baryons./.12 pages, Syracuse University preprint SU-4240-561High Energy Physics - Phenomenologytext
