Extension of Schwinger's Partial Symmetry (PS) Principle at the phenomenological level is suggested for the simulation of e.m. interaction of new quark flavors (charm, upsilon) as well as of diquarks (qD) which are particularly useful for the description of baryonium (BB) states. For this purpose we invoke an important aspect of the principle, viz., equal strengths (&gem;') of the magnetic and charge (timesm,)interactions of V-meson fields with q-quarks (u, d, s), where the observable V-meson masses (m, == m, , m, , rns) effectively play the role of the (invisible) quark masses, and the VMD principle of e.m. substitution determines the magnetic interaction in terms of the universal charge interaction. For e.m. interactions of charm (c) and upsilon (Q), the natural V-field choices are the $-ion (m, = rn$) and &meson (m, = rno N 9.4) with e.m. substitutions $, + f[2(2)"a]/ 3) eg&'A, and 8, + 21j2 eaeg$A, (ec = j or -f). This facilitates an unambiguous set of predictions of the magnetic and transition moments of all the charmed hadrons, in conjunction with Schwinger's (p, w, 4) model for coupling to q-quarks. The feasibility of early experimental tests of this model, mainly via transition moments, is discussed. The general feature in every case is an inverse proportionality of the magnetic interaction of each quark component to the appropriate V-meson mass. In a similar spirit, with the assumption of "elementarity" of diquarks (qD) under reasonable kinematical conditions, the e.m. interaction of diquarks is postulated through the intermediary of a baryonium V-meson (I = 0 or I), with typical mass m = 1.94. This gives good agreement for gA!g%, (= -1.22) and P~,I'~ (= -1.45), even for a 56-like nucleon.
