The two rare processes share common parameters through the C and E functions. One can do a parametric study by evaluating both process numerically as a function of model parameters (assumed free).
Supersymmetric particles with natural mass differences (O(10-3)) can boost the rare D -> mm decay rate by 6-7 orders of magnitude
Supersymmetric particles with natural mass differences (O(10-3)) can boost the D mixing rate by 6-7 orders of magnitude
High rate hadroproduction of D0’s at hadron colliders and precision vertex measurement of D0 decays are both necessary, a challenging task.
The next generation charm experiment at BES III can search D0 CCNC decay rates of order 10-10, probing squark mass up to TeV scale
