Özet
We present the numerical investigation of the fermionic two-body decays of squarks in the minimal supersymmetric standard model with complex parameters. In the analysis, we particularly take into account the cosmological bounds imposed by Wilkinson Microwave Anisotropy Probe data. We find that the phase dependences of the decay widths of the third family squarks, as well as those of the first and second families, are quite significant which can provide viable probes of additional CP sources. We plot the CP-phase dependences for each fermionic two-body decay channel of squarks (q)overtilde(i) (i = 1, 2, q = u, d, c, s, t, b) and speculate about the branching ratios and total (two-body) decay widths.
