Abstract

Among Z0 decay modes, it’s decay into charm mesons has been measured with relatively large rate. In this article, Z0 decay into D0, \(\bar {D}^{0}\), D±, D∗(2010)± mesons via fragmentation is studied. To this purpose, at first we will calculate the fragmentation functions of c quark into the pseudoscalar and vector states of D mesons in the lowset order of pQCD. Then using these functions we will calculate branching ratios, \(\frac {{\Gamma }_{Z^{0}\rightarrow (D^{i} +X)}}{{\Gamma }_{tot}}\) for the decay of Z0 into the D and D∗ mesons, considering longitudinal and transverse polarizations. Note that our results have a good agreement with the exprimental data and shows the dominant mechanism in direct fragmentation quarks into D and D* are c and \(\bar {c}\) quarks fragmentation.
