Measurement of the inclusive production of the d*0 (2007) meson in hadronic z decays with the aleph detector at the lep collider

A measurement of the inclusive production rate of the charmed D*0 (2007) meson in hadronic Z decays is performed using data from the ALEPH detector at the LEP collider. A total of 3,239,746 hadronic events are selected from data recorded by ALEPH from the 1991 to 1995 running periods. Decays of D*0 D0pi0 are reconstructed for x_E >= 0.3 where x_E = E_D*0 / Ebeam. The average D*0 multiplicity per hadronic event is evaluated to be: =0.289 +- 0.031 +- 0.067 +- 0.009 where the first error is statistical and the second is systematic. The third error is from the extrapolation to x_E = 0. The rates and differential cross-sections are compared with Monte Carlo model predictions. The signal significance is improved explicitly by applying machine learning algorithms based on Multi Variate classification methods of artificial intelligence applications.
