Ratio of Baryon to Meson and Baryon Antibaryon Correlation in e+e－ Annihilation under Two Kinds of Color Connections

  •  School of Physics and Microelectronics,Shandong University,Ji'nan 250100,China

  • The ratio of final baryon to meson and baryon antibaryon correlation in e+e－ annihilation are considered as sensitive observables to test the hadronizition models,because among the results obtainted in different popular hadronizition models,only those from JETSET event generator can fit experimental data by adjusting extra ad hoc parameters. We replace the color neutral flow connection,which is the results in large Nc limit and is used in JETSET,with the color separate connection,which is allowed by PQCD,and calculate these observables. We compare the obtained results with those from the standard JETSET7.4 code and the available experimental data. We find that the results and the relevant properties are consistent with data. This shows that the consistency of the data with the results from the standard JETSET7.4 code for these properties does not mean that the traditional color neutral flow is the only color connection selected by NPQCD. The 100% color separate connection is also possible.

Abstract: The ratio of final baryon to meson and baryon antibaryon correlation in e+e－ annihilation are considered as sensitive observables to test the hadronizition models,because among the results obtainted in different popular hadronizition models,only those from JETSET event generator can fit experimental data by adjusting extra ad hoc parameters. We replace the color neutral flow connection,which is the results in large Nc limit and is used in JETSET,with the color separate connection,which is allowed by PQCD,and calculate these observables. We compare the obtained results with those from the standard JETSET7.4 code and the available experimental data. We find that the results and the relevant properties are consistent with data. This shows that the consistency of the data with the results from the standard JETSET7.4 code for these properties does not mean that the traditional color neutral flow is the only color connection selected by NPQCD. The 100% color separate connection is also possible.
