摘要:
The inclusive production of the charged vector meson rho(+/-)(770) in hadronic Z decays is measured with the ALEPH detector at the LEP collider. Decays of rho(+/-) --> pi(0) + pi(+/-) are reconstructed for x > 0.05 where x = E-rho/E-beam. The results are compared with Monte Carlo model predictions and OPAL measurements. Bose-Einstein effects are found to be important in extracting rho(+/-)(770) from two pion invariant mass spectra.
