Preliminary charged particle multiplicity in $e^+e^- \rightarrow W^+W^-$
The charged particle multiplicity and momentum distribution of fully hadronic and semi-leptonic W+W- decays is measured at the ALEPH experiment from $\sqrt{s}$=189 GeV to 207 GeV. The data is compared with Monte Carlo simulations with and without colour reconnection. The combined data sample of 625...

Sumario: | The charged particle multiplicity and momentum distribution of fully hadronic and semi-leptonic W+W- decays is measured at the ALEPH experiment from $\sqrt{s}$=189 GeV to 207 GeV. The data is compared with Monte Carlo simulations with and without colour reconnection. The combined data sample of 625 pb^-1 at $<\sqrt{s}>$=198 GeV is compatible with the Monte Carlo predictions over most of the momenta spectra. |
