Measurement of the $\tau$ topological branching ratios

Mostrar otras versiones (2)

Using data collected in the DELPHI detector at LEP-1, measurements of the inclusive tau branching ratios for decay modes containing one, three, or five charged particles have been performed: B/sub 1/ identical to B( tau /sup -/ to (particle)/sup $/ ->or=0 pi /sup 0/>or =0K/sup 0/ nu /sub tau /...
