摘要：

Six-jet events via WW pairs, e(+)e(-) --> W+W- --> q(1) (q(1)) over bar q(2) (q(2)) over bar gg are studied at tree level using helicity amplitudes. This is the dominant production mechanism for six-jet final states at LEP II energy. ISR effects are taken into account. Total production rates as a function of y(cut) are given. The relevance of these processes for the issue of colour reconnection is discussed. The cross section for five-jet production via WW pairs at LEP II is also presented.
