✦ Synopsis

We present an attempt to separate between Hisgs boson events (e'e--+ ZH+ q&b) and other physics processes in the 4jet channel (e'e-+ 2'~ w" W, ZZ+ 4je?$, using tbe discriminant analysis and neural networks methods. Events were produced at LEP2 energies, using the LundMonte Carlo generator and the Al@ package. The most discriminant variables as the reconstructed jet mass, tbe jet properties (b-tug, rapidity weighted moments) and other variables are used.
