2.7 Further Experimental Considerations

In studies of the Higgs particles at JLC, accurate tracking and event kinematic reconstructions are essential. One needs to investigate the performances of such key techniques under very realistic experimental environments. The extremely high luminosity of order of 10³⁴ cm^-2s^-1, which is about 2 order higher than that at LEP, and the beam structure necessary for the acceleration in the linear collider JLC, make the experimental situation more severe than that at LEP and SLC in the following points;

• Large number of noise hits on the vertex detectors due to huge number of e⁺ e^- pairs created by beam-beam interactions [21]. It makes proper associations of the hits for the tracking difficult especially for the low momentum tracks, which are rather important for ${\rm b}$
