In order to see the effects of the choice of the cut, we have studied Higgs production in and .Figs.3.4-a) to -c) plot reconstructed Higgs mass distributions with three different values of cut: 1.0-, 1.5-, and 2.0-.These three figures should be compared to each other as well as to Fig.3.4-d) which is the mass distribution with smeared generated tracks. We can see that when n is too small, we have a upward tail in the distribution because of undeleted clusters due to charged hadrons. On the other hand, a too large n misdeletes clusters due to neutral hadrons and consequently lowers the center value of the mass peak.
