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.
