Description

In the TeV-scale collider physics, many important final states include 6 or more jets where jet clustering is essential for the event reconstruction. If many heavy-flavor jets are included in the final states such as Higgs bosons decaying into two b-quarks, the jets can be identified using the vertex information. Our study with ILC detector full-MC simulation has shown a significant improvement in counting b-hadrons with the new algorithm using vertex information. This algorithm shall be especially important to measure Higgs self coupling, which is one of the most important but difficult measurements in ILC.
