Abstract
Influence of Vertex Detector (VTX) geometry on jet flavour tagging performance was studied in presence of e+e- pair background from beamstrahlung in the International Linear Collider (ILC). Five layer "long-barrel" VTX geometry with varying layer thickness, space resolution and radius of the first layer was tested with fast simulation tools. Influence of VTX geometry and e+e- pair background on measurement of SM and MSSM Higgs boson branching ratios was also studied.
