Influence of beam related background on ILD reconstruction
About
At the ILC machine induced backgrounds, mainly electron-positron pairs from beamstrahlung, will be the most important source of unwanted interactions. Methods of generating, simulating and imposing pair-background on physics events are presented and influence of this background on ILD reconstruction is reviewed. Effects of the background on various ILD detectors are shown for nominal beam parameters and for SB09 reduced beam parameter set and an example of a physics analysis performed with overlayed pair background is given.
