Forward tracking at the next e+ e- collider part II: Experimental challenges and detector design

Abstract

We present the second in a series of studies into the forward tracking system for a future linear +e? collider with a center-of-mass energy in the range from 250 GeV to 3 TeV. In this note a number of specific challenges are investigated, which have caused a degradation of the tracking and vertexing performance in the forward region in previous experiments. We perform a quantitative analysis of the dependence of the tracking performance on detector design parameters and identify several ways to mitigate the performance loss for charged particles emitted at shallow angle.
