Abstract

Abstract We investigate the tracker configuration optimization for the Circular Electron Position Collider (CEPC), a proposed Higgs and Z factory. Fixing the construction cost comparable to that of the baseline detector design and considering the benchmark channels (Zff̅WW fusion with Hff̅, ZHννff̅, and  tt̅bb̅μνμud) of various operating modes of the CEPC, we obtain the optimal tracker radius that provides the best average resolution of the track momentum or jet energy. The optimal tracker radii for track momentum resolution range from 1.59 m to 1.73 m and for jet energy resolution from 1.82 m to 1.97 m, depending on the benchmark channels. Compared to the jets, the tracks prefer a smaller radius and a longer length because the track momentum resolution degrades more significantly than jet energy resolution in the forward region. The benchmark channel for Z-pole prefers a smaller radius and longer length compared to other benchmark channels because the final state particles at the Z-pole have a more forward distribution. We also analyze the scaling behavior of the optimal tracker configuration at floating construction cost and observe a weak dependence.
