DSiD: a Delphes Detector for ILC Physics Studies

Abstract

We describe DSiD, a fast simulation Delphes detector for the International Linear Collider (ILC) based on the full simulation performance of the SiD detector. SiD is one of two detectors described in the ILC Technical Design Report (TDR). The tracking efficiency, tracking momentum resolution, electromagnetic and hadronic calorimeter energy resolution, particle identification and flavor tagging efficiencies are taken from the Detailed Baseline Design (DBD) study as described in ILC TDR Volume 4: Detectors. In a cross-check study with $4\times 10^6$ $e^{+}{e}^{-}\to b\bar{b}$ events generated at $\sqrt{s}=500$ GeV and simulated by Delphes with the DSiD detector card, these performance characteristics are measured and found to be commensurate with the DBD results. For a new physics use case example, we describe a study of Next-to-Minimal Supersymmetric $e^{+}{e}^{-}\to 2{\chi }_3\to 2{\chi }_{1}2h_1$ with $h_1\to 2a_1$ or $h_1\to b\bar{b}$ at the $\sqrt{s}=500$ GeV ILC. The card is available on HepForge.
