Prospects of fast timing detectors for particle identification at future Higgs factories — •Bohdan Dudar1,2, Rémi Ete1, and Jenny List1 — 1DESY, Hamburg, Germany — 2Hamburg University, Germany
Future e+e− colliders are excellent tools to probe fundamental physics beyond Standard Model via Higgs and electroweak precision measurements.
Modern silicon detectors are able to measure time-of-arrival with high precision of O(10 ps). This can be used to measure the time-of-flight (TOF) of the particles and improve their identification.
We develop reconstruction and calibration algorithms based on TOF information to separate π±, K±, p, p particles at future Higgs factory detectors. Furthermore, we study how to implement fast timing silicon layers in the tracking and/or calorimeter systems, in order to derive requirements on the time resolution. As an example case, the ILD detector concept is studied.
The K± mass measurement is a simple benchmark to test the performance of TOF algorithm. A precision at the level of 10 keV can be expected, which would significantly improve the knowledge of the K± mass.
