“…The CEPC will hosts two interaction points (IP) on the main ring, where the detector at each IP records collision data under different center of mass energies varying from √ s = 91.2 GeV as a Z factory to √ s = 240 GeV as a Higgs factory. To fulfill the physics goals, a baseline concept of the detector is developed based on the International Large Detector (ILD) concept [8] with further optimizations for the CEPC environment. From the most inner sub-detector component, the detector concept is composed of a silicon vertex detector, a silicon inner tracker consisting of micro strip detectors, a Time Projection Chamber (TPC), a silicon external tracker, ultra-fine segmented calorimeters, an Electromagnetic CALorimeter (ECAL) and an Hadronic CALorimeter (HCAL), a 3T superconducting solenoid, and a muon detector [4].…”

The precision of the yield measurement of the Higgs boson decaying into a pair of Z bosons process at the Circular Electron Positron Collider (CEPC) is evaluated. Including the recoil Z boson associated with the Higgs production (Higgsstrahlung) total three Z bosons are involved for this channel, from which final states characterized by the presence of a pair of leptons, quarks, and neutrinos are chosen for the signal. Two analysis approaches are compared and the final precision of σ ZH •BR(H → ZZ * ) is estimated to be 7.9% using a multivariate analysis technique, based on boosted decision trees. The relative precision of the Higgs boson width, using this H → ZZ * decay topology, is estimated by combining the obtained result with the precision of the inclusive ZH cross section measurement.

“…The event samples of e + e − → b b was generated in center of mass energy of 250 GeV by WHIZARD 1.95 [4]. The full Monte Carlo simulation (MC) was done with Mokka based on Geant4 framework with the reference geometry of the International Large Detector (ILD) concept used in the studies of Detailed Baseline Design report [5], ILD v1 o5 model. The model includes silicon pixel and strip detectors, a time projection chamber, precisely segmented electromagnetic and hadron calorimeters (ECAL and HCAL) and a 3.5 Tesla solenoid magnet.…”

The process e + e − → q q plays an important role in electroweak precision measurements. We are studying this process with ILD full simulation. The key for the reconstruction of the quark pair final states is quark charge identification (ID). We report the progress of charge ID study in detail. In particular, we investigate the performance of the charge ID for each decay mode of the heavy hadrons to know the possibilities of improvements of the charge ID.

“…More recently it has been realised that the particle identification (PID) ability to distinguish different kinds of charged hadrons provides important additional information [1,2,3]. Some proposed detector concepts like ILD [4,5] at the ILC [6] or the CEPC [7] detector offer PID via the specific energy loss (dE/dx) in their gaseous main tracking devices, which could be complemented by time-of-flight (TOF) measurements. For the other detector concepts which rely on silicon tracking only, TOF would be the only possibility for charged hadron PID.…”

We present an overview of a study on precise mass reconstruction and identification of charged hadrons (π ± , K ± , p) using time-of-flight measurements in the electromagnetic calorimeter of a typical Higgs factory detector. Time-of-flight measurements can take advantage of fast timing Si sensors with a time resolution in the order of 10 ps. A precise time-of-flight measurement might contribute to the kaon mass determination and can improve particle identification in the momentum regions inaccessible for the dE/dx method. In this contribution, we discuss the current status and the challenges of the time-of-flight approach for a precise reconstruction of charged hadron masses.
