“…Geometry Description Markup Language (GDML) [9] is a popular extensible markup language designed for detector description in high energy physics experiments [10,11,12]. In the following sections, we will introduce how to exchange the geometry information for liquid detector with GDML and tessellated 3D detector modeling [13,14], so that the dynamic geometry information can be shared between computational fluid dynamics (CFD) simulation and particle transportation simulation.…”

The non-uniformity of liquid in a detector is difficult to be described with the traditional detector description method used in Geant4. To solve the simulation and reconstruction problem with dynamic and non-uniform liquid-based detector, a method of combining GDML and tessellated 3D modeling is put forward to export the detector geometry information from computational fluid dynamics simulation software and import it into the detector simulation software. This method can be used to study the effects of non-uniformity on detector performance. It can be further used to solve other dynamic geometry-related problems in particle and nuclear physics experiments.

“…The BESIII detector is a magnetic spectrometer [10] located at the Beijing Electron Positron Collider (BEPCII) [11]. The cylindrical core of the BESIII detector consists of a helium-based multilayer drift chamber (MDC), a plastic scintillator time-of-flight system (TOF), and a CsI (Tl) electromagnetic calorimeter (EMC), which are all enclosed in a superconducting solenoidal magnet providing a 1.0 T magnetic field [12]. The solenoid is supported by an octagonal flux-return yoke with resistive plate counter muon identifier modules interleaved with steel.…”

“…The cylindrical core of the BESIII detector covers 93% of the full solid angle and consists of a helium-based multilayer drift chamber (MDC), a plastic scintillator time-of-flight system (TOF), and a CsI(Tl) electromagnetic calorimeter (EMC), which are all enclosed in a superconducting solenoidal magnet providing a 1.0 T magnetic field. [8] The solenoid is supported by an octagonal flux-return yoke with resistive plate counter muon identification modules interleaved with steel. The charged-particle momentum resolution at 1 GeV/c is 0.5%, and the specific energy loss (dE/dx) resolution is 6% for electrons from Bhabha scattering.…”

By analyzing 2.93 fb −1 of e + e − collision data taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, the branching fractions of the inclusive decays D + → K 0 S X and D 0 → K 0 S X are measured to be (32.78 ± 0.13 ± 0.27)% and (20.54 ± 0.12 ± 0.18)%, respectively, where the first uncertainties are statistical and the second are systematic. These results are consistent with the world averages of previous measurements, but with improved precision.
