Existing samples

Estimated reading time: 14 minutes

Three complete samples of Higgs signal (also top pair at 350 GeV) and Standard Model backgrounds are generated for CEPC detector design and optimizaition. These samples are generated at 240 GeV, 250 GeV, and 350 GeV, respectively. All these sample can be found at /cefs/data.

/cefs/data/stdhep

generator samples, whose dir-structure is taken as standard. The others, such as full simulation and reconstructed samples take same directory structure.

/cefs/data/FullSim

Geant4 simulation results containing hits

/cefs/data/RecData

reconstruction samples with hits and reconstructed physics objects

/cefs/data/DstData

slimmed reconstruction samples without hits

The corresponding sub-directories, the center of mass energy and the versions of detector geometry are also used to marked the samples
