Boosted Tau Lepton as a Microscope and Macroscope

Figure 4

Geant4 simulation for a 50 TeV tau penetrating interleaved detectors made by 3 layer RPC (in blue), lead tungstate (PbWO4, in green), and copper (in red), each with 20 cm’s length. The energetic tau flies like a muon and then decays into 3 charged pions and neutrinos. The gamma rays shows in green, electrons in red, and electron neutrinos in white.
