Abstract: (SISSA)

The Tibet AS𝛾 experiment, observing cosmic rays/gamma rays above a few TeV, is located at 4,300 m above sea level, in Tibet, China. The experiment is composed of a 65,700 m2 surface airshower array and 3,400 m2 underground water Cherenkov muon detectors. The surface air showerarray is used for reconstructing the primary particle energy and direction, while the undergroundmuon detectors are used for discriminating gamma-ray induced muon-poor air showers from cosmic-ray (proton, helium,...) induced muon-rich air showers. Furthermore, the undergroundmuon detectors turn out to be effective to select the proton component in cosmic rays. We presentthe recent progress on analysis method for the proton energy spectrum in the hundred TeV regionby means of proton selection by the underground muon detector information, and on the recent 100 TeV gamma-ray observation. In addition, we discuss the modelling of the cosmic-ray anisotropy observed in the TeV region.
