Identifying the Origin of Longevity of Metastable Stau at the LHC
Takumi Ito, Kouhei Nakaji, Satoshi Shirai
In the framework of the supersymmetric standard model, the lighter stau often becomes long-lived. Such longevity of the stau is realized in three well-motivated scenarios: (A) the…
LHC signature with long-lived stau in high reheating temperature scenario
Motoi Endo, Koichi Hamaguchi, Kouhei Nakaji
We study the possibility of observing the stau signal at LHC in case that the gravitino is the lightest supersymmetric particle and the stau is the next lightest supersymmetric par…
Probing High Reheating Temperature Scenarios at the LHC with Long-Lived Staus
Motoi Endo, Koichi Hamaguchi, Kouhei Nakaji
We investigate the possibility of probing high reheating temperature scenarios at the LHC, in supersymmetric models where the gravitino is the lightest supersymmetric particle, and…
Inverse Problem of Cosmic-Ray Electron/Positron from Dark Matter
Koichi Hamaguchi, Kouhei Nakaji, Eita Nakamura
We discuss the possibility of solving the inverse problem of the cosmic-ray electron/positron from decaying/annihilating dark matter, and show simple analytic formulae to reconstru…
