1. A minimal SU(5) SuperGUT in pure gravity mediation / Evans, Jason L. ; Nagata, Natsumi ; Olive, Keith A.
The lack of evidence for low-scale supersymmetry suggests that the scale of supersymmetry breaking may be higher than originally anticipated. [...]

2. Minimal gauged U(1)LαLβ models driven into a corner / Asai, Kento ; Hamaguchi, Koichi ; Nagata, Natsumi ; Tseng, Shih-Yen ; et al
It is well known that the differences between the lepton numbers can be gauged with the standard model matter content. [...]

3. Singlet Dirac fermion dark matter with mediators at loop / Hisano, Junji ; Nagai, Ryo ; Nagata, Natsumi
We study the phenomenology of singlet Dirac fermion dark matter in the simplified models where the dark matter interacts with the Standard Model particles at loop-level with the help of either colored or non-colored mediators. [...]

4. Limit on the axion decay constant from the cooling neutron star in Cassiopeia A / Hamaguchi, Koichi ; Nagata, Natsumi ; Yanagi, Keisuke ; Zheng, Jiaming
The observed rapid cooling of the neutron star (NS) located at the center of the supernova remnant Cassiopeia A (Cas A) can be explained in the minimal NS cooling scenario. [...]

5. Non-universal gaugino masses in the NMSSM / Kawamura, Junichiro ; Kobayashi, Tatsuo ; Nagata, Natsumi
The Next-to-Minimal Supersymmetric Standard Model (NMSSM) provides a natural framework to realize a low-scale supersymmetric (SUSY) model, where a singlet superfield is added to the minimal model to generate a SUSY-scale higgsino mass term with its vacuum expectation value. [...]

We analyze a displaced dilepton signal expected at the LHC for a tau left sneutrino as the lightest supersymmetric particle with a mass in the range 45–100 GeV. [...]

10. Predictions for the neutrino parameters in the minimal gauged U(1)Lμ-Lτ model / Asai, Kento ; Hamaguchi, Koichi ; Nagata, Natsumi
We study the structure of the neutrino-mass matrix in the minimal gauged U(1)Lμ-Lτ model, where three right-handed neutrinos are added to the Standard Model in order to obtain non-zero masses for the active neutrinos. [...]
