Complementary Probes of Light Higgsinos: Electroweak Precision Measurements and Dark Matter Direct Detection
Koichi Hamaguchi, Natsumi Nagata, Genta Osaki
Although higgsinos are well motivated to be light from the viewpoint of naturalness, they remain difficult to detect experimentally because they interact only through electroweak i…

Electroweak Precision Data as a Gateway to Light Higgsinos
Natsumi Nagata, Genta Osaki
We investigate the prospects of probing weak-scale higgsinos through electroweak precision measurements at a future collider. In the Minimal Supersymmetric Standard Model…

Axion dark matter detection via shift current
Dan Kondo, Takahiro Morimoto, Genta Osaki +1
We propose a novel method to detect axion dark matter based on a topological phenomenon known as the shift current. We make use of the second-order nonlinearity of the shift curren…
