QCD Axion Search with ILC Beam Facility
Hajime Fukuda, Hidetoshi Otono, Satoshi Shirai
One of the most promising methods to search for axions is a light-shining-through-walls (LSW) experiment. In this work, we discuss the possibility of performing an LSW experiment a…
Witten effect, anomaly inflow, and charge teleportation
Hajime Fukuda, Kazuya Yonekura
We study a phenomenon that electric charges are "teleported" between two spatially separated objects without exchanging charged particles at all. For example, this phenomenon happe…
Axion strings are superconducting
Hajime Fukuda, Aneesh V. Manohar, Hitoshi Murayama +1
We explore the cosmological consequences of the superconductivity of QCD axion strings. Axion strings can support a sizeable chiral electric current and charge, which alters their…
Aspects of Nonlinear Effect on Black Hole Superradiance
Hajime Fukuda, Kazunori Nakayama
Under some conditions, light boson fields grow exponentially around a rotating black hole, called the superradiance instability. We discuss effects of nonlinear interactions of the…
Cornering Higgsino: Use of Soft Displaced Track
Hajime Fukuda, Natsumi Nagata, Hideyuki Oide +2
Higgsino has been intensively searched for in the LHC experiments in recent years. Currently, there is an uncharted region beyond the LEP Higgsino mass limit where the mass splitti…
How Heavy can Neutralino Dark Matter be?
Hajime Fukuda, Feng Luo, Satoshi Shirai
What is the upper limit of the mass of the neutralino dark matter whose thermal relic is consistent with the observation? If the neutralino dark matter and colored sparticles are e…
