Exploring pseudo-Nambu--Goldstone bosons by stimulated photon colliders in the mass range 0.1~eV to 10~keV
Kensuke Homma, Yuichi Toyota
Searching for pseudo-Nambu--Goldstone bosons (pNGBs) in weak-coupling domains is crucial for understanding the dark components in the universe. We propose searching for pNGBs coupl…
Probing vacuum birefringence under a high-intensity laser field with gamma-ray polarimetry at the GeV scale
Yoshihide Nakamiya, Kensuke Homma
Probing vacuum structures deformed by high intense fields is of great interest in general. In the context of quantum electrodynamics (QED), the vacuum exposed by a linearly polariz…
Search for sub-eV scalar and pseudoscalar resonances via four-wave mixing with a laser collider
Takashi Hasebe, Kensuke Homma, Yoshihide Nakamiya +5
The quasi-parallel photon-photon scattering by combining two-color laser fields is an approach to produce resonant states of low-mass fields in laboratory. In this system resonance…
Testing helicity dependent scattering in the region of MeV
Kensuke Homma, Kayo Matsuura, Kazuhisa Nakajima
Light-by-light scatterings contain rich information on the photon coupling to virtual and real particle states. In the context of quantum electrodynamics (QED), photons can couple…
