Exploring pseudo-Nambu-Goldstone bosons in the sub-eV to 10 keV mass range with stimulated photon collider

Kensuke Homma


Generic laboratory searches for pseudo-Nambu-Goldstone bosons (pNGBs)

in weak-coupling domains beyond the GUT scale are

indispensable for understanding the dark components in the universe.

We introduce a novel approach to search for resonantly produced pNGBs

coupled to two photons in the mass range from sub-eV to 10~keV

by colliding plural laser fields to induce the rare scattering process.
