Design and Construction of a Variable-Angle Three-Beam Stimulated Resonant Photon Collider toward eV-Scale ALP Search

Abstract

We aim to search for axion-like particles in the eV mass range using a variable-angle stimulated resonance photon collider (SRPC) with three intense laser beams. By changing angle of incidence of the three beams, the center-of-mass-system collision energy can be varied and the eV mass range can be continuously searched for. In this paper, we present the design and construction of such a variable-angle three-beam SRPC (tSRPC), the verification of the variable-angle mechanism using a calibration laser, and realistic sensitivity projections for searches in the near future.

Origins and Natures of Inflation, Dark Matter and Dark Energy

“…Secondly, both theoretical and experimental studies of dark matter are described. In particular, quark-nugget dark matter [65][66][67] and axion-like particles [68][69][70] are investigated. After that, the subjects of dark energy [71,72] and modified gravity theories [73] are explored.…”

“…In Ref. [70], the plan and composition of a photon collider are presented. The photon collider that provides the resonance for the stimulation has three very strong laser beams with variable angles.…”
