Sensitivity to Axion-like Particles with a Three-Beam Stimulated Resonant Photon Collider around the eV Mass Range

Abstract

We propose a three-beam stimulated resonant photon collider with focused laser fields in order to directly produce an axion-like particle (ALP) with the two beams and to stimulate its decay by the remaining one. The expected sensitivity around the eV mass range has been evaluated. The result shows that the sensitivity can reach the ALP-photon coupling down to O(10−14) GeV−1 with 1 J class short-pulsed lasers.

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

“…Thus, ALP mass scanning is possible even though central values, θ c , are varied in a discrete step if the E cms uncertainty defined by laser pulse duration and the focal parameters is consistent with the discrete angle step in θ c in a search. For more information, see [20].…”

“…NAω, NA2ω, LA2ω and LA3ω are sensitivities corresponding to the individual arrows classified in Figure 10. The details of the numerical calculations and the derivation of the upper limits on the coupling can be found in [20,21], respectively. The red shaded area shows the excluded range based on SRPC in quasiparallel collision geometry (SAPPHIRES01) [19].…”

“…In our previous study of a quasi-parallel collision system, we focused two lasers into the same optical axis and collided them at a shallow incident angle to search for ALPs in the sub-eV mass range [15][16][17][18][19]. Recently, we have proposed and demonstrated a pilot search for heavier ALPs based on a three-beam stimulated resonant collider ( t SRPC) [20,21]. In the near future, we plan to search for ALPs by continuously changing collision angles in the eV mass range.…”

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. [68], a photon collider of the resonance of the stimulation with the fields of the focused lasers is investigated. The present collider with three beams is used for the direct production of particles like axions.…”
