“…It is possible to keep neutron to photon fake rate below 10 −3 by utilizing modern detector technology. For a one year of data taking period (∼ 10 7 s) and the choice of detector technology, the number of background event is expected to be restricted to less than 1 [5]. Hence this search is considered effectively background free.…”

“…With an additional forward detector, the LUXE experiment can probe a wellmotivated uninvestigated parameter space of a new spin-0 particle (scalar or pseudo-scalar) which couples to photons. This is indicated as LUXE-NPOD: New Physics at Optical Dump [5]. In this proceeding, it will be shown that this setup can probe scalar and pseudo-scalar particle masses up to O(350) MeV and decay constants of O(10 5 − 10 6 ) GeV −1 .…”

The proposed Laser Und XFEL (LUXE) Experiment at DESY, Hamburg, aims to probe QED in the strong field non-perturbative regime. This regime will be created in collisions between high-intensity laser pulses and high-energy electron or photon beams coming from the Eu.XFEL setup. This experiment comes with a unique opportunity to probe physics beyond the standard model. In this proceeding, it is described that with the help of the large photon flux generated at LUXE, axion-like-particles can be probed up to a mass of 350 MeV and with a photon coupling of 3 × 10 −6 GeV −1 . This reach in parameter space is comparable to the projected reach of future experiments like FASER2 in the HL-LHC and NA62 in the dump mode.

LUXE: A new experiment to study non-perturbative QED in electron-laser and photon-laser collisions

The LUXE (Laser Und XFEL Experiment) is a new experiment in planning at DESY Hamburg using the electron beam of the European XFEL. LUXE is intended to study collisions between a high-intensity optical laser and 16.5 GeV electrons from the XFEL electron beam, as well as collisions between the optical laser and high-energy secondary photons. The physics objective of LUXE are processes of quantum electrodynamics (QED) at the strong-field frontier, where the electromagnetic field of the laser is above the Schwinger limit. In this regime, QED is non-perturbative. This manifests itself in the creation of physical electron-positron pairs from the QED vacuum, similar to Hawking radiation from black holes. LUXE intends to measure the positron production rate in an unprecedented laser intensity regime. An overview of the LUXE experimental setup and its challenges will be given, followed by a discussion of the expected physics reach in the context of testing QED in the non-perturbative regime.

Axion-like particles (ALPs) interacting with the Standard Model can be abundantly produced in proton beam fixed-target experiments. Looking for their displaced decays is therefore an effective search strategy for ALPs with a mass in the MeV to GeV range. Focusing on the benchmark models where the ALP interacts dominantly with photons or gluons, we show that the proposed DarkQuest experiment at Fermilab will be able to test parameter space which has been previously inaccessible. We pay particular attention to the self-consistency of gluon-coupled ALP production and decay calculations, which has been recently shown to be a problem in many existing predictions. We also apply these results to explore existing constraints in the ALP parameter space.
