Towards a new generation axion helioscope [PDF]

, 2011
We study the feasibility of a new generation axion helioscope, the most ambitious and promising detector of solar axions to date. We show that large improvements in magnetic field volume, x-ray focusing optics and detector backgrounds are possible beyond

Axion-like Particles from String Compactifications [PDF]

, 2013
We review how axion-like particles (ALPs) naturally emerge in the low-energy effective field theory of string compactifications. We focus on the study of their mass spectrum and couplings, stressing that they depend on the mechanism used to fix the ...

Axions and their Relatives [PDF]

, 2006
A review of the status of axions and axion-like particles is given. Special attention is devoted to the recent results of the PVLAS collaboration, which are in conflict with the CAST data and with the astrophysical constraints.

Electroweak ALP searches at a muon collider

Journal of High Energy Physics, 2022
A high-energy muon collider with center-of-mass energy around and above 10 TeV is also a vector boson fusion (VBF) machine, due to the significant virtual electroweak (EW) gauge boson content of high-energy muon beams.

Axions - Motivation, limits and searches [PDF]

, 2006
The axion solution of the strong CP problem provides a number of possible windows to physics beyond the standard model, notably in the form of searches for solar axions and for galactic axion dark matter, but in a broader context also inspires searches ...

Constraining axion and ALP dark matter from misalignment during reheating

Physical Review D, 2023
We explore the phenomenology of QCD axion and axion-like particle (ALP) dark matter production via misalignment during inflationary reheating. We investigate scenarios involving inflaton oscillating in a generic potential $\sim ϕ^n$, considering inflaton decay and annihilation for reheating.

Probing axion-like particles coupling to gluons at the LHC

Journal of High Energy Physics, 2022
Assuming ALPs couple to gluons only, they can be produced via the pp → aj process and decay into two jets at the LHC. When the coupling parameter, C G ~ $$ {C}_{\overset{\sim }{G}} $$ /f a , is small, the lifetime of ALPs can be long enough leading to ...

Signatures of photon and axion-like particle mixing in the gamma-ray burst jet [PDF]

, 2011
Photons couple to Axion-Like Particles (ALPs) or more generally to any pseudo Nambu-Goldstone boson in the presence of an external electromagnetic field.

Lepton-flavor violating axions at MEG II

Journal of High Energy Physics, 2022
We study the sensitivity of the existing MEG data to lepton flavor violating axion-like particles produced through μ + → e + aγ and estimate the discovery potential for the upcoming MEG II experiment in this channel.
