In this paper, we explore the phenomenology of massive axionlike particles (ALPs) coupled
to quarks and gluons, dubbed “QCD ALPs,” with an emphasis on the associated low-energy …

What is the highest energy at which gravitons can be observed? We address this question
by studying graviton-to-photon conversion—the inverse-Gertsenshtein effect—in the …

The axion, as a leading dark matter candidate, is the target of many ongoing and proposed
experimental searches based on its coupling to photons. Ultralight axions that couple to …

The newly observed gamma ray burst GRB221009A exhibits the existence of 10 TeV-scale
photons, and the axion-photon conversion has been suggested as a candidate to explain …

High-frequency gravitational waves (f≳ 1 MHz) may provide a unique signature for the
existence of exotic physics. The lack of current and future gravitational-wave experiments …

Photon–axion-like particle (ALP) oscillations result in the survival of gamma rays from distant
sources above TeV energies. Studies of events observed by CAST, Fermi-LAT, and IACT …

Wave or fuzzy dark matter that is produced with relativistic wave numbers exhibits free-
streaming effects analogous to warm or hot particle dark matter with relativistic momenta …

Axion-like particles (ALPs) are new particles that extend beyond the standard model (SM)
and are extensively investigated. When considering ALPs within an effective field theory …

We present the limits on photon to axionlike particle (ALP) coupling from the 10-year period
observations of the TeV BL Lacertae blazar 1ES 1215+ 303 (with redshift z= 0.130). The …

We investigate the photon-axionlike particle (ALP) oscillation effects on TeV gamma-ray
spectral irregularities from the uncertain redshift active galactic nuclei (AGN) VER J 0521+ …
