Ponderomotive effects of ultralight dark matter

Journal of High Energy Physics
I exhibit a new class of quadratic effects of ultralight dark matter. Axions, dark photons, and dilatons can exert rapidly oscillating forces, torques, and mass shifts on Standard Model particles.

ALP-ine quests at the LHC: hunting axion-like particles via peaks and dips in $$ t\overline{t} $$ production

Journal of High Energy Physics
Abstract We present an analysis of the sensitivity of current and future LHC searches for new spin-0 particles in top–anti-top-quark $$ \left(t\overline{t}\right) $$ t t

Exploring interference effects between two ALP effective operators at the LHC

Journal of High Energy Physics
We observe that most studies of axion-like particle (ALP) production channels at the Large Hadron Collider (LHC) focus on a single type of ALP operator for each process in the effective field theory framework.

Relativistic Axion with Nonrelativistic Momenta: A Robust Bound on Minimal ALP Dark Matter

The axion-like particle (ALP), a pseudo Nambu-Goldstone boson that couples to two photons, has been studied extensively in recent years as a dark matter candidate. For initial field configurations in a minimal ALP model explaining the observed dark matter abundance, we need the potential height to exceed the ALP energy density at redshift $z\approx 5.5\

Axion detection via superfluid 3He ferromagnetic phase and quantum measurement techniques

Journal of High Energy Physics
We propose to use the nuclear spin excitation in the ferromagnetic A1 phase of the superfluid 3He for the axion dark matter detection. This approach is striking in that it is sensitive to the axion-nucleon coupling, one of the most important features of ...

Froggatt-Nielsen ALP

Journal of High Energy Physics
The Froggatt-Nielsen (FN) mechanism, a prominent framework for explaining the observed flavor hierarchies, generically predicts the existence of an axion-like particle (ALP). This work examines a class of FN models based on ℤ N discrete symmetries.

Physical signatures of fermion-coupled axion dark matter

Journal of High Energy Physics
In the presence of axion dark matter, fermion spins experience an “axion wind” torque and an “axioelectric” force. We investigate new experimental probes of these effects and find that magnetized analogs of multilayer dielectric haloscopes can explore ...

Probing the gauge-boson couplings of axion-like particle at the LHC and high-luminosity LHC

Journal of High Energy Physics
In this work, we calculate the sensitivities on the gauge-boson couplings g aZZ , g aZγ , and g aWW of an axion-like particle (ALP) that one can achieve at the LHC with s $$ \sqrt{s} $$ = 14 TeV and integrated luminosities of 300 fb−1 (current run) and ...
