Intrinsically Quantum Effects of Axion Dark Matter are Undetectable Open
Is the usual treatment of axion dark matter as a classical field reliable? We show that the answer is subtle: the axion field could well be in a quantum state that has no complete classical description, but realistic detectors cannot tell …

Anatomy of Parity-violating Trispectra in Galaxy Surveys Open
Parity-violating interactions are ubiquitous phenomena in particle physics. If they are significant during cosmic inflation, they can leave imprints on primordial perturbations and be observed in correlation functions of galaxy surveys. Im…

Accidental suppression of Wilson coefficients in Higgs coupling Open
A bstract Higgs couplings are essential probes for physics beyond the Standard Model (BSM) since they can be modified by new physics, such as through the Higgs portal interaction $$ {\left|H\right|}^2\mathcal{O} $$ . These modificati…

Accidental Suppression of Wilson Coefficients in Higgs Coupling Open
Higgs couplings are essential probes for physics beyond the Standard Model (BSM) since they can be modified by new physics, such as through the Higgs portal interaction $|H|^2\mathcal{O}$. These modifications influence Higgs interactions v…

Opening up a Window on the Postinflationary QCD Axion Open
The QCD axion cosmology depends crucially on whether the QCD axion is present during inflation or not. We point out that contrary to the standard criterion, the Peccei-Quinn (PQ) symmetry could remain unbroken during inflation, even when t…

Electroweak ALP Searches at a Muon Collider Open
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. This feature, togeth…
