5. Axion search results in PandaX
小朋 周 (北京航空航天大学)

Besides WIMPs, axion is also a perfect candidate for dark matter particle. Based on the couplings between axion and electron, solar axion can bombard electrons of xenon, leaving a detectable electron recoil signal. We have achieved a series of axion search based on the PandaX-II data. And in the near future, the new results from PandaX-4T will come.
9. Axion-photon conversion of LHAASO multi-TeV and PeV photons
Bo-Qiang Ma (Peking University)

The Large High Altitude Air Shower Observatory (LHAASO) has reported the detection of a large number of multi-TeV-scale photon events including also several PeV-scale gamma-ray-photon events with energy as high as 1.4~PeV. The possibility that some of these events may have extragalactic origins is not yet excluded. Here we propose a mechanism for the traveling of very-high-energy (VHE) and...
8. Axionic Dirac seesaw and electroweak vacuum stability
Prof. Xinyi Zhang (Hebei University)

We explore the connection between tree-level Dirac neutrino masses and axion physics in a scenario where the PQ symmetry enforces lepton number conservation perturbatively. Requiring that the PQ scale $f_a$ is the only heavy scale to play a role in neutrino mass generation, we are led to the construction of a KSVZ-type model where Dirac neutrino masses are inversely proportional to $f_a$,...
6. Characterization of massive ALP emissivity from a core-collapse Supernova
Dr Alessandro Lella (University of Bari, INFN)

ALPs could be copiously emitted during a supernova explosion by means of nuclear processes. The two main processes for axion production in a nuclear medium are nucleon-nucleon Bremmstrahlung N+N→N+N+a and pionic Compton-like processes π^-+p→n+a. The aim of the work is to extend the results already present in the previous literature to the case of massive axions, considering corrections due to...
3. Detecting Axion Dark Matter through the Radio Signal from Omega Centauri
Dr Jin-Wei Wang (TDLI)

As a well-motivated dark matter candidate, axions can be detected through the axion-photon resonant conversion in the magnetospheres of magnetic white dwarf stars or neutron stars. In this work, we utilize Omega Centauri, which is the largest globular cluster in the Milky Way and is suggested to be the remnant core of a dwarf galaxy, to probe the axion dark matter through radio signals that...
2. Opening up window of post-inflationary QCD axion
Lingfeng Li (Brown University)

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 the axion decay constant, $f_a$, is (much) above the inflationary Hubble scale, $H_I$. This is achieved through the heavy-lifting of the PQ scalar field due...
4. Optical circular polarization induced by axion-like particles in blazars
Mr Runmin Yao (IHEP, CAS)

We propose that the interaction between the axion-like particles (ALPs) and photons can be a possible origin of the optical circular polarization (CP) in blazars. Given that there is no deterministic detection of the optical CP at $\sim0.1\%$ level, a rough limit on ALP-photon coupling can be obtained, specifically $g_{a\gamma}\cdot B_\mathrm{T0}<7.9\times10^{-12}~\mathrm{G\cdot GeV}^{-1}$ for...
7. Pulsar timing residuals and wideband ultralight dark matter
Dr Yun-Long Zhang (NAOC)

The coherent oscillation of ultralight dark matter in the mass regime around 10-23  eV induces changes in gravitational potential with the frequency in the nanohertz range. This effect is known to produce a monochromatic signal in the pulsar timing residuals. Here we discuss a multifield scenario that produces a wide spectrum of frequencies, such that the ultralight particle oscillation can...
10. QCD axion dark matter and the cosmic dipole anomaly
成成 韩 (Sun Yat-sen University)

There is growing evidence that the cosmic dipole measured from the distant galaxy number-count is not consistent with that of CMB and the deviation is getting close to 5σ. We find that the QCD axion, a hypothetical particle originating from the spontaneous breaking of the Peccei-Quinn symmetry, could explain this dipole anomaly if it constitutes the dark matter of our universe. This model...
11. Solutions to axion electromagnetodynamics and new search strageties
Rui-jia Zhang (Nankai University)

The Witten effect implies the electromagnetic interactions between axions and magnetic monopoles. Based on the quantum electromagnetodynamics, a generic low-energy axion-photon effective field theory was built by introducing two four-potentials ($A^\mu$ and $B^\mu$) to describe a photon. More anomalous axion-photon interactions and couplings ($g_{aAA}$, $g_{aBB}$ and $g_{aAB}$) arise in...
