We further include fermions with differen t representations in the dark sector. Employing the Polyakov-Nambu-Jona-La sinio (PNJL) model\, we discover that the relevant gravitational wave sign atures are highly dependent on the various representations. We also find a remarkable interplay between the deconfinement-confinement and chiral pha se transitions. In both scenarios\, the future Big Bang Observer and DECIG O experiment have a higher chance to detect the gravitational wave signals . Most recently\, via Quark-Meson model\, we find the phase transition and thus gravitational wave signals will be significantly enhanced when the s ystem is near conformal. In addition\, we find that this effective field t heory approach can be implemented to study the glueball dark matter produc tion mechanism and for the first time provide a solid prediction of glueba ll dark matter abundance. Our prediction is an order of magnitude smaller than the existing glueball abundance results in the literature.\n\nhttps:/ /indico.itp.ac.cn/event/244/contributions/1290/ LOCATION: URL:https://indico.itp.ac.cn/event/244/contributions/1290/ END:VEVENT BEGIN:VEVENT SUMMARY:Closing Ceremony DTSTART;VALUE=DATE-TIME:20240724T032500Z DTEND;VALUE=DATE-TIME:20240724T040000Z DTSTAMP;VALUE=DATE-TIME:20260510T110641Z UID:indico-contribution-244-1286@indico.itp.ac.cn DESCRIPTION:Speakers: Tianjun Li ()\nhttps://indico.itp.ac.cn/event/244/co ntributions/1286/ LOCATION: URL:https://indico.itp.ac.cn/event/244/contributions/1286/ END:VEVENT BEGIN:VEVENT SUMMARY:Introduction for the Axion 2025 Conference DTSTART;VALUE=DATE-TIME:20240723T101000Z DTEND;VALUE=DATE-TIME:20240723T102000Z DTSTAMP;VALUE=DATE-TIME:20260510T110641Z UID:indico-contribution-244-1285@indico.itp.ac.cn DESCRIPTION:Speakers: Yongchao Zhang ()\nhttps://indico.itp.ac.cn/event/24 4/contributions/1285/ LOCATION: URL:https://indico.itp.ac.cn/event/244/contributions/1285/ END:VEVENT BEGIN:VEVENT SUMMARY:Angular correlation by spin-2 ultralight dark matter and deformed Hellings-Downs curve DTSTART;VALUE=DATE-TIME:20240723T063000Z DTEND;VALUE=DATE-TIME:20240723T065500Z DTSTAMP;VALUE=DATE-TIME:20260510T110641Z UID:indico-contribution-244-1275@indico.itp.ac.cn DESCRIPTION:Speakers: Yun-Long Zhang (NAOC(National Astronomical Observato ries\, CAS))\nThe pulsar timings are sensitive to both the nanohertz gravi tational-wave background and the oscillation of ultralight dark matter.

In the st andard cold dark matter (CDM) model\, Population III stars(The first gener ation stars) form in minihalos and affect the 21 cm signal through Ly-alph a and X-ray radiation. Such a process is modulated by the relative motion between dark matter and baryons\, generating the VAO wiggles on the 21 cm power spectrum. In the axion dark matter models for which the number of mi nihalos is reduced\, the VAO wiggles are weaker or even fully invisible. W e investigate the wiggle features in the CDM with different astrophysical models and in different dark matter models. We find that (1) in the CDM mo del the relative streaming velocities can generate the VAO wiggles for bro ad ranges of there important parameters: the star formation efficiency\, X -ray production efficiency\, and the intensity of Lyman–Werner (LW) radi ation\, though for different parameters the wiggles would appear at differ ent redshifts and have different amplitudes. (2) For the axion model with different mass\, the amplitude of the VAO wiggles are also different. In t he mixed model\, the VAO signal is sensitive to the axion fraction. Theref ore\, the VAO signal can be an effective indicator for small-scale density fluctuations and a useful probe of the nature of dark matter. The Square Kilometre Array-low with ~2000 hr observation time has the ability to dete ct the VAO signal and constrain dark matter models.\n\nhttps://indico.itp. ac.cn/event/244/contributions/1252/ LOCATION: URL:https://indico.itp.ac.cn/event/244/contributions/1252/ END:VEVENT BEGIN:VEVENT SUMMARY:Possible Dark Matter Signals from White Dwarfs DTSTART;VALUE=DATE-TIME:20240722T083000Z DTEND;VALUE=DATE-TIME:20240722T085500Z DTSTAMP;VALUE=DATE-TIME:20260510T110641Z UID:indico-contribution-244-1276@indico.itp.ac.cn DESCRIPTION:Speakers: Jia-Shu Niu (Shanxi University)\nIn our galaxy\, the white dwarfs (WDs) will inevitably capture the dark matter (DM) particles streaming through them\, if there exist interactions between DM particles and nuclei/electrons. At the same time\, these DM particles can also be e vaporated by the nuclei/electrons in a WD if they have proper mass and the WD is not too cold. The evaporation of DM particles will lead to a faster cooling evolution than that predicted by the stellar evolution theory.\nI n this work\, we ascribe the faster cooling evolution of three observed WD s to the capture and evaporation of DM particles\, and get the possible re gions of DM particle’s mass and DM-electron cross section.\nThe results are beyond the detection capabilities of current direct detection experime nts and shouldbe cross checked by more novel scenarios in the future.\n\nh ttps://indico.itp.ac.cn/event/244/contributions/1276/ LOCATION: URL:https://indico.itp.ac.cn/event/244/contributions/1276/ END:VEVENT BEGIN:VEVENT SUMMARY:High-Quality Axions in a Class of Chiral U(1) Gauge Theories DTSTART;VALUE=DATE-TIME:20240722T074500Z DTEND;VALUE=DATE-TIME:20240722T081000Z DTSTAMP;VALUE=DATE-TIME:20260510T110641Z UID:indico-contribution-244-1251@indico.itp.ac.cn DESCRIPTION:Speakers: Jin-Wei Wang (UESTC)\nWe show that there are many ca ndidates for the quintessence and/or the QCD axions in a class of chiral $ U(1)$ gauge theories.

Additionally\, solar neutrino data places a s trong limit on the model but provides a weaker constraint on the (g−2)μ parameter space due to a sign mismatch.

Bosonic stars are spatially e xtended objects that can not be treated as point particles. We give a full y analytic calculation for the tidal perturbation from randomly distribute d diffuse objects\, and derive a form factor that fully take account of th e size effect of solitons. We then discuss their evaporation effects on is olated\, a.k.a. `halo-like' wide binary systems in our Galaxy\, and identi fy high-probability `halo-like' candidates from GAIA with separations larg er than 0.1 pc. Survival of the farest-separated candidates will provide a novel gravitational probe to dark matter in the form of solitons. In the case of axion-like solitons\, the observational sensitivity is shown to ex tend into the axion mass range of m_a ~ 10^-15 - 10^-17 eV.\n\nhttps://ind ico.itp.ac.cn/event/244/contributions/1261/ LOCATION: URL:https://indico.itp.ac.cn/event/244/contributions/1261/ END:VEVENT BEGIN:VEVENT SUMMARY:Dark Photon Dark Matter in QEMD and detection DTSTART;VALUE=DATE-TIME:20240724T012000Z DTEND;VALUE=DATE-TIME:20240724T014500Z DTSTAMP;VALUE=DATE-TIME:20260510T110641Z UID:indico-contribution-244-1260@indico.itp.ac.cn DESCRIPTION:Speakers: Rui-jia Zhang (Nankai University)\nIn this work\, we construct the dark photon-photon interactions in the framework of QEMD an d obtain new dark photon-photon kinetic mixings.

With two hierarchical symmetry-breaking scales\, the model exhibits three distinct string solutions: a conventional global string\, a global string with a heavy core\, and a gauge string as a bound state of the two global strings. This model reveals rich phenomenological implicat ions in cosmology. When incorporating this model with the QCD axion framew ork\, the heavy-core global strings emit more axion particles due to their large tension. This radiation significantly enhances the QCD axion dark m atter abundance\, thereby opening up the QCD axion mass window. Furthermor e\, in contrast to conventional gauge strings\, the gauge strings in this model exhibit a distinctive behavior\, radiating axions.\n\nhttps://indico .itp.ac.cn/event/244/contributions/1255/ LOCATION: URL:https://indico.itp.ac.cn/event/244/contributions/1255/ END:VEVENT BEGIN:VEVENT SUMMARY:SKA radio probes on axion-like particles and MeV scale dark matter DTSTART;VALUE=DATE-TIME:20240724T014500Z DTEND;VALUE=DATE-TIME:20240724T021000Z DTSTAMP;VALUE=DATE-TIME:20260510T110641Z UID:indico-contribution-244-1254@indico.itp.ac.cn DESCRIPTION:Speakers: Kenji Kadota ()\nWe discuss the sensitivity of the S KA radio telescope to sub-GeV dark matter and axion-like particles.\nSpeci fically\, we explore how these light dark matter candidates affect large-s cale structure formation and generate 21 cm radio signals detectable by th e forthcoming SKA radio telescope.\nAdditionally\, we demonstrate that MeV -scale dark matter can be probed through radio emissions from the magnetos pheres of white dwarfs.
