Dark SHINE is a newly proposed fixed-target experiment at SHINE (Shanghai high repetition rate XFEL and extreme light facility, being the 1st hard X-ray FEL in China) under construction targeting completion in 2026. Dark SHINE aims to search for the new mediator, Dark Photon, bridging the Dark...

Belle has unique reach for a broad class of models that postulate the existence of dark matter particles with MeVโGeV masses. In addition, the low-background environment of electron-positron collisions and an hermetic detector make Belle II the premier experiment for studying tau-lepton physics. This talk presents recent world-leading results from Belle II searches for dark $Zโ$ decays and...

We present the most recent $BABAR$ searches for reactions that could simultaneously explain the presence of dark matter and the matter-antimatter asymmetry in the universe. This scenario predicts $B$-meson decays into a ordinary-matter baryon and a dark-sector anti-baryon $\psi_D$ with branching fractions accessible at the $B$ factories.

Determination of the nature of dark matter is one of the most fundamental problems of particle physics and cosmology. This talk presents recent searches for dark matter particles from the CMS experiment at the Large Hadron Collider. The talk covers also covers recent searches for strong production of Supersymmetric (SUSY) particles with and some without the SUSY dark matter candidates. The...

The presence of a non-baryonic Dark Matter (DM) component in the Universe is inferred from the observation of its gravitational interaction. If Dark Matter interacts weakly with the Standard Model (SM) it could be produced at the LHC. The ATLAS Collaboration has developed a broad search program for DM candidates in final states with large missing transverse momentum produced in association...

Axion-like particles (ALPs) are pseudo-Goldstone bosons arising from some spontaneously broken global symmetry, addressing the strong CP or hierarchy problems. The BESIII experiment is a symmetric e+e- collider operating at c.m. energy from 2.0 to 4.95 GeV. With the worldโs largest data set of $J/\psi$ (10 Billion), $\psi(2S)$ (2.6 Billion), and about 25 fb-1 scan data from 3.77 to 4.95 GeV,...

The DAMA collaboration's claim of detecting dark matter in the early 2000s remained a long-standing anomaly, and subsequent hypotheses were disproven using different targets. More recently, the COSINE and ANAIS collaboration utilized the same NaI(Tl) target and found that dark matter was not the source of the annual modulation observed by the DAMA collaboration. This presentation will provide...

LUX-ZEPLIN (LZ) is a dark matter direct detection experiment located at the Sanford Underground Research Facility in Lead, South Dakota. At the heart of the detector is a dual-phase time projection chamber containing 7 tonnes of active liquid xenon. During its 1000-day science run, LZ aims to achieve unprecedented sensitivity to Weakly Interacting Massive Particles (WIMPs) down to a...

DarkSide-50 is a direct dark matter search experiment using a dual phase argon time projection chamber at LNGS in Italy. Based solely on the ionization spectrum, it has set the most stringent exclusion limits for several low-mass dark matter candidates. Owing to its peculiar behaviour, dark matter can be searched in a model-independent way exploiting the expected fluctuation of the relative...

Pion decay-at-rest neutrino experiments could also be a copius source of dark sector particles. Experiments looking for the elastic scattering of neutrinos may also be sensitive to decay of nuclei excited by inelastic scattering of both neutrinos and dark matter. Using this channel, with an additional timing cut to reduce the neutrino background, we demonstrate an increased sensitivity to a...

The detection limits for WIMP-nucleon scattering are approaching the neutrino floor where coherent neutrino-nucleus scattering will form an irreducible background for many of the dark matter detector technologies currently in use. CYGNUS is a network of international research groups who aim to use directional detection as a means to penetrate the neutrino floor. Their current focus is R&D...

The scattering of neutral particles by an atomic nucleus can lead to electronic ionisation and excitation through a process known as the Migdal effect. We revisit and improve upon previous calculations of the Migdal effect, using the Dirac-Hartree-Fock method to calculate the atomic wavefunctions. Our methods do not rely on the use of the dipole approximation, allowing us to present robust...

The proposed LUXE experiment (LASER Und XFEL Experiment) at DESY, Hamburg, using the electron beam from the European XFEL, aims to probe QED in the non-perturbative regime created in collisions between high-intensity laser pulses and high-energy electron or photon beams. This setup also provides a unique opportunity to probe physics beyond the standard model. In this talk we show that by...
