Experimental particle physics articles from across Nature Portfolio

Dark matter searches have faced challenges in detecting lighter particles with traditional xenon detectors. The authors propose the HydroX concept, integrating hydrogen into liquid xenon detectors, enhancing sensitivity to lighter dark matter particles and detection capabilities in the field.

While Bell inequalities have been violated several times—mostly in photonic systems—their violations within particle physics experiments are less explored. Here, the BESIII Collaboration showcases Bell-violating nonlocal correlations between entangled hyperon pairs.

Interferometric detection schemes exploit phase-sensitive combination of spatially separated observation to increase sensitivity. Here, the authors combine data from two atomic comagnetometers separated by 860 km to improve limits on axion-like particles across nine orders of magnitude of mass range.

The correlated errors in superconducting qubits have been linked to high-energy particle impacts from cosmic rays, but a direct observation has been lacking. Here, the authors measure the quasiparticle bursts and correlated errors and separate the contributions of cosmic-ray muons and γ-rays in a 63-qubit processor.

Muons are conventionally produced from cosmic rays or with a proton accelerator. Now a proof-of-principle experiment demonstrates the feasibility of muon production with a laser-driven electron beam with gigaelectronvolt energy in a lead converter target.

Intense muon beams are generated at large facilities. A proof-of-principle experiment demonstrates muon generation in the laboratory. Despite lower intensity, the reduced costs of this approach promise to make muon beams available to more scientists.

Antihydrogen is the simplest atom of pure antimatter. Measurements of a pair of ultraviolet spectral lines with laser spectroscopy provide stringent bounds on the magnitude by which a symmetry between matter and antimatter may be violated.

The volume of muon beams in position–momentum space is too large to be used in a collider. A clear reduction in this volume has now been demonstrated, which brings particle physics closer to a practical muon collider for exploring the energy frontier.

Making physics more sustainable raises complex interdisciplinary questions. Answering them needs input from the humanities and social sciences.
