Titanium diselenide, strontium ruthenate and hole-doped diamond host low-energy electron waves called plasmons that amplify the faint kick a light dark matter particle would deliver, physicists report in Physical Review Letters. All three can be made today.
Physicists used entangled lambda hyperons to measure how often a strange quark turns into an up quark. The numbers still add up to one — and still disagree slightly with the older kaon measurements.
The GlueX experiment aimed a photon beam at protons to confirm a 20-year-old particle candidate. It missed that target and instead found evidence for two previously unseen structures, one of them at the five-sigma threshold physicists treat as a discovery.
XENONnT pushed the direct detection threshold for neutrinos lower than anyone has managed before. The signal comes from the proton-proton fusion that powers the Sun.
LUX-ZEPLIN found a single high-energy interaction sitting exactly where dark matter should appear and where almost no background should. At 2.6 sigma, it is nowhere close to a discovery.
SuperCDMS SNOLAB has begun taking its first science data. Its shielding includes lead salvaged from ancient ballast on the floor of the Mediterranean.
Physicists thought you needed lead — 200 times heavier than a proton — to melt matter into quark-gluon plasma. Oxygen and neon just did it, and ALICE, ATLAS, CMS and LHCb all saw it independently.
A specially shaped mirror sweeps a laser's focal point down the beam axis at the vacuum speed of light, defeating the 'dephasing' ceiling that has capped plasma accelerators. Electrons hit 396 MeV where the limit predicted 185.
XENONnT found nothing — and that nothing is the tightest limit yet on axion-like particles and dark photons. It is the first detector to reach the boundary where the sun's own neutrinos start masquerading as a signal.
The BESIII collaboration in Beijing reported that a particle called X(2370) is dominated by a pseudoscalar glueball, a knot of gluons with no quarks in it at all, closing in on one of quantum chromodynamics' oldest unconfirmed predictions.
A Japanese team used the cavity between Earth's surface and its ionosphere as a natural resonator, then searched a decade of magnetic-field recordings from a Scottish observatory for the signature of axions.
The Double Chooz experiment logged about 100 antineutrinos during 17 days when both reactors next door were shut down — the first measurement of its kind, and a possible new tool for catching cheating on nuclear treaties.
