Japanese physicists have shown that knots can arise in a realistic particle physics framework, potentially explaining the origin of the universe's matter surplus. By combining two long-studied extensions of the Standard Model, the team found a stable knot configuration that could have formed and dominated in the early universe.
A research team led by Frank Geurts measured quark-gluon plasma temperatures at various stages of its evolution, providing critical insights into a state of matter believed to have existed just microseconds after the big bang. The study revealed two distinct average temperatures depending on the mass range of dielectron pairs, indicati...
Debaditya Biswas combines different particle identification methods with machine learning to detect muons hidden in a sea of pions. He plans to simulate reactions and assess the viability of various techniques, including traditional PID, PSD, and machine learning, to optimize muon detection for future experiments.
A South Korean research team has successfully searched for Dine-Fischler-Srednicki-Zhitnitskii (DFSZ) axion dark matter using a new experimental setup. The group achieved a higher sensitivity than existing experiments, excluding axion dark matter around 4.55 µeV at DFSZ sensitivity.
Physicists develop new theory to explain neutrino properties, solving lepton conservation issues and potential dark matter answers. The research provides predictions testable by the Large Hadron Collider.
Researchers verified predictions of particles beyond standard physics, improving restrictions on theories explaining B meson decay anomalies. The analysis used artificial intelligence to eliminate background data and narrowed the area for searching for new physics.
A team of international physicists, including UC Santa Barbara postdoctoral scholar Manuel Franco Sevilla, reviewed results from three experiments that suggest lepton universality may need to be revised. The findings, published in Nature, indicate a higher-than-expected tau decay rate in all three experiments.
A team of physicists has found new hints of particles being treated in strange ways not predicted by the Standard Model, suggesting evidence for non-standard physics. The discovery could be a significant lead in the search for new phenomena and potentially shed light on dark matter and dark energy.
The article proposes a connection between SLq(2) and the standard model, where preons are creation operators for fundamental particles. This extension describes a finer level of structure than the standard model, with open problems including gravitational binding and renormalization.
The MAJORANA DEMONSTRATOR experiment aims to detect neutrinoless double-beta decay in germanium-76, a process that could rewrite the Standard Model of Particles and Interactions. The detector will use advanced shielding and materials to minimize background noise and detect even the rarest decays.
