- Large Hadron Collider detects strange particle behavior that could rewrite physics
Scientists at CERN's Large Hadron Collider observed unusual particle behavior in rare 'penguin decays' that may indicate physics beyond the Standard Model. The discrepancies suggest unknown particles or forces could be influencing the results.
- Scientists were wrong about this “rule-breaking” particle
Scientists discovered that an apparent anomaly in the muon particle was likely a calculation error, confirming the Standard Model's validity. The error was found after years of supercomputer calculations. The finding resolves a decades-long pursuit of a mysterious new force.
- The exotic particles that could finally break the Standard Model
A recent CERN experiment at the Large Hadron Collider observed 'Penguin' decays that suggest the presence of new physics beyond the Standard Model. The findings, published in Nature in May 2026, could challenge existing theoretical frameworks in particle physics.
- Daily briefing: Five inspiring science stories to lift your mood
The article highlights five inspiring science stories and mentions exotic particles that could break the Standard Model. It aims to lift the reader's mood with positive scientific developments. These stories were published in Nature on May 1, 2026.
- Physicists think they've solved the muon mystery
Physicists have resolved a 20-year discrepancy in muon magnetic property calculations, concluding it was a calculation error rather than evidence of new physics. A new study in Nature confirms the Standard Model remains valid, as the discrepancy was not due to a fifth force.
- Hybrid calculation of hadronic vacuum polarization in muon g − 2 to 0.48%
A new hybrid calculation combining experimental and lattice data validates the standard model's prediction for the muon's anomalous magnetic moment to 11 decimal places, achieving 0.48% accuracy. The study, published in Nature, uses a multi-energy-range approach to refine hadronic vacuum polarization contributions.
- High-precision measurement of the W boson mass with the CMS experiment
The CMS experiment at CERN conducted a high-precision measurement of the W boson mass, confirming alignment with Standard Model predictions. This result contradicts recent anomalous measurements, highlighting consistency in particle physics theories.
- High-precision measurement of the W boson’s mass lends weight to the standard model
A high-precision measurement of the W boson's mass aligns with the standard model of particle physics, contradicting earlier anomalous results. This finding strengthens confidence in the standard model's validity.
