A new theory suggests the universe’s greatest secrets are hiding in a “zeptouniverse” that’s ready to be explored—without ...

What is meant, when an experiment anticipates less than a quarter of an event, and four are registered by the detector? That number discrepancy lies at the heart of a new conundrum of kaons: ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Over time, particle physics and astrophysics and computing have built upon one another’s successes. That coevolution continues today. In the mid-twentieth century, particle physicists were peering ...

Physicists have found that an elementary particle called the W boson appears to be 0.1% too heavy — a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

Something odd is happening deep inside the data streams from CERN’s Large Hadron Collider. A set of “forbidden” patterns in how unstable particles decay, combined with rare Higgs events and a ...

Energetic particles that arise when cosmic rays hit Earth’s atmosphere could help assess hidden damage to buildings in Ukraine after the war. Primordial black holes may be exploding throughout the ...
