A new measurement of a fundamental particle called the W boson appears to defy the standard model of particle physics, our current understanding of how the basic building blocks of the universe ...

After a decade of meticulous measurements, scientists announced Thursday that a fundamental particle -- the W boson -- has a significantly greater mass than theorized, shaking the foundations of our ...

What is meant, when an experiment anticipates less than a quarter of an event, and four are registered by the detector? That ...

After Higgs Boson: Physics’ Next Move to Understand the Universe It’s been more than a decade since the European Organization for Nuclear Research (known as CERN) discovered the Higgs Boson, using ...

A neutrino with almost unimaginable energy slammed into Earth in early 2023, carrying roughly 220 petaelectronvolts, far ...

The CMS Collaboration has shown, for the first time, that machine learning can be used to fully reconstruct particle ...

Every few years, scientists take a step back to take a broader look at their field and determine what questions are most pressing—and what tools they will need to answer those questions. This year the ...

The model we have for understanding the universe’s fundamental particles is a bit like a gearbox: one tiny change to any one single particles’ properties throws off the mechanics of the other ...

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 ...
