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 ...

In a discovery that has physicists relearning how to count, three teams around the globe report that they have identified a subatomic particle consisting of five quarks -- a number never before seen ...

A team of physicists at the University of Massachusetts Amherst recently hypothesized that the event that occurred in 2023, when a subatomic particle called a neutrino crashed into Earth with such ...

A single subatomic particle that hit Earth in 2023 carried roughly 100,000 times more energy than anything humanity has ever ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

The nature of dark matter is largely unknown, but it is thought to have mass, which influences particle interactions in the universe through gravity. Dark matter may not interact much with visible ...

Muons are getting a move on. In a step toward new types of particle physics experiments, scientists cooled and then accelerated a beam of muons. The subatomic particles, heavy cousins of electrons, ...
