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 ...

The Particle Physics Project Prioritization Panel (P5) whose participants include a UT physicist delivered recommendations to decision makers. ATLAS detector at the Large Hadron Collider at CERN.

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 ...

Over a century ago, Ernest Rutherford discovered the proton by splitting the atom in a laboratory in Manchester. Today, researchers based in Manchester have discovered a new particle that Rutherford ...

There are many outstanding questions about the universe: What is the nature of dark matter? Why is the universe expanding? How do neutrinos acquire their mass? Because experiments to answer these ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

A novel theory of 'wavy space-time' suggests that the division between our best descriptions of the universe on its smallest and largest scales may be because gravity does not play by quantum rules.

Particle physics seeks to understand the fundamental constituents of matter and the forces that govern their interactions. The field has evolved from early studies of protons, neutrons and electrons ...
