From the outside, the high-speed collisions of atomic nuclei inside particle accelerators like CERN’s Large Hadron Collider (LHC) may seem like they have very little in common with more mundane ...

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 ...

Building experimental evidence suggests that the electron, muon and tau may feel different forces. When the tau lepton was discovered in the 1970s, it didn’t resolve any outstanding mysteries—it ...

The Standard Model of particles and interactions is remarkably successful for a theory everyone knows is missing big pieces. It accounts for the everyday stuff we know like protons, neutrons, ...

Particle and high energy physics seeks to understand the fundamental constituents of matter and the interactions that govern them across the smallest distance scales and highest energies. The Standard ...

Researchers from the CMS collaboration have analysed data from proton-proton collisions in an attempt to find cracks in the Standard Model of particle physics The CMS detector at CERN has continues to ...

Jet constituents are given as the input to a ML model to predict properties of the hadronically decaying tau leptons. In order to find rare processes from collider data, scientists use computer ...

The quarks, antiquarks, and gluons of the standard model have a color charge, in addition to all the other properties like mass and electric charge that other particles and antiparticles possess. All ...

“I was actually shaking,” said Mitesh Patel, a particle physicist at Imperial College, London, as he describes the moment he saw the results. “I realised this was probably the most exciting thing I’ve ...

Particle physics is a field of extremes. Scales always have 10 really big number associated. Some results from the Large Hadron Collider Beauty (LHCb) experiment have recently been reported that are ...
