The first data from proton–lead collisions at the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at CERN include a “ridge” structure in correlations between newly generated ...

In a paper in Nature, the ALICE Collaboration 1 reports that data from high-energy collisions between protons can be used to investigate the little-understood nuclear forces between protons and ...

Smashing atomic nuclei together at mind-bending speeds recreates the fiery conditions of the early universe and scientists are finally getting a better handle on what happens next. A sweeping new ...

Mathematicians and physicists have noticed a strange coincidence occurring between their respective fields: the values computed from particle physics experiments seem to correspond with a specific set ...

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 CMS collaboration at CERN have searched for evidence of long-lived particles beyond the Standard Model in proton-proton collision events Despite the huge success of the Standard Model of particle ...

Scientists at the Large Hadron Collider, the world’s leading instrument for understanding the nature and structure of subatomic physics, announced March 30 that the LHC had collided particles to 7 ...

At the smallest scales, everything in the universe can be broken down into fundamental morsels called particles. The Standard Model of particle physics—the reigning theory of these morsels—describes a ...
