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 ...

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 ...

Scientists ran a comprehensive analysis of data from collisions of heavy ions (the nuclei of atoms) to determine which factors most influence fluctuations in the flow of particles. They found that the ...

It is unusual for TV news to open with a story about physics, but it happened on July 4, 2012, when all around the world stations chose to devote prime time to breaking news from Geneva: a search of ...

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 ...

At 00:38 CEST this morning, the LHC shift crew declared ‘stable beams’ as two 4 TeV proton beams were brought into collision at the LHC’s four interaction points. This signals the start of physics ...

Physicists at the Large Hadron Collider (LHC) in Europe have explored the properties of nature at higher energies than ever before, and they have found something profound: nothing new. It’s perhaps ...
