A new type of particle has been discovered by scientists at CERN using data from last year's run of the Large Hadron Collider (LHC). The particle opens the door to a "new frontier" of physics, ...

Scientists at the University of Illinois Urbana-Champaign have confirmed the existence of a massless particle, long theorized ...

Two recent studies by Professor Stefano Profumo at the University of California, Santa Cruz, propose theories that attempt to answer one of the most fundamental open questions in modern physics: What ...

Scientists at CERN’s Large Hadron Collider (LHC) have for the first time observed a fundamental asymmetry in the behavior of baryons, the particles that form the bulk of all visible matter. The ...

A new type of particle may have shown up independently at two particle accelerators, physicists say. The particle, made of four quarks (the ingredients of protons and neutrons), appears to represent a ...

Matter is a lush tapestry, woven from a complex assortment of threads. Diverse subatomic particles weave together to fabricate the universe we inhabit. But a century ago, people believed that matter ...

The Standard Model of particle physics does a decent enough job of explaining the universe, but it still has some holes in it. Now, a new study outlines how one hypothetical particle, the axion, may ...

"When my student showed me the data I thought she must be wrong," Boston College professor and lead researcher Kenneth Burch told Live Science. "It's not every day you find a new particle sitting on ...
