Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from ...

The study seeks to explain the presence of dark matter using a WED model. The scientists studied fermion masses, which they ...

Japanese physicists have revived Kelvin’s old idea of cosmic knots, showing how these tangled fields might explain why matter ...

The geometry of space, where physical laws unfold, may also hold answers to some of the deepest questions in fundamental ...

On July 4, 2012, researchers at the Large Hadron Collider (LHC) in Switzerland announced with great fanfare that they had ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

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 ...

In the quest to unravel the mysteries of the universe, physicists are revisiting a 150-year-old theory that could illuminate ...

After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...

As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is “When are you going to find something?” Resisting the temptation to sarcastically ...

The model we have for understanding the universe’s fundamental particles is a bit like a gearbox: one tiny change to any one single particles’ properties throws off the mechanics of the other ...
