How a mysterious particle could explain the universe’s missing antimatter Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter.

Physicists know that their elegant theoretical description of forces and particles – the Standard Model – must be incomplete, ...

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same uncomfortable conclusion: something is producing signals that the Standard Model of ...

Recent findings from research we have been carrying out at the Large Hadron Collider (LHC) at Cern in Geneva suggest that we might be closing in on signs of undiscovered physics. If confirmed, these ...

A team of theoretical physicists has proposed a new particle existing in a warped fifth dimension that could bridge ordinary matter with dark matter. The model, published in The European Physical ...

For decades, scientists have relied on a popular idea referred to as cosmic inflation to explain how the universe began and why it looks the way it does today. This theory suggests the universe ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...
